Re: [DML] Fuel Pump?

In order of ease in testing. 

Put a jumper across the RPM relay socket(brown wire to white-purple wire) and see if it starts (temporary). Don't leave it like this, the pump (if working) will run all the time. If it starts replace the RPM relay (very common fault).

Put a jumper around the inertia switch (temporary). If it starts replace the inertia switch. (Not common).

If it still doesn't go check for voltage at the pump with the RPM relay jumper in place. If you have voltage at the pump and it's not mkaing noise, replace the pump.

Tapped the inertia switch back in place, turned the key to "run", listened as the ubiquitous hum & relay-clicking stopped, flicked the key, and "vroom".... for about 2 seconds. Then nothing but spin. Got it to run about 15-20 seconds when I "primed" it, but would not keep going. Pulled an injector, tried starting again and no squirting fuel. Popped the engine-side line off accumulator, spun with same results. Pulled the center line off the fuel pump, spun, again, no squirting fuel. Hmmm. Do fuel pumps spontaneously die like that?  This is my 2nd, in use (well, not much) for ~18 yrs. Am I missing something, or is it time for a new pump?        Drive Stainless  (if it would start)      Robert   VIN 6924
