i'm stumped on my 95 cobra dilema. the car starts fine and runs awesome when cold. once it warms up it will start if you turn off and then start quickly. but if it sits for a couple of minutes...no start. it acts like the coil is disconnected, cranks strong, but will not turn over. has new MSD dist., coil, battery, alternator, 225 lph fuel pump. i've checked ignition control module and it passed three times. please help before i drive it off a cliff.

Could be the pickup in the dizzy. Was it replaced because of this problem? If so, I'd try a new TFI (ignition control) anyway. I've heard of them failing intermittantly, but mine went all at once.

When it is not starting, do you have fuel or spark? Get it to not start, and pull a plug wire, use a spark tester, or better yet a spark tester and see if it sparks. At the same time, hook up a fuel pressure gauge and see if you get fuel.

well, this is what i went ahead and did. my timing was advanced to about 18 deg., so i bumped it back down to about 12 deg. this seemed to fix it i think. i let it idle in the driveway until thermostat opened, cut it off and came back about 10 minutes later and it started right up. but i wouldn't think that advanced timing would make it do that. it was not pinging or anything. i really dont want to drive it anywhere right now because i don't want it to take another crap on me. anyone with 95 cobra or GT...could you please post your timing deg. thanks...

Your timing was too advanced.

Check the IAC. Had same problem when my car warmed up. Remove it and make sure the ball moves side to size with ease. Also while you're there spray some carb cleaner and remove the carbon buildup.

Also, the '94 and '95 harmonic balancers are prone to failure - they slip, and result in an erronious timing reading. Overadvanced timing will cause a slowcrank (like the battery is weak) condition when hot.

appreciate all the help. i think its back to par. not to sound like a dumbass, but what is the IAC? i'm having trouble with that abrev. i fiqured that i'd check before i go cruising and it takes another crap on me. thanks again...

Idle air control valve, its bolted to the throttle body facing the front of the car.

18* is way up there, I keep mine about 12 so I don't have to run premium.
