I doubt that either the ground or the power goes through the ECU. The fuel gauge does, but the pump takes too much current for the ECU to handle. Hence the power relay.

You are probably right about that, I didn’t trace it all the way I just did a visual and spotted that which happened to fix the problem. I was trying to identify the color but it’s all muddy and I was in a bit of a hurry to finish.

mine was just a cheap relay some idiot installed

These idiots that keep doing stuff to our trucks are worse than Cat thieves or hurricanes.

I’m surprised it got hot so fast, it so cool and windy here the ranger won’t even get up to temp for the fans to kick on

Dunno when I slowed down to turn around temp went right back down, getting up to speed temp went way up fast.

That wuhan war whistle probably makes more heat than the entire 160hp of this ford lol.

I accomplished the 285k oil change last night after the fuel pump was solved. Drain magnet looked awesome and had nothing solid just a very small amount of mush. The oil filter looked great too, I saw nothing out of the ordinary, which makes sense because the oil itself looked golden still which just blows my mind for a 5k interval on a ragged old pos.

I put in some 10-40 this time to see if my hot idle OP is over 20psi with thicker stuff.

Cadillac still junk too if it makes you feel better.
Exhaust is on and no more cel, or exhaust leak. But still kinda shakes/shudders with light throttle. Converter slip trying to make the drive smoother, im prob just going to send in the tcm to be unlocked and change tune to either allow no slip or stay unlocked till higher gears. Gm tune is just garbage
