Have a friend turn the key for you and listen by the fuel tank to hear if the fuel pump comes 'on'. It you don;t hear anything... you know it's not working. Get the Haynes Manual and unconnect the fuel pump and use a simple (cheap) multimeter to measure voltage to make sure it's getting power, if it is, needs a new fuel pump. If it doesn't, you'd better check the fuse and relay. Sometimes the ignition switch itself is faulty.... the fuel pump is connected directly to the ignition switch, if it's not getting power. (There are two main grounds, one at the starter and the other at the battery/fuse box... make sure they are corrosion free.) Was the new ECU synched with the VIN and odometer loaded into the memory? If not, the pro didn't do it right and the vehicle will never start until it is.

check the tension of the drive belt for the alternator and replace any faulty bearing. Have a fuel pressure test done for the fuel pump problem.

Hi Rockandroll, Underground, or old timer? I think I would have the fuel filter replaced and have the fuel delivery of the pump checked. Once you've done that have the fuel rail pressure regulator checked too. Regards John

Well because you killed battery down you need to recharge battery with a good charger for an hour or two. You need enough amps to turn over starter & energize fuelpump. Just because starter turns over doesn't mean you have enough to power fuelpump. Before you connect battery charger disconnect battery cable while charging. This will clear stored codes. After charging, hook up battery see if codes return.

The most likely cause is a broken earth wire and or bad connection

check battery volts.should be 12.5 volts.if battery dead.your alternator is the problem.your car shut down lack of battery power.if battery good .check for spark at plugs.if yes.you got fuel problems.like fuel pump or pump relay.if you have no spark.problem in the ignition system.

Either you threw a belt or the alternator went bad. Your symptoms sound like alternator...you were running on the battery till you ran out of power.

I am having some issues with the fuel pump we suspect. The fuel pump is located in the fuel tank and occationally I can hear a motor running secondary to starting the diesel. As things have progessed i initial thought perhaps I had a hole in my muffler, but my mechanic has assured me that is not the case. The fuel pump may be a good place to start.
