L4760 p0202 p0201

[Twesley]

I have a l4760 that I purchased not runnin. I managed to take care of some things and got it fired up and have a P0202 and a P0201.Inspected the wiring closely and did a pin test to the ecm, and everything seemed to check out. Also swapped out the 2 injectors with one from my l3560. Did not help.

Are you just getting codes or is only running on 2 cylinders?

 

[Twesley]

Definitely not running on all 4

You can not swap out injectors without programming them.
I hope for your L3560's sake that you put the injectors back in the same position as they came out of, otherwise you will have future fuel issues with the L3560.

Swapped out and the 3560 runs fine. Try again

When you checked the wiring back to the computer, did you also check for any shorts to ground?

Other than a frayed wire, I think you'd be looking at a bad injector driver in the computer.

40 fan I am afraid u may be correct. I will look at the harness much closer but I will be pleasantly surprised if I find a spot. Thanks

If the injectors were not reinstalled in their original position, in time you will eventually damage the engine by either overfueling or underfueling condition you just created.
