94 FORMULA was cutting out , read not sputtering ,fully cutting off. Then hard to start. This got worse now it would start at all . Now No crank with 12.5V and a jumper box. I can hear the fuel pump run. So far the guesses are key and ignition, fuel pump and of course optispark.. The car has awesome power and idles good while running. No antifreeze smell. Checked all the vacume lines and the oil is good.

Does your security light come on when you turn the key on? Then go off after several seconds. If security light stays on then starter & fuel injectors are disabled. If no security light comes on when key turned on, you need to fix the security light.

Good security write up at www.shbox.com

You need to attach an obd 1 scanner to aldl and scan for codes. The 3 ignition biggie codes don't light the check engine light. But will keep engine from running.

You also need to get a fuel injection pressure tester. Attach to schrader valve on fuel rail. Turn key on, pressure should be around 43 psi.

You can also remove your icm & take it to an auto parts store for testing. Be sure to put thermo paste on back of icm & it's heat sink, when you install icm.
