Crank No Start Diagnosis Nissan Altima
HTML-код
- Опубликовано: 23 мар 2020
- In today's video I will be walking you through the process of diagnosing a does crank but does not start also known as crank no start symptoms. Oftentimes a crank no start situation is caused by a bad fuel pump or bad crank sensor. What we will do is try spraying starter fluid to see if it cranks and then cuts off, that would let us know if the Altima has a bad fuel pump, and then we will try testing for fuel injector signal and Spark signal which would let us know if the nissan crank sensor or crankshaft position sensor or cam sensor, or camshaft position sensor is doing its job correctly. Another reason you would not get crank or cam sensor signal is because this Nissan altima itself is not giving the signal on purpose. That was the situation for my customer car today the transponder from the key had fallen out from the key and the car was not reading the keys chip or transponder which made it not give signal to the sensors to start. The car does this in case somebody's trying to hotwire your car it will not start that why it looks for the transponder signal from the key.

Thank you bro youre the best i got my car running cuz of you.👍
A Blown Ignition 15A FUSE will cause CRANK NO START. LOCATED IN FUSE BOX ENGINE COMPARTMENT/PASSENGER SIDE
Could this be the cause with a 2016 Nissan Altima?
@@lenasblessed22 check your brake switch sensor it’s common in that year
Im going thru this right now. Same year. Cranks but wont start. My friend says coil pack. Im going to look at fuses during the day
@@shell_n_her_dog3659 mine had tons of oil inside the coils so replaced the valve cover and haven’t had issues since
@@alexquezada510 i had a different friend come look at it and he said it was the fuel pupm. So ive had one friend come tell me what u said coil packs & another say something else.. Omg idk which one is right
Thanks! Your video was very helpful and easy to understand. You covered all bases. THANKS!!
Love the video determination even in the rain!
Great video
Thank you
Bro great video very very helpful ❤
Great video to the point, informative,clearly said,and nothing to do with his personal life.
Great video
INFO: my dad is a 25+ year mechanic and we had a 30+ year nissan tech come and look at it.
Replaced the head gasket (I replaced the head bolts with ARP branded ones) and after it would crank but ran really rough. I made sure the the head and block were perfectly flat cause they can warp when overheating which was my original issue. I made sure that I set the timing perfect. Then it went into NATS and I had to send the ECM to a place to remove NATS. Then it wouldnt start at all unless we unplugged the crank sensor. Bought a new cam and crank sensor, new coils etc. After this the coils started to literally explode. The nissan tech said hes only seen the coils explode on 2 cars due to the wiring harness wearing out and starting to short somewhere. I checked the harness with no signs of shorting. Even bought an oscilloscope to make sure the coils worked right and they were running fine. My only thought is that maybe the timing is half a tooth off causing it to sometimes runs but bogs down at higher RPM. Ive spent 50+ hours trying to figure it out. Also each cylinder had perfect compression. Before all this bs happened it was eating coolant cause of the head gasket so I took it to the dealer which they said I needed a new valve cover gasket which made me facepalm a bit but I said fuck it just to prove they were fucking stupid. They ran the car with the valve cover off and said they put new coolant in it. I got a mile down the road and the fucker overheated cause they lied and the radiator was completely empty and dry.
So I drove my 05 Altima 3.5 the other day home. It upshifted then died. Would crank but wouldn’t start. I went to autozone to get a crankshaft position sensor, installed it and still same symptoms. Cranks but doesn’t run. I just read your comment about disconnecting it and sure enough it started but ran rough. Then died again!
I assume get a sensor from the dealership?!
Did you get it fixed and what was the issue?@@maxboya
@@scottk27332 motor skipped timing and bent the valves had to junk the car
WOW so sorry to hear that, I am hoping that's not the case with mine. I just bought it, replaced all the coils and plugs, valve covers, and it ran perfect for a day. Very quiet when running! Got home, tightened up battery terminals and played with some lights and went to move it and it jerked, now its a crank no start....hoping for the best and will check timing now as well@@maxboya
Thanks bro
You're a good dude!
Thankyou!
Question i had to put a battery in my 2001 nissan altima that didn't match but it was close just a slightly higher cold crank like 20 amps higher and thats when it started to take a good 30 seconds to a min of constant cranking to start i have the right one now but its still doing it but after the first long start its fine as long as I don't leave it sitting for a while I know I burnt something out but don't know what any ideas
I have an 05 Nissan Altima, and I having these same issues. I added a new fuel pump in there myself, new camshaft/crankshaft sensors, new thermostat (needed to change it anyway), and I was getting the same crank/no start issue - except it wanted to start but looked like it wasn't getting any spark. So the only resolutions that I can think of are either the PCV valve, the fuel injectors need to be clean, or the Ignition coils need to be replaced - since it started back up after buying a new ignition coil that wasn't providing spark. Then the car reverted to not starting back up after I turned the car off to get gas.
