Default All sorts of fuel problems.....

First I replaced my fuel pump which wasn't the issue to begin with so i actually got out the DVOM and traced it to the Multi-Function Relay, so I replaced it. Worked perfectly, ran great, End of problems... so it seemed. I just spent a half hour trying to solve my no fuel issue in a parking lot.

Power at fuse and power at MFR, but no power on FP or at connector in rear wheel-well. After finding this out i checked inertia switch, no power on either side am i missing something?????

That said, I unhooked my meter and walked around the truck ready to give up for the night and I heard hiss of my FP priming up. I made a very loud sigh of relief said a few dozen choice words got in and drove home.

It may be that im just tired and frustrated but, if someone could point something out to me that i missed that would be awesome!!!

Hard to say. The FP is only supposed to run for a few seconds when the key is turned to Position II. This makes it difficult to turn the key and run to the front or back in time to troubleshoot or poke around with a test light.
Having a helper to turn the key helps a lot.

That's what I thought Fish, but ya know what is really odd though, mine has always run constant when I have the key on for some reason. Why would that be???

And this is going on 2.5 years btw

Ecu problem?

No sketchy wiring that i could find, but it wouldn't start again this morning so i get another chance to trace it i guess.

So weird things happening... traced it out to the problem to the MFR... kinda. If I try to start it just cranks and cranks. Just for the heck of it I had my girlfriend push the hood switch down and I started her right up. I was unaware that the switch had anything to do with the fuel pump since I've started it dozens of times with the hood open. I just find this odd

Never mind scratch that, still looking its like there is a delay on it now. I turn the key and have to wait anywhere from 20 seconds to 20 minutes for the relay to trip and the pump to start

Have you checked/replaced the fuel pump relay ( AFU2913L ) in the RH footwell (RAVE K119)?
