1985 Firebird starts when it wants too.
My neighbor has a 1985 Pontiac Firebird V6 2.8L. Sometimes it wont start. He had it in the "mom and pop" garage and they hooked it up to an analyzer but it didn't show any codes and they said they couldn't find anything wrong. Of course it started right up for them after it was towed there. It has been starting for a couple of weeks but today he drove into town and when he got in to come home....wouldn't start again.
If this is happening when the engine is fully warmed up the first suspect is the ignition control module in the distributor. They can be sneaky and work fine when cold but as soon as they get warm/hot break down and fail causing a no spark condition. Same is true for the ignition coil. When it refuses to start check for spark. Try spraying some starting fluid down the throttle body. It should run a few seconds on the starting fluid. If not it's an ignition (no spark) problem. If it does, it's a fuel problem. HTH. -Jim
Js is right, those were notorious for ignition modules and distributor pickup coils going into thermal breakdown.
