Ok, let me start of by saying I've never been mad that my car starts untill now haha.

So it's a 91 Z28 5.0 TPI and here is whats new: Fuel Pump, Injectors, plugs, wires, cap, rotor, CTS, and the fan switch in the head.

Heres my issue, a couple weeks ago it wouldn't start, and i was running late for work so i just hopped in my daily without looking at it. so every day since then it has fired up first try. now it did this before to me once but i figured it was old plugs and wires because it eventually started.

I have started it at least once every day and because it has started i haven't been able to diagnose it because well its starting. it seems to happen at random and it doesn't matter how many days it has been sitting because when it did it to me the car had only been sitting about 12 hours. Im really not sure where to go on this. I was thinking maybe the coil or the pickup is going bad.

there is no Security light on and no codes. and yes the lights work they test fine and fuel pump pimes as it should so I am at a loss as far as this is so any suggestions would be helpfull.

 

anyone?
