Heat soaking starter with shorty headers?

I have hot start issues, but I'm not convinced it's just the injectors. When it's hot, I'll turn the motor over, and it will crank fast for a few seconds, then it will crank real slow, almost like I have a weak battery, then it will fire up fine after a few seconds. I think if it was the injectors, it would crank at the same speed all the time. :shrug: I know longtube guys have problems with their starter being heat soaked. Is this possible with shorty headers?

Chris, if it does this like clockwork, I would put a jumper battery on your battery and crank it. If it cranks goofy, like it does now, you can probably rule out the battery (I know you have gone over grounds and whatnot lately).

Good luck bud.
 
I know the battery is weak, but it will crank just fine 80% of the time, except for when the motor is hot. Even sometimes when the motor's hot, it will crank right up. The battery seems to have good cranking power.

JT, my dad has a booster pack at his shop, I'll see if I can hook it up next week sometime to see what happens.

Brad, I don't think the starter is going bad. It JUST started this after my heads/cam. So I think maybe the headers are just giving off a lot of heat maybe. The engine bay is always blazing hot now whenever I pop the hood.
 
IMO its probably more the battery than the starter. I don't know if u have the high torque starter, but I've been told they can absord a lot of heat before having problems. Also if the battery is weak, it may give one or two starts when cold, but will weaken after that if not fully recharged.
 
Chris,

I'd be having the battery checked. Had a '72 Merc Capri that I swapped a 2.6L V6 with headers into (was originally a 2.0L 4cyl), and immediately started having similar problems. Turned out the battery had a dead cell in it, would crank the 4 just fine, but the added strain of the extra cylinders was too much for the starter load on the batt.
Best of luck,

Kerry
 
Well My car does the same thing starts fine but once its hot and i turn the car off its like the car is dead and either it just clicks or just turns over but its having a really hard time doing it.. I Installed Thermal Wrap just the other day Thinking that might fix my problem But i was wrong.. Im going to replace the Batt. Just to be safe anyways and during the winter while the car sits im going to install a Hi Tq Mini Starter. Ill only drive the car if i know ill be somewhere for a while so the car will start. if not ill take my everyday car then

I have always thought that our 94-95 Stangs came with the high torque starter :shrug:

Can anybody confirm this one way or the other :D

I assume Grady to be correct (though I have not explicitly seen that). The foxes got OEM higher torque versions in late '92+, so it would seem to reason that this was for a reason for this (Ford does not spend money for nothin) and would continue it.

I can tell you the starter on the '94 sounds way way different than the OEM-style one on the '88 (the latter is a whiny crappy sounding one).
