2000 gmc fuel problems
 

Just purchased a 2000 gmc 1 ton old body style, 350. i am not getteing fuel to the engine. i have checked the fuel filter its great, fuel pump was pumping fuel through the lines. I have plenty of fuel to the engine, i opened a vavle that looked like a a valve stembehind the throttle body and fuel shot out. engine fires on carb cleaner and then dies right away. any ideas?

you need to find out the fuel pressure...it takes about 53psi for the engine to bust....screw a gauge to that schrader valve...I bet she's too low.
30 will shoot a stream across the shop...but not kick off the engine

invest in a noide light and plug it into the injector wires it lights up if you have injector pulse if you still have no fuel go for the injectors