Ever figure out the issue?
@@SJ-qf4mj blown head gasket
What I'm actually passing through now.. any solution to yours?
Thank ypu
Skips when starting , cranks and cranks but no start , replaced spark plugs , fuel pump won’t start but prior to this was skipping then started , the saw smoke behind engines and and over heat needle went all the way up any ideas what else could be
I change the crankshaft position sensor/circuit today cause it had a check engine light for it but it still take long to turn on but not as much as it did before I fix it
Now do the pcv valce and crack sensor right next to the camshaft and you'll have a new car
Cam sensor will cause crank no start too (happened to mine) - was an easy $75 fix.
Are you saying if you do not get injector pulses it also will not get spark? I don't have a noid light, can I check for injector pulses with a regular test light?
You could have mentioned "no compression" will cause a no start condition, as is my case because my friend ran the car with no coolant until the head warped and the engine shut down leaving him stranded. The give away was he mentioned that when he stopped there was "oily" smoke billowing from the engine, and when I arrived to help him 15 minutes later there was no coolant on the ground, nor in the engine, so he'd run out miles back and just kept driving until it died...
Excuse me, how much pressure should I reach when you open the switch? these cars
Is there a fuse or relay that will cause crank no start.
I have this issue right now. Crank no start which lead me to this youtube video.
Did you get it fixed? What was the issue?
I no longer own that car & do not remember what the issue was. My uncle had it repaired for me.
What if it cranks and the fuel pump is confirmed to be fine?
Hi, I have a Nissan 11/2012 Altima.
The Motor turns but will not start.
I checked the fuel pump and gushes out like a fire hose . Works fine.
I checked the connections on top of the manifold got current no problem.
Is it possible that my fuel injectors may be clogged and may need cleaning with a major tune up?
Hey did you find a solution?
I have a question for you if you can answer my questions
I had an intermittent crank-no-start situation that turned out to be a bad cam or crankshaft sensor (I can't remember which one) ... but it wouldn't let the engine ignite. It would just flub out. It sounded like it was choking or not getting enough gas. It turned out that the sensor had been recalled from but no one had ever changed it. I bought the car used after the recall period was closed.
I am currently having crank no start in my daughters 06 Altima 2.5. OBD is showed camshaft pos sensor. I changed both camshaft and crankshaft sensors and the car is still doing the same thing. Even though one of the codes went away. I even disconnected the negative for a while to resent everything. My next guess is a fuel filter since she runs the car on 1/4 too often.
@@69ChevyGarage Did you resolve it, what was the issue?
@@scottk27332 change the crankshaft and camshaft position sensors with Nissan factory ones only. Do not use any other brands. That solved my issue and my codes went away.
Thanks man!
I have Nissan Altima 2006, whenever i try to start it,it takes a while to start (not immediately as it should be)
The fuel pump, coils on plug and spark plugs are good
What else could be?
Broken ground cable to the transmission from negative terminal on batter( they break where they meet the transmision). If thats not it i woild replace crank sensor and check fuel pressure
We have the same problems and same functional parts. What’s your end of story? Is it because the camshaft sensor?
My altima cranks very weak. New battery, spark plugs, there is current on all 4 coils, fuse is ok, starter works. I dont have a fuel tester, but I disconnected the line and it squirts very strong everytime I turn the key
Go to dealer just had to replace BCM due to replacement key
You said flat head screwdriver, push it in and spray starting fluid, you mean push in the butterfly valve inside the throttle body? Would this require a throttle relearn if it did start? Also, spark plugs and ignition coil generally wouldn't cause an engine shut off while driving, then crank and no start...any other recommendations? Cam and crank pos sensors have already been replaced, still no start. And my understanding is that the fuel pump doesn't usually die while vehicle is driving, it's usually after a shut off it won't start back up. I'm stumped and been trying to fix my daughter's 05. Pump hums when ignition turned to on. This momma is getting frustrated
Pcr Valve
Located behind and under your coil packs under the harness
So it's turning just not starting should I switch out the fuel pump it's been sitting for about a year now
Yea. I just replaced mine 2 days ago and change the fuses.
