I picked up an engine harness on eBay and was planning to install it to resolve the issue but I can't seem to get access to all the connections even after dropping the engine the prescribed 4cm as described in the injector change procedure.

The wires are spliced in a few inches from the #5 then run across the top of the engine and directly to the #3.

The engine seems to run ok, it's a bit rough when cold and at idle.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Is a wiring harness change possible with the engine still installed? I have a 2001 Carrera cab. it's throwing a P1229 which is a short to ground on the #3 injector circuit. The engine seems to run ok, it's a bit rough when cold and at idle. The previous owner has hacked the wiring harness; as far as I can tell the #3 injector wires now come directly from the #5 injector. The wires are spliced in a few inches from the #5 then run across the top of the engine and directly to the #3. There is no sign of the original wires from the harness near the #3 injector. How does that even work? The wiring diagram shows that the injectors share a common ground but the other wire connects to a separate valve for each injector! I picked up an engine harness on eBay and was planning to install it to resolve the issue but I can't seem to get access to all the connections even after dropping the engine the prescribed 4cm as described in the injector change procedure. Hopefully access may be possible by removing some of the engine accessories I just don't want to start pulling stuff off willy nilly if there is no chance. Any help or suggestions would be greatly appreciated.

So it's unanimous then...I have to remove the engine but its dead easy huh:-)
