See if your fuel pump comes on if you jumper pins 3 to 5 of the fuel pump relay socket. That connects the fuel pump fuse 6 to the fuel pump. The pump should come on even if the key is off.

Morning PJ Gerstenberger

I'm still thinking it could be the kill switch part of the starter button. ---You have already done that when you posted above " I get 12v at terminal 87 (probably 85) when I push the starter button". If the kill switch wasn't working you would not get any 12v to starter relay showing when you pushed the starter button.



Could be different cause for each problem. I'm still looking for a way to trouble shoot the kill switch
portion of the starter button. It may still be involved.
-- I'm pretty certain that you have separate problems with the starter & fuel issue but you need to sort one or the other first then move on to the other one. They could have a root connection but get the starter working from the push button THEN move on to troubleshooting the fuel pump issue (once the starter circuitry is operating OK that eliminates some of the fueling circuitry as being the cause).

Morning PJ Gerstenberger

Too many posters going different directions on this & that will confuse your troubleshooting issue so I will back out of this thread & let Jim & Roger work with you on this.

If you need anything specific that I can help you with just PM me.

Of course. You're right. Silly me. I should have realized that
12 volts while thumbing the starter button eliminates the switch as a problem.
Thank you dirtrider. I'll get the starter sorted and see where I wind up.

Good evening folks.....

Starter relay fixed the no starter problem. Spins fine now when I thumb the switch. Still no fuel pump.
Fuel pump does engage when I jump 3 & 5 of the fuel pump relay socket. Very close to solving this.
Thoughts?

Okay, lets look at three possibilities in order: fuel pump relay circuit, the Motronic relay circuit, and then (hopefully not) the Motronic.

The next thing to check is the fuel pump relay. Test your horn and if it works, swap the horn relay into the fuel pump relay socket.

If that works, you need a new fuel pump relay, if it doesn’t, you’ll need to make a voltage measurement that I’ll post in a moment.

Horn works...Already did the relay swap. No change.
Curious as to the voltage test.

Try swapping the horn and Motronic relays. Will be back to you on the voltage test.

Turn your FP relay upside down and find pins 1 & 2. Measure the socket pin associated with relay pin 2. You should have 12v on that pin when the key is on. If you don’t, try pin 1 and see if it has 12v with the key on.
