What do we do if there's no fuel coming through? I'm thinking is there a way to test fuel pressure in the lines? Replace fuel filter first? Thank you RSVP ASAP 93 Corolla Wagon
peter i am working on same motor , gas tank was leaking ,,, but before the tank was replaced car was running, after the tank was dropped and replaced , i am not able to have car running , there is no juice to fuel pump replace all the relays and checked every fuse but still no power to fuel pump , i really dont know what more can be done read the manual unless this car has safty shut off switch which according to my sorces there is none i really dont know what more should i do
Hi Peter, I have intermittent stalling on a cold start. Engine will sputter and stall. Once it gets warmed up, it runs fine, so I don't think it's the fuel pump. Maybe dirty fuel injectors?
@@PeterFinnTheCarDoctor Cool I already replaced the fuel filter to no avail. I'll try cleaning the throttle body and go from there. Will also keep running fuel system cleaner through it. Thanks!
@@Mosiano I still haven't figured it out. It looks like it might be an electrical problem. Either the distributor/ignition module, or the ECU itself. Will keep you updated on what I find
Do you have, or know of, a video showing how to replace the entire fuel pump assembly (with the two metal lines) from beginning to end, starting with the pump itself under the rear seat, for this same vehicle/years (i.e,. 91 - 02)? P.S. my apologizes if you've already answered this question, as I could not find a search feature of your comments. Thanks!
I have a '92 Toyota Corolla base model - the "fuel pump" is underneath the hood. The "Fuel Tank Gauge Sending Unit Float" is under the back seat inside the gas tank. Two different things.
@@PeterFinnTheCarDoctoris a good point of connection the hose coming into the regulator? Is there a fuel port connection on this engine like a Schrader valve ?
Help me Dr, I've been wrestling with this P0171 code for a few months. I also have had a weak start for a long time. I tried new MAF sensor and code returned, I tried numerous things and finally took to a shop that said MAF sensor. I told them a new one didn't fix and I asked about fuel pump, which the shop said wasn't it. I've got 185k miles on 2000 Corolla, and replaced the fuel filter around 150k. I don't like throwing parts to try and I can get a fuel gauge from Autozone. I don't understand how pumps can 'get weak.' The shop said they basically work or they don't. Same with MAF sensor, do these 'hot wire' kind degrade over time? Thoughts?
@@PeterFinnTheCarDoctor Nope, very good compression, I check not too long ago, I just picked u a pressure gauge to test and get data, I spoke to Denso this morning to check prior to simply replacing, we'll see. Thanks for response.
Did you fix the prob? If not check ling term fuel trims on a closed loop and see if the numbers are positibe and if you put it under load by idling up day 2500 rpm if the numbers ltft numbers go up. If they do its most likely fuel related. If the numbers go down its prib a vac leak
@@boohoo210 good catch, I had given up on testing pressure because my 2000 does not have an access port, so I set it aside instead of figuring out how to put something inline. Mean time, the fuel/performance was fine enough, but there was a acceleration/performance issue, mainly on steep inclines. I've tried fuel additives, etc and finally reviewed trims on my own and saw the massive drop in trims implying vac leak - spraying around proves nothing. I've been thinking injectors (was going to rebuild seals and clean and others say to just replace (but I don't buy ebay junk, 4 for $40, OEM is like $160/ea).

What if fuel pump is good, but not working because fuel pump relay or fuse or fuel pressure regulator is broken it no presence of gasoline will happen wright?
I have ae101 4afe when the car is cold the car runs very smoothly but after driving some kms the car loss power and strugling hard so the mechanic told me that the fuel pump is bad so what will you recommend
hi sir Peter,our car is toyota corolla 1.6 1992 what are the possible cause if the engine suddenly stop?we already check the fuel filter,clean the gas tank and we change the oil.but we did not actual test the fuel pump..and also it was all started when the check engine icon appear,until now when i start the engine,the check engine icon appear....thank you for your reply Sir!
my 93 corolla cranks but dont start do u think its a bad fuel pump or timing belt. i was driving on the highway n the car suddenly lost speed n die. but the check engine light came up right away now it cranks but. it does not start i changed the wires n distributor cap n spark plugs im gonna try to open that bolt u removed to c if gasoline comes out any ideas?
i have a 90 corolla. my car is trying to stall while under acceleration but doesnt (check engine light comes on for a split second then goes away) then wen i get to a stop light....wen i accelerate, itll stall completely.....u think thats fuel pump related?
avensis 97-02 7a-fe hesitates under low rpm acceleration and it doesnt show fuel level properly. could it be fuel tank assembly? that made me think. I havent checked voltage drop on the connector of the assembly but when I move the fuel level lever while testing for resistance - it doesnt show the proper ohms - thats a point towards semi-faulty fuel pump assembly. i was thinking of hooking a fuel pressure meter like chrisfix did in his vid
i have a Toyota corolla 1993 4afe engine manual trans but it drinks a lot og gasoline...my monitoring result is 1L is 7KMs only. i've changed already the fuel pump, fuel filter, air filter, spark plug. my last resort is the fuel injector to clean.
In corolla 98 there is pressure regulator in the pump. If this regulator is no working it can be too high fuel pressure and then too much fuel injected.
I have Toyota corolla 2002 the engine crank but won't start,I check the fuel pump is working,check the spark,change the relay for EFI but still not working I need any recommendations Peter

I've watch a lot of your videos and really like some of them but this video really tells you nothing about your fuel pressure, your fuel pump functionality and your fuel pressure regulator operation and what pressure it maintains. Pretty useless and misguiding for beginners. Not good.

Sorry Doctor but you have to put a gauge fuel pressure in the line to know il you have the good amount of pressure in psi.
What is the thread on it? I want to know which pressure gauge I should buy.
@@Shumayal For a gazoline engine the pressure should be around 40 to 50 psi. So a gaugue 0 to 100psi is correct.
Alldata says 38-44psi with regulator hose disconnected and 31-37psi with it connected
Thanks for sharing 👍
Is this a good way to relieve pressure for replacing fuel pump and filter?
Yes
a simple but effective test to see if fuel reaches the engine

Check your spark plugs. Are they white clean? Bad color is bad info.

Measure your pistons compression rates. Engine could be so worn out.

OR

There is one directly out the pump (inside the fuel tank).
