Fuel Pump wont work DME

[ErVikingo]

OK Guys,

I give up, I've replaced the fuse, the front compartment relay and the dme relay but the still won't turn (last two just received yesterday from Pelican !).

How do I test the pump itself?

FYI, this is on my 78 that has a 86 3,2 transplant.

TIA, Juan

Ideas?

Do you have a Bentley? 201-10

Make a long jumper wire with a SPST switch in the middle & a fuse. Remove DME & one end of jumper goes to DME socket 30 & the other to socket 87b. Make the jumper long enough so you can lay under the car & hear the pump come on or not. Ignition does not have to be on.

I do (a book that is ) but I have not looked for a solution to my problem in there yet (I was hoping one of you guys would have a quick answer based on experience).

I'll try the jumper as suggested and will report back.

THANKS !!!!!!!!!!!

Yup. My fuel pump died as I was accelerating onto a freeway. I had the car flat-bedded home & bought a relay. No go. I did the jumper & my fuel pump just clicked but didn't run. It was seized. It's not hard to replace.

I had a similar problem before which "necesitated" the replacement of the DME unit.

Now the car has been sitting for some time and I'm thinking if humidity perhaps affected the contacts or the winding of the pump. I originally thought of gumming up of the pump due to old fuel but since it never ran when I tried to start it....... (not sure about your pump but mine you could hear when you put the switch on the "on" position - perhaps a sign of inminent failure).

Thanks again Ian, your help is most appreciated !
