Corvette Start Issue Solved: Loose Relay Connection
HTML-код
- Опубликовано: 11 июл 2024
- UPDATE: This ended up being a loose socket for the crank relay... I was having another starting issue just before this one. And while troubleshooting for that issue, I used a multimeter probe in that crank relay socket.
Doing that spread open the leads, and caused this problem.

It Took basically two years for me to solve this coupled with the 2005 "service steering column lock" problem. I solved the latter problem with the cheap ebay dummy load plug in. But about one year after installing that the error codes returned and the no start issue became more and more frequent to the point the car was too unreliable to drive. Got pissed and finally figured it out. Open your fuse box under the hood. Pull relay #43 out. Mine is the original AC Delco unit. It has 4 short posts that plug into the fuse box. Pry the grey cover off of the relay. Then carefully with the car in neutral and E brake on plug it back into the fuse box without squeezing the relay contact shut. Go ahead and push the relay contact shut manually and your starter will turn the engine over. The starter will engage and try to start your car. In order for the engine to fire the rocker start switch on the dash has to be glowing green on top. Solder a wire to each side of the relay and attach a simple push switch. This by-pass will turn the starter over regardless of whether the ignition is on, regardless of the clutch being depressed or not or whether it is in reverse, 1st, 2nd etc.... Be careful but if you do it the no start issue will be resolved once and for all. Btw, I still get "service column lock errors" on the display... I ignore it. I can now drive without worrying about turning the car off without starting back up. PROBLEM SOLVED.
thats just a pin fitment issue on the underside of the fuse block. its got nothing to do with the relay its the female side of the terminals having poor contact to the pins on the ignition signal wire or a issue before that part of the starting circuit. your a moron for suggesting someone does this you realize someone can get killed doing this correct? thats why there are clutch switches and neutral safety switches. and fuses lmao if your gonna instruct someone to do this at least mention how to make it safe you just suggested someone makes there car able to move at any given moment if that buttons pushed while cars in gear. good advice for a friend in need of a quick fix but not for the general public
Can you make a video how to fix
please make a video
Why didn't you just swap the relay?
Guys it could be one of these few things. Relay, fuel pump, battery or alternator, and if that’s not it, could be the sensors or the starter. But personally, my problem was my Linkage on my shift cable. If this is happening to you, try to start the car is a different gear, if you’re in an automatic, start it in Neutral for example. It worked for me. Hope this helps!!
I’m having the same issues on my 2006 manual. You say that it could be the linkage on the shift cable, I thought they only had that in automatics? I’ve been going down the list myself to solve this issue for mines. Where is that shift linkage cable located?
For me it was my battery, I was getting good voltage around 10-12 that it marked but the car just had a tick when I pressed the start button, all the lights turned on and everything it seemed like it wasn’t the battery at all but after I jumped cables it started right away
What's proper name for headlights
Hey I’ve been looking for the clutch start sensor and was wondering if you could send a part number or a link, I’ve been struggling to find one. Thanks!
That’s something I go straight to the dealer for.
DID U CHECK RESISTANCE IN THE STARTER WIRES...ALTERNATOR TO STARTER AND THEN STARTER TO BATTERY...ALSO CHECK THE LUG ON YOUR STARTER IT NEEDS TO BE CLEAN AND TIGHT THATS MY OPINION I HOPE THIS HELPS U
Thank your for the advice! I did check everything, several times. It was that relay socket, as the car has been fine since then. (Good for about 2 years now)
Thank you though!
Where is the crank relay located? You just tightened it?
The crank relay is inside the under hood fuse box. It removed the fuse box, disassembled it, and bent the metal prongs which hold the relay in place, so that they would hold the relay better.
I only had to do this, as I had bent them outward, like an idiot, when I stuck my multimeter leads in the relay socket, while troubleshooting an different issue.
I was having a different starting issue before this one. It was either the starter or the clutch position sensor. I’m not sure which, as I changed them both.
Thanks!
@@CliffsHowTo what number is the crank relay
It may be a ground wire check the wire till you transmission for a reverse
I have a c5 that does the exact opposite. No start when cold, but starts perfectly when temperatures are warm. I’ve replaced battery and starter but to no avail. Anyone have experience with this?
take it to a shop youve already wasted 300 dollars :)
Same here I’m having a starting problem with my c5 I turn the key no sounds or anything brand new battery although I accidentally ran it down alil the day I got it I left the drl lights on although my drls actually are disconnected and don’t work lol the dash odometer was on the whole night went out no start but it starts every so often like today this morning started first try cold then drove it for an hour got gas turned on perfect went to my gfs for a few hours she left I tried to start my car nothin waited an hour and half fartin around tried to crack 20+ times nothing then one random try after 3 more and boom my batter on dash was sitting at 12.2 volts idk what’s goin on idk if it’s the ignition starter alternator or battery I’m goin crazy
@@coltonscutlery6919 So it ended up being my ignition switch. I don’t even want to discuss the headache my local dealership gave me… they couldn’t diagnose and charged me for unnecessary work and ended up saying “were no longer going to work on your vehicle”.
I ordered the part from rock auto and replaced it myself.
@@freescotty3948 damn dealerships bro absolutely ridiculous
@@freescotty3948dealership did me the say way except they also towed my car away to a tow lot while I was waiting to hear from them...I bought a new ignition switch and installed. Did u get a green or any lights on e installed
So did you fix it? If so what was the fix?
It is fixed. I am not sure what the original issue was. It was either the starter, or the clutch pedal sensor.
After changing both of those, I was still having the no start issue, but only after the car warmed up. The relay socket was expanding with heat, and allowing for enough space for there electrical connection to not work.
