Ok, so I have a 00 GT. On Saturday, the car would turn and fire and immediately shut off. I checked the vacuum lines and replaced a cracked hose.

So, we tried starting it again and it would turn, fire, start and die. So I cleaned the IAC. Went to try to start it again, and it won't even start anymore. My theory at the time is that we drained the battery from all of the previous starts (alternator couldn't recharge the battery).

Fast forward to Sunday. Car won't start at all still. So I take the battery from my Cobra, which is good, and put it in the GT. Nothing. So I jumped the battery and the motor SLOWLY turned over but did not fire. So I immediately put that battery back in my Cobra and it started right up.

So I have my head all confused because I can't distinguish if I have two problems or one.

Things I've tried:

Rechecked the alternator - It's Good
Checked Vacuum - Good
Checked battery - Good
Cleaned IAC - Done
Checked MAF - Done
Cleaned TB - Done

Punched a hole in the wall - Done. (Need an estimate for repair) lol jk.

If you have input, let me know, thanks.

PS:

One other question, do I need to have the motor turn over in order to check spark? Or is there current through the wire with just the key on?

Check the battery cables or possibly the starter?

^ yes you have to turn the motor over to check spark. have you checked you spark plugs to make sure that you havent fouled them out with all the cranking?

i'd be doin' some voltage drops on the starter cables. also, visually check the cables. is it a no crank situation now?

have you cleaned the battery posts and terminals? How about the ground cable where it attached to the engine? Yes, you need to be able to turn the engine over to check for spark. I just had a these problem on my truck.

i would do voltage drop on the battery terminals and wires to the starter

Sorry for the delay in reply. I actually didn't have to check the starter wires or do any voltage drops in any of the circuits.

Even though I cleaned the IAC, it turned out to be the IAC. I had to buy a new one though. Usually, you can just clean those out and it works but I guess I was wrong this time...
