Car won't start randomly
 

I have a '99 Camaro Z28 stock engine. Recently it has not been wanting to start. It cranks fine and once it starts it runs fine. At first this seemed to me like a loss of fuel pressure in the lines (cycle the fuel pump a couple times to get fuel back up to the engine), but now it is very random. It will sit over night and crank on the first try, then I will run into a gas station for 5 minutes and it takes 9 attempts to crank it.

Any ideas where to look first? I have to work all weekend, so i'm going to tear into it Monday, but I honestly have no clue where to start. Does this sound like a fuel problem or a spark issue? I really can't find any consistency as to when it starts and when it doesn't. It doesn't seem to matter how long it sits, whether then engine is at temp or not, or what the weather conditions are.

I'm not sure if this could be related, but my car has been throwing 2 EGR related codes for a couple months now. I have been mostly ignoring them because I'm about to put long tubes in and delete the EGR/AIR stuff.

Thanks for any help.

Did you replace the relay fuses it could be the Ignition relay fuse going bad

X2. I had the same problem on my '98. Wound up replacing the ignition relays under the hood, haven't had an issue since.

This same exact thing has been happening to me. Its been going on about 4 months now before and after I removed my egr/air in my 00 z28. Ill be watching this post. Hope yu get it figured out man

I'm going to replace them today and see what happens. I'll report back.

Thanks guys

mine was the ignition relay too

Ignition relay it is! $14 and I am back on the road. Thank you so much guys! It's a huge help when you guys point me straight to the problem.
