I have had enough with these headers. I put a new starter in because I was having starting issue, which now I am thinking was heat soak. First start up I never had an issue even now. After car is hot and let to sit it would have trouble starting. Then I decided to put in mini high torque starter and wrap the solenoid now when it really hot out currently 84 and humid it started up just fine ran to get gas came home, let it sit for awhile and it would just click and starter wouldn't engage. I have 12.6 volts to the battery I tried to cool starter down with cold water, tap on starter and still nothing? Please help...

 

Maybe the wire going from starter to your battery is corroded and not making good connection... try jiggling it on both ends (Starter and battery side)

 

I just installed starter like 3 weeks ago and I cleaned everything. it starts once everything cools down.

 

Well in that case it might be your ecm. I have heard of some peoples computers causing similar issues, just google stuff like "Tpi car wont start agin after driving awhile" And read up until someone more knowledgeable can help you, but sounds like ecm to me.

 

ok thnks ill look into it

 

Hey man I bet your issue is the ICM, sometimes they will create similar issues like your having and the ECM sounds less likely ( Small chance) after I thought about what you described. A new ICM is like $12 and it just sits under the distributer on some models... It could also be your Coil (If you have one)

 

I just had this issue. Car starts up, drive it, wont start unless I let it sit for a bit. Turned out the be the ICM chip. But the car WOULD turn over, just not run. If it its doing nothing, it could be a heat issue.
Long story short, I had a hood lock and start kill key switch installed back in 1990. If the car was hot, it would not start. Turned out the wire that killed the starter was NOT big enough and it would get hot. I since cut that out the following summer and the issue was resolved. If any wires are getting hot, that will build up resistance and cause current to fail. Maybe the headers are heating the iginition wires?

 

sounds like the wires, maybe wrap them all in heat tape?

 

Ill check ICM tho, it just seems like starter bc that is the only thing I have been messing with.

 

Sounds like a timing issue to me. My Vortec starter cranks my 350 over fine at 12* initial timing.

 

I would for sure. Can't hurt either way. Are the headers wrapped?

 

.

Well if you could somehow run a jumper wire from the battery after its hot that would confirm if the wires getting hot are the issue.

 

no they aren't, I don't want them to rust any faster then they are prolly going to anyway

 

yeah ill have to start messing with it, im just losing interest, after I fix something something else needs to be done lol
