No fuel from TBI injectors-92' 4.3

[Hudgins]

My truck has a sparatic problem were it won't start. If it sets 1-2 days it will start. The engine cranks, but will not start. Fuel pump is less than a year old and I have verified that I'm getting fuel at the connection at the TBI. There is no fuel coming out of the injectors. My next guess would be the fuel regulator, but I don't have troubles with the truck dying while I'm driving. I am only recieving .8 VDC at the TBI injector connecter. This doesn't sound like enough Volts to fire the injector. Could I have a ECM problem? Before I descovered the fuel problem, I replaced the Plugs, wires, Distributor cap and rotor, and ignition Coil. Pick-up coil was replaced 1 year ago. Please help, I have been fighting this for months.

when you get it running again tap on the ecm with the blunt end of a screwdriver, if it stalls thats your problem.

Thanks, I'll try if I ever get it started again. I have verified the fuel is making it through the regulator. But still no fuel goming out of the injectors. I have also discovered there is no spark at my spark plug. I had my ingition mod. tested and it is good. This has to be an ECM problem. Anyone have any other suggestions?

I found the fix. When I discovered I wasn't getting spark (as well as fuel) I knew it had to be ECM or Ignition switch. I replaced the ingnition switch for $11 and that worked. I'm back on the road.....
