I have a 02 classic L200. The engine light came on a few weeks ago, and the engine lacked power anyway. My mechanic plugged it in, and it gave code 46.
He said the turbo wasn’t working properly, so I fitted a new one, that has made a huge difference, however the light is still on, and I have no RPM.
So when I bought the jeep, the rpm gauge wasn’t working, but now this engine light issue, my mechanic seems to think it’s a fuel pump problem.
Would anyone know of any diagnostics we can perform to decide if it Is an ECU issue, or a fuel pump issue.
Any help very much appreciated.
