Thread: Injector / Wiring problem - Injector 3 Peak Charge Long

just get a 16p rocker cover gasket and injector loom, insulate the spaghetti..... job done.

If you haven`t changed the injector loom in your time when was it last changed ?
I class the loom as a consumable and at 100+k you have stretched the friendship

Thank Gents, I haven't changed the loom in my 5 years and 100k kms of ownership.

Doing research last night I came across a great write up from a few years back where rather than find any potential wiring short, just cut and replace. Going to do that this morning,

D2a Td5 misfiring & cutting out (engine harness)

My wiring looks very similar to that in the photos and still think it has something to do with that. The injector harness was the Jan holiday break project when my Engineer uncle comes out from Blighty, he is car mad and we always find a project to do when he comes out each year.

Think plan is good, do the wiring first, should be a black and white affair, and if it is not that then it has to be the harness and will do that at the weekend.

Thanks again.

Matt.

Don't confuse ECU loom(your pics) and injector loom!
I'd be inclined to just tape the ECU loom (you posted in the pics) back up, and just make it tidy again.
The injector loom is inside the rocker cover.
It runs inside a long plastic conduit with 5 plugs poking out.
Hardest part is pulling the rocker cover off and getting back together without leaking again!

All up about a 1hr job.

Parts needed will be 1 injector loom($100ish) and if yours is old, a rocker cover gasket($25) (Roverlord).

Thanks Arthur, not a good day at the office, still have a car firing on only 4 cylinders. I created a new loom for the 7 wires from the injector harness, labelled every wire both ends, spend $45 on the heat and shrink connectors and built a new loom (see photo), magic moment and the car would not start !

I have been having issues with the connectors, and don't think they bound properly (maybe) - I don't like them.

Anyway, was able to go and get a new injector loom and gasket and replaced that, that all went very smoothly, car started after that, but only again on 4 cylinders.

I got the same error message, but this time for injector 1, so at this point all I can think is that somehow I have got two of the wires mixed up. I was so bloody meticulous as I know the consequences of starting again if I didn't get it right !

So possibly a connector is not tight enough, I have this evening now given up, but I un-taped everything at the connectors and double checked them, removing some and manually joining the wires and taping to see difference that made. Still on 4 cylinders, so I guess I have to start the process again and make sure the wires are all joined to same colours.

Unless there is any other possibility, but as I see it, now the loom is replaced, it has to be an electrical issue and I have somehow screwed up.

Grumpy !

PS what alternatives are there to the heat and shrink connectors ?

I slowly un-ravelled the new loom, and yes, I had crossed the red brown, and red purple wires at the ECU end. Discovered my fault and car started perfectly as soon as I rectified. Then proceeded to build a tidy loom and general wiring tidy up.

Obviously had the loom on its way out, car going more smoothly now than ever has done, so many thanks for the advice to change the loom. Pick-up from low revs better, and smoother, something you do not think is faulty till you change it.

Thanks for the replies.

Matt.
