Re: 1990 lumina stalls when hot

There's 3 coil packs, one ignition module mounted under them....the other likely culprit is the crank position sensor.

In the shop we used to do 'em both if the customer would go for it...they have a fairly similar service life, it seems.

If yours has the CPS on the front of the engine, make sure the wiring is not rubbing the crank pulley...
