    Help! My 2002 dakota 4.7 quit running while I was driving it. The instruments died at the same time. Used a code reader and found no codes. Have looked for loose connections, and bad fuses with no luck. Anybody got a clue where I should look next or what is most likely to be the problem. Oh, it cranks over fine, just won't fire.
    Thanks for any help!

    need to determine lack of fuel or lack of spark

    Try switching the Auto Shut Down relay with another similar relay in the fuse box.

    Did you put a fuel pressure tester on it? Can you hear the fuel pump pressurize the system?

    Had over 1/2 tank before it shut down. What puzzles me is what componet affects both spark and gauges?

    Where is the auto shut down located, can't find it called out on the lid of the box under the hood or the fuse block on the dash.

    prime it with silicone spray thru air intake while being cranked and see if there is a response....just because its in the tank does not mean its getting to the engine, can check for fuel pressure on rail too

    Yup just because you have half a tank don't mean maybe the fuel pump quit, would check all fuses related to the engine make sure they are not blown. If don't have gauges at same time it quit sounds electrical something in the ingnition maybe.