If you have a no start condition, spray starting fluid. If If fires, it's a fuel pump or relay. If it doesn't, it's a crank or cam sensor. Not likely a ecm. If you change sensors, Check wiring or bad aftermarket sensor.
So do you leave the screwdriver in when you try to crank the car?
never use fuel throttle body cleaner directly into throttle body. this particular engine is not designed to be sprayed directly .... instead spray a cloth or towel and wipe the blades only. spraying that directly into throttle body will cause immediate future problems
Have 05 Nissan Altima won't start the dealer said it was head gasket but not 100 percent sure
Bro, thanks for this imformative video. Im having the same issue. Just bought a 2005 Nissan Altima 2.5.. the recent owner had it sitting for a year because he Lost the original key. I came by and offered him money for the vehicle until I managed him to say yes. I called a locksmith to make a key. Fist day it ran good. Same night it rained, next day no start and battery was death. Went and bought new battery and did not start. So I called locksmith and he reprogram the key? Car started again, 2 days later car won't start. Am I missing something here?
did you find out?
might be the alternator draining the battery gotta get it replaced
so if i did get it to want to start by spraying starter fluid into throttle body does that elimate the censors and coil and stuff. should i replace the fuel pump.
Did you replace the fuel pump
Have a 2006 Maxima, cold starts, will run as long as it is cranked up, sits and will run without any trouble for overr 30 min, shut the car off sometimes will restart, but when I let the car but for over 20 min will not restart, what can thus be, have changed the crank sensor, checked the fuses, fuel pump is pushing fuel to the motor, gave examined everything til I'm confused, please help!
Debra Watson I’m Having The Same Problem
@@DevianaRaquell just thought I'd let you know I found out my problem, or shall I say it fixes the problem, if the security lights stays on when you turn the car over, the problem is the security, u was told I had to take my car to the dealership and pay lits of money to have this fixed, but after several days if doing this and doing that, I have found a way to bypass the security with the key, maybe this is a fix for you, if not let me know and I'll walk you through it, maybe have the temperature sensor checked and replaced, had found out that this little sensor does more than control your temper of the car, if I can help you I sure will,
@@debrawatson8368 hello, could you please let me know how you bypassed the security issue? It would be very much appreciated!
Bro spraying starter fluid into the intake plenum and an electronic throttle body is an all around no go. You ginna fuck up the idle even moving that valve and gonna need a reset.
And what if your getting fuel no spark
What if I just replaced my fuel pump ignition coils fuel injectors plenum gaskets spark plugs alternator and radiator but it still takes me 2 to 4 cranks first thing in the morning when I fresh start the car. 2006 Nissan Altima 2.5 SL. After I start it the first time in the morning it seems to be okay starting throughout the rest of the day. It's only when I let it sit overnight it won't start first thing in the morning the first time.
Damn that sucks just change your cam and crank sensors fixxed
Ever figure it out? I had a similar issue and it was just the battery. I guess after getting it started the alternator would charge it up, but sitting over night it lost a good amount of charge making it not want to start first thing In the morning.
@@SJ-qf4mj oil was leaking into one of the cylinders causing it to stall start. After having the issue about 20k miles, blew the motor. I got totalled out but GEICO and bought a 2011 Highlander. #truth
I have the SAME problem.... It used to want to start...now it skips. My 2005 nissan altima 4 cylinder was running hot so, I put coolant... I feel so helpless considering I put 5k into this car..... Please? Anyone have some advice? It would be much appreciated... Ive been told by 2 people that they think the gasket is BLOWN but, I don't know anymore...
My Maxima 2as getting a little hot also, I changed the temp sensor,fans and charged the air and thus was a tux for me and also the car started right up and not running hit any longer, if the car has a blown head gasket there would be moisture and water coming out if the tail pipe, unless the head is worped, these cars I have found to be controlled by so many sensors and if 1 is bad than there's is others,
Do you see any coolant leak? I have one and I hat over heating issues and it was leaking by the water pump and I install a new one with a new seal and it’s all good now.
If it starts when cold but not after its warm call Nissan about the overheating crankshaft sensor recall. They reprogram the PCM to fix.
It will Crank. But it won't try to start is what you meant to say. The Starter cranks. If no spark, it will crank but not attempt to fire
Would the cam position sensor always throw code? ruclips.net/video/dsWnMA5V10k/видео.html update: push on gas while starting and it’s fine again..?!

Bruh you said it cranks and no start but u titled it no crank no start
Great video
