1991 Trans Am 5.0 TPI No Start, No Fuel
I’m not getting any fuel to the engine, the strange thing is that the Service Engine Soon light flashes on once about every 2-3 seconds, the cooling fan turns off and on with the flashing of the SES light. When I jumper the DLC to check for codes, the SES light flashes like I didn’t even jump terminals A & B, so I get no codes, not even the normal 12. It will run if I constantly spray it with starting fluid.

Sounds like the ecm could be faulty. Does the ecm still provide a 2 sec prime of the fuel pump ?
