My Sonoma truck just quit running while I was driving it. I replaced the fuel filter and fuel pump. Man, taking the bed off the truck is a lot easier then pulling a fuel tank with gas in it. I have no codes using a Black and Decker code analyzer. I get a no code and a green light. I determine that spark plugs are sparking. I just don’t have fuel to the engine. Help me please.

Do you hear the fuel pump come on? If so check the fuel pressure and also for injection pulses. If not could be the fuse and fuel pump relay.

Rasmataz,

i checked the fuse and the relay switch, they are all fine. I can hear the pump start up with the key is truned on. I do not have any testing equipment for pressure testing. Guess my next move is to find someone in Oklahoma with the testing equipment. Thanks
