3800 intermittent no start

[Exgmguy]

This not my week. My beater 1990 Buick Lesabre has been a very reliable car. A few days ago it developed an intermittent no start problem. When it is cold, it starts fine. After I drive it for a while it will not start back up. No spark. I have to let it sit for 20 minutes and it starts right back up.

I did some Googling and this appears to be fairly common. Most people say to check the crank sensor, then the ignition module, then look for bad grounds. I have replaced the CPS, and the module, and it is still happening.

Any input would be hella-sweet.

Fuel Pump test for pressure. Alot of times the pump rela and wiring will burn up.

a friend of mines old Grand Am would do the same thing, it ended up being a bad ground somewhere in the car...

does it have coilpacks?

or a coil?

It does have coil packs. I am assuming that it is going to be a bad ground. Now I just have to find out where the hell the grounds are at. I think I can bet that it will be somewhere that sees weather, or under carpet or something.
