1987 2.9 won’t start

[bborland]

New battery , new ignition coil, new fuel pump relay.

relay is not turning on so no fuel pump.

Checked voltage at relay and high fuel pressure pump , only getting 2.3volts with multimeter.

any help would be appreciated on where to go from here , I’ll attach photo of where fuel pump relay plugs into harness. Looks a little fried to me ?

I'd try the fuel pump relay bypass to see if you can get the fuel pump running. If that works, I would suspect the EEC power relay (which supplies power to the positive side of the fuel pump relay coil) or the ECM/computer, which controls the fuel pump relay. I've attached a couple pics that may help.

Thank you Paulos , you were right,it was the EEC power relay. We are all set and running again. I appreciate it , take care

You're welcome. I'm glad it was a relatively simple/inexpensive fix. ECM's aren't cheap.

This should be a Sticky note. Good Stuff. I did it just to see it work. Thanks Paulos
