Multiple tries to start motor? I have a friend with a Camaro and it always takes him two to three tries before the car will start whenever it is cold. When the car is warm, it will usually start ont he first try. But when cold, it takes either two or three times turning it over for it to fire. Any ideas?
Car will not start n the first try when cold no matter how long you hold the key over. It just takes two to three times each time.

Yea, what he said. Fuel filters can definately cause this. That is the first and cheapest thing to try. If that does not fix it, check the fuel press. If the pump is going bad it can lose its' prime overnight and take a couple of times cranking to build up enough press.

the problem doesnt change at all when he allows the fuel pump to prime, even if he allows it to prime two or three times before trying to start it. Do you still think it is fuel related guys?
Might as well change that out anyway though..

Does he push the gas pedal at all when he does this when it's cold? If not try that. It's gonna be fuel/spark/air related. If pushing the pedal a little helps then he may want to drill out the little hole in the tb blade some or have a second look at the tune. Just start with the easy stuff then work your way up.

Can't hurt to check temp sensors (air, ect) with a multimeter. Check resistance when cold, then when warm, do it with key off so as not to set a code. Cold resistance should be high, low when warm. Check wiring too. Here is a generic temp/resistance chart off autozone for ect:

Swap the ignition relay with another one the same size and see if that fixes it. I had the exact same symptoms and that was my problem. Replaced the relay and haven't had an issue since.

just start with the easy stuff and check the battery and alternator. it's not fuel related if priming the pump several times doesnt help. batteries REALLY don't like cold, but how cold does it get on a cold day for you? if the battery is indeed in need of charging, this would be why. don't start randomly replacing parts until you've narrowed your problem down a bit

^^this. go to autozone, test your battery and alternator and hook your car to their scan tool all in one trip. as for the ECT reading -40, just about any car computer is programed to assume the coolant temperature is -40 if it loses the ECT sensor, which will cause the car to run rich to try to warm it up.
