1991 RS V6 Won't Start Cold - Starts Hot
Can this be a Ing. Coil causing this, hard starting cold but once you get it started and warm it starts ok, I've been suffering a stalling problem also when cracking the throttle.

Re: 1991 RS V6 Won't Start Cold - Starts Hot
So I started out this morning checking CTS and found it was right in the the resistance range no prob. with it but I did find that the voltage comming to it was 4v and should have been 5v, put on a new coil tried to start cold and no change, drained fuel and put 5 gal. premium chevron no change still. Leaves me to think only two things possible left fuel pressure reg. or the ECM/Chip. let you know. Thanks again, George. Checked fuel pressure first OK 42psi.

I Have the exact opposite, my car starts right up in the mornings but drive it 10 miles til it warms up good and shut it off and it wont start again til it cools off hours later, and yes when i crack the throttle it will stall and wont start again til it cools off.. its not an overheating problem, temps are good.
New ECM. well not brand new, barly 2 years old but let GM buy it and install it with new insterment cluster and various sensors.
