1994 Chevy Suburban V8 Four Wheel Drive Automatic

My truck started to die, with no power when pushing on the gas pedal, and eventually shut off. I replaced the fuel tank sending unit and pump, replaced the fuel filter. And I still can't get the truck to start. What could be wrong?

If you're getting spark from the ignition check the fuel pressure make sure its within specs. And check for injection pulses from the injectors

Our '94 Suburban was doing the same thing.
It'd start, but then intermittently lose power while accelerating, eventually leading to a stall. Then it wouldn't even start.
We had a new fuel filter, fuel pump installed. Still did the same thing.

Had a friend (who's a good mechanic) look at it.
He immediately diagnosed that the COIL was bad.
Went to the local auto parts store and bought a new coil. He replace it and *Vroom*.... the Suburban started right up, no prob. And...no loss of power while accelerating.

For what it's worth...check your coil...or replace and see what happens.
