89 RRC, no power to anything fuel.

I'm an electrical retard so I need some serious help here.

I'm trying to get my 89 RRC project running. The problem is I can't get any power to anything fuel. No power to, inertia switch, relay, fuse or pump. Any suggestions on what to try?

I've changed the fuel pump relay
Shorted 87-87A
Replaced the fuse
Cleaned the contact points on the inertia switch

Any help at all is appreciated.

Your inertia switch is in the DOWN position correct?

Did you check the main relay as well as the fuel pump relay (same relay next to each other under the pass seat?)

If OK, then:

Is the ECU getting power from the ignition switch? With ignition switch turned ON, check for power with multi-meter to ECU plug pin contact #19.

Hi Greg, thanks for the response.

Ok the truck is running

The inertia switch was in the down position and I thought I had checked everything but I decided to check everything again.

I cleaned all the points of the relays, and basically every connection I could find having to do with the fuel and/ or fuses. Ta da! I rechecked the power to the fuel fuse and there was power. I turned the key and on the third crank, she started.

This truck should be completely done in a few weeks.

Good for you, Ben.

If it were me, I'd still be a little nervous not knowing what caused the on/off fuel system.

Buy a couple new relays to take with you when wheeling. They are a common Bosch one available at any import auto parts store for ~$10.

Was everything getting power electrically when ignition was ON except fuel?

Yup, everything else was getting power. I think what did it was cleaning the points on the inertia switch.

I agree with your concern. I'm going to get some hours on the engine locally before I take it anyplace too remote. Good call on the relays too