Once I tightened up the relay socket, I’ve not had an issue with the starting.
I really wish I knew what the original issue was!
Where is the relay socket? How did you tighten it?
@@JayJay-eo6gd The relay pins r in the fuse box underneath the crank relay...U get a pick and open the terminal for a better contact that's tightened
@@reneegonzalez6064 you are beautiful
@@reneegonzalez6064 do you mean pull the relay out and then take a pic please walk me thru this when you say pic ??
Been dealing with similar bs for a while, finally ran a new 0awg line directly to starter and worked, but today car was running odd ans litterly shut off while driving then back on.. would not crank no matter what i did.. everything relating has been changed except the bcm, fuse block area..thays my next step, what a amazing car but a pos at the same time.. ridiculous what they sell these cars for new,
So what exactly was it? Can you tell me what part, mines doing same thing
I explain in the video. Relay socket was loose.
@@CliffsHowTo which socket? Thanks
I have the exact same problem with my 07 the exact same. I started having this problem when I fixed the shift cable. It's gotta have something to do with the shifter or the sensors it affects.
Mine was a loose relay socket. (I opened up the contacts by inserting a multimeter probe, while trying to troubleshoot the starter…)
My 05 c6 has the same problem kind of , but the only gauge that comes on is the voltage meter. After that nothing, no start, no nothing, it’s been that way for two weeks now. Service column lock. I bought two column lock bypass’s and still the same nothing. I tried disconnecting the battery and it still the same. I’m at a total loss of what to do .
Aw man. I don’t know what to tell you about that one. I wish you luck!
I'm having the same issue .. bcm is the problem hope you fixed yours already
@@panzerwaffen2873 did you fix your problem with yours? What did you do to fix it?
@@javfernandez4695 yes I did fix it thanks to a good friend of mine ..it was a burnt wire that goes from the bcm to the driver side ...just one simple wire dominates the whole car
@@panzerwaffen2873 any idea where to start looking? I know that the bcm is under the passenger floor carpet do you know which connector that wire that was burned belonged to?
My problem was fuel pump RELAY fuse #55 in the fuse box
If not, definitely the fuel pump
I've been having a similar problem with mine. Except mine turns over super slow and sometimes it'll crank and throw the p0335 and p0336 codes and tach won't work and runs like garbage. Already replaced the crankshaft sensor and it was a pain to get to. Hoping I can go thru my relay box and check all my connections. It's pretty embarrassing to stop for fuel and the car does this and I have to disconnect battery to reset computer and wait for it to cool down. Fingers crossed its something simple like a bad fuse connection.
crankshaft relearn.. lmao cars probably firing against itself when your cranking it cause it doesnt know where the crankshaft is in its rotation
@@justing9902 it hasn't done it in a while but still turns over slow after its at normal operating temperature. My buddies does the same thing. Maybe the headers are getting starter solenoid too hot. Starters a pain to replace too. Same place as crank sensor pretty much.
@@calebfreeman9361 put a test light on the starter end of the battery power feed when its hot and wiggle the cable i bet the light will go dimmer and brighter when its hot haha cables probably got corrosion inside the rubber loom
@@calebfreeman9361 starters can handle a ton of heat thats some kinda issue with the starters power feed
good evening my C7 is having this exact same issue and I can't seem to find a fix, did you ever find a solution?
Did you ever find out the problem? My C6 does the same exact thing.
Check the relay on the passenger side...there a box that comes down on the foot panel...my car is a c6 z06 not sure if it's the same on a c6
Did it work?
I havent tried it. I took it to the dealership replaced the column lock and now after it warms up; you drive it, and park for a hour or 2 its will not start.
i am having same problem with my c6 .. i took it to the dealership they charged me 700 dollars to change the automatic shifter and it still doing same thing i ordered a new starter i hope that will fix it ..... did u ever find out your problem
Yes.. on my 2005 C6.. Its a relay that tells the computer to retract column lock pin to unlock the steering wheel to start the car. You can hear it when you push start the car at start up. There is no recall on the issue so the dealer has to fix it cost around $600-700 with labor. Once you get it functioning properly you will need to purchase a column lock bypass module (Corvette of Houston) or couple other places and sites sell them $75-100 that installs behind the dash tachometer display. It bypass the security feature to extend the pin to lock steering column and tells the car not to lock the steering wheel. You should be good to go.
I'm having the same problem, lve changed the battery, the starter and that helped for a bit but now l can't get the car on, l just changed the ignition switch and still nothing
I had the same problem...it took me months to find it but I think I did..theres a relay in the passenger side, foot panel, I change mine and it work good after that..
Adi Leon what relay did you change ? My car is doing the same it won’t turn on
On my z06 theres only one relay is black number is 3602
@@adileneyfranky so the fusebox in passenger side not the one in the hood ?
wakanda both
Where is the crank relay?
Under hood fuse box. Near the battery.
Try and wiggle your starter relay try it then remove relay n put it back and see it could just be bad connection
Then swap it out with another one thats similar like??? Ac compressor?? Just swap the 2 n see if the problem moves

Yeah, for me, it was the relay pins. I used a multimeter and hat was too big in the slot. It spread the pins just enough so that when the relay pins would heat up, they would not have a good connection.
I think the starter was the original issue though.
Looks like bad ground
Similar. Relay socket was not making a tight connection.
Am I the only one who thinks it’s starting perfectly fine ☠️
It is in this video. I was showing that I had found/fixed the issue.
All the relays with diodes are giving people hell. start relay and ignitition relay should be replaced
My 2 Cents
I just replaced my entire UBEC/under hood fuse block. The car was good for about 4 years, then started doing it again a few weeks ago.
