88 TBI no spark/no fuel

ok folks....ive got my baby here. ive owned this car for 14 years.. but anyways she's been parked for the last 2 years and ran fine when parked. cranks good, fuel pump kicks on and fuel pressure but no pulse from injectors or spark. ive done all the basics i can think of, ICM,Coil,Cap,Wires, grounds, checked wires for cuts or mice chewed,even changed the ecm with a spare i had. everything checks out as i can see and no change in condition. probably be something stupid and hopefully someone can point me in the right direction. i would probably stumble across the problem but i dont have a garage or the spare time to fumble with it for a weekend at the moment. ive gotta get this thing moved. any helps appreciated. thanks

The one thing I noticed missing from your list was fuses . There is one on the fender near the charcoal can which powers the ECM (and thus the injectors) but I didn't think that one also did spark . Also fusable links from the main +12V terminal on the starter that power several different circuits . Could one of those have gone open ?

Re: 88 TBI no spark/no fuel

I see your list includes coil, is that the ignition coil, or the pickup coil?

Cool, glad you were able to fix it. I was pretty sure that was the problem, I think the only things in 88 that would keep the injectors from pulsing is either no RPM signal (pickup coil) or a bad ECM.
