93 k2500 4 X 4 with TBI problem

slavio · 11-22-2005, 10:37 AM

I have a 93 2500 4 X 4 truck with a plow on it..........it had a 350 in it and i pulled it out because it was really worn down with 370 000klms on it. i bought a crate engine 305 and put it in with everything hooked ready to go.
The engine turns over the fuel pump presurizes and there is fuel at the throttle body just before the two injectors. when it turns over there is no fuel spittin out of the two fuel injectors. when fuel from a bottle is thrown in the throttle body it starts for a second. ive come down to that there is no pulsating at the injectors.
My question to u experts out there how do i determine whether it is electrical or whether it is the injectors. PLEASE help as i want my truck running
IF YOU have any suggestions please offer if the suggestions are about electrical components please explain carefully as im not really good with a voltmeter or other electrical things.
THANX

Check fuel pressure. Could be a regulator, Thats a start.

Could also be faulty injectors, before you jump to this conclusion though make sure you have everything hooked up. Is your wiring for your injectors and everything else hooked up?
