Well, if it comes to that, here are some words from my farmer uncle, who could fix anything. I was helping him fix some knackered piece of machinery, and was worried about getting it wrong:
“It’s f*cked, lad. You can’t f*ck it any worse.”

I guess a sticky relay would be obvious with a multimeter on an unpowered board.
Hi
As soldering has been mentioned here I have a question.
The previous garage had cut the loom to the fuel tank and replaced the 6 pin connecter.
These wires are soldered and 4 of them are wires to the senders that obv work on resistance.
Does it matter that they are soldered or could this effect the resistance readings from the senders?

Looks like it's been reworked to me. They've not even bothered to clean the flux off. I'd be more than cross with myself if I left a reworked board looking like that.

Looks like that LQFP has been hand fitted by someone who's not to bothered about accuracy. At least one row of pins is only 50% on the pads.
A very sloppy job indeed.

I couldn't see any track damage, but a photo isn't the same as seeing it with your own eyes.
Above pin 13 looks worse with a mag glass.
Nice cool day today and the truck runs for 30 mins before faulting. Also resets after a couple if minutes of locking doors.
When the cars hot as it is parked in full sun it faults within a few minutes and won't reset for hours. The only component that gets battered by the sun is the IPK just got a hunch there's a fault with it as it warms up.

A quick continuity test between the pin and test point up the track will prove the integrity of the track. A DMM won't cause any damage as the impedance is too high.

You could be right. I'd be tempted to reflow all the chips myself, particularly that large quad pack in the middle of the PCB. The reworking that's had looks particularly poor to me.
that will be fun, if you have never done one before

True. I used to change those things a dozen times a day, but I forget that there's a first time for everyone.
