my car was running fine until it wouldnt start. it will crank over but not ignite, i thought it was the plugs so i changed them. now it starts up but if i shut it off and try to start it again it wont. once i let it set/cool for a couple of minutes it starts back up again. when it is running it runs fine, i was having some trans problems also but now that seems to be ok now also. is it something electrical?

 

oh yea, its a 95 automatic z28

 

is there a check engine light on ?

 

no check engine light and no codes

 

Check your ICM. I had a problem where my car just died, then I would let the engine cool it would start right back up. The ICM doesn't like heat, but sadly it sits right on the cylinder head.

 

my car isnt dying though, it runs fine until i shut it off

 

i just seafoamed the car and it seems to have helped a bit but when i start it up it idles really rough for a minute or 2 and then it sounds like it clears it self out idles up to 1500 rpms and then settles back down to 8-900 and idles smoothly
