jdl 2/17/2014Are you saying the starter won't crank? If it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs and fuel pressure.
If no fuel pressure, check voltage and ground at the fuel pump wiring, engine cranking. When you first turn on the key, engine off, you should hear the fuel pump run for a few seconds.
Your electrical systems are all good? Battery has a full charge? The vehicle didn't go into theft lock?
HouseCallAuto 2/17/2014I need you to tell the full story from the beginning or aty least from the time everything was working ok and then the first thing you did and the time inbetween. All details. I get a lot out of hearing the story, it helps me diagnose what went wrong. No short assuming sentences please. Plug in a code reader and give me fault codes too.
AutoMD Member 2/20/2014check the wiring of the fuel pump relay. change it if need be.
