So at cold starts it starts fine but after warm up , it wants to turn over slow then finally it will pop off and fire. Its kinda like its vapor locking or the timings advanced to far, im at 10* base, and my voltage on my batt which iv tested several times before startup is around 11.9 and 13.4 idling.

Iv changed out my computer and went bcak to my 19lb injector setup, and still i get this proplem. IM wondering if this hasto do with my surging proplem on start up and sometimes at a stop light, any suggestions

 

CRANKING ISSUES are a result of either heat soak in your case or voltage drop due to a bad starter = high resistance in the windings or a bad cable or resistance at a transition point, such as the starter selonoid

 

that actually helps alot, thanks mjr.

Im running welding cable for my batt. relocation. It was used and had a few holes burnt in it, but i wraped and tape them up, maybe its that?

Also would a bad ground cause this, my selonoid is under my fender and im grounding my light harness off the same blot holding the seloniod on. might be that uh?

 

im having the same problem

 

I would use the proper cable, I had a simialar issue after my battery relocation, and I converted to a 92-95 style high torque mini starter and solved all the issue

do i just pick on up at autozone. And is there a cheap place i could just get the cable for the batt relocate?

 

dunno.....mine came with about 10 feet of it in my kit I bought but you'll need a bulk roll most likely to run it up front, any battery store should have such or boat/rv store

 

mines been doing it pretty bad lately

 

+1 on it likely being heat soak. My truck was doing it pretty badly until I had to replace the starter for a different reason. Turns over fine now.
