Default Solved my fuel pump electrical issue

I tagged on to a 4 or 5 year old thread a few weeks ago thinking I was having the same issue. No fuel. It was looking like a bad gray wire or something along those lines. I back burnered it because we've been working on building a shed in the back yard and I can drive my Tacoma instead.

Anyway, after mowing today got back after it trying to figure out what in hell was going on. Looked up a schematic on the relay, energized the pump in the fuse block and low and behold: it started!

Checked and was not getting the 'go' signal to the relay. Also checked the ground. 43k Ωto ground Pulled the fuse panel apart and checked again. Same. All the other green wires were 0 Ωto ground. Soldered a fresh ground to that green wire and ran it straight to the battery (what? 6 or 8 inches?) and was 100% confident that it would start. It did!

No idea why the ground broke, not too worried about it but will scope out under the car when I have it up in the air next time to see what in hell is going on with the clunks I"m hearing on every single bump in the road

Until then, I'll get 'er out and run 'er a bit to see. Still ahead on AAA...2 tows in the 3 years I've had it. $45 for the first one and $75 for the second. Cheaper than the $100+/year for AAA

Congrats!
Its refreshing to see some actual diagnosis going on here, contrary to the typical internet story.
It's sad how much time and money are wasted without it, just swapping parts in hoping to get lucky.

I repinned the grey fuel pump wire and replaced the grey block. The wire got hot and melted the clip. I also cleaned the Neg wire in the back, and hooked up the Racetronix fuel pump harness. I had been having issues for awhile with my car not starting and fuel pump fuse blowing. Its been a week and no starting issues..

My grey block had some slight browning/discoloration from heat but very slight. Good call on the ground at the back. I'll make sure I add that to my list of **** to do next time I get it up in the air
