42 Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles
The truck ran a few days ago but it was hard to start. Now it wont start. I dont hear the fuel pump pushing gas. I was suggested to checking, and replacing, the Automatic Shut Down (ASD) Relay. This is what sends power to the fuel pump and it is not uncommon for it to go bad. It is a lot cheaper and easier to replace the ASD relay than the fuel pump. I was told to the the splicing of these wires under the relay box get corroded and needs to be re soldered together. What else can I check. I was switch relays around I think thats why I got code 33. I'm going to take my relays to be tested then move from there.I have no fuel pressure.
have the same problem?
