thanks. Yeah I've gone through everything with contact cleaner, dielectric grease. Have noticed on my big red/wh constant still corrosion on crimp side engine bay 8mm fatty terminal connection. So last night prepped donor harness which despite having mud in the loom, actually after i sprayed down and brushed was in pristien condotion. Ready to go full harness swap( but for the 2 terminals I've already poached, coil signal and 2 wire thermo termies

 

it ran for 2 day when I swapped the computer. Then left me stranded. Since I've cut holes in both beds to confirm my pump install was right(stuck on e) and my adjustment was minimal but all arrows line up. Fuel rail popped air, no fuel. Thinking may have ran out of gas? Found 2nd jumped wire @ the pump wh/bulk and tracing it In the morning

 

51 Oxygen sensor stuck at lean position
42 Fuel pump relay control circuit (not asd)
I'd sort these out then go to the 27 code.

 

Merged two threads.

Lets just use one, ok. Having multiple threads on the same problem just leads to confusion on what has been done, and what other issues may have come up.
