Yes I heard the fuel pump turn on. Is there a test for fuel pressure that does not involve a gauge?
Jim
Thank you for the quick responses, but I have to leave for awhile.

No. Fuel injectors can be real finicky if they don't have enough pressure to fire correctly. So a pump could still push fuel to the fuel rail and actually squirt out the test port, but not enough to push through the small holes in the injectors.

Could be crank sensor or ICM. It is possible to remove the ICM and take it to autozone. They can test it, but, usually when they fail, is when they are hot.

Temperature gauge said it wasn't completely warm, and the high Friday was about 15 degrees. So I will try to do the tests on the crank sensor. Do you still need an alignment tool, I haven't done one since my 86 delta 88.

Remove the spark plug wires, then remove the 3 coil packs. That metal plate with the metal tangs is your ICM(ignition control module)
