Looking for a fuse diagram for my LP

[rich12]

Hi,

I haven't got the owners manual for my car and am struggling to find the actual diagrams online.
I just need to know where all the fuses are and what they do just to make sure the ones in my car are correct/not blown.

The car just refuses to start and i'm running out of ideas.
Any help would be massively appreciated.

Could be crank speed sensor...

What makes you say that?

Common fault in modern cars. Starter turns engine but unless ECU sees crankshaft rotation and establishes TDCs etc it wont know where to fire spark and fuel.

You didnt give any clues, so I assume engine turns via starter. If engine not turning then starter, wiring to starter or immobiliser....

Thank you. It doesn't crank at all.
I can manually crank it.

I've changed the starter motor, the battery and checked as many ground cables as I can find and also cant see any loose/damaged wires.

The ignition comes on and all the electrics work but when I turn the key to start, it doesn't crank.
I can hear the fuel pump and the starter relay clicking.

The fault code on my little code reader is;
Park/Neutral switch input circuit, short to ground
No communication with engine control module (SAE ECM/PCM)

Doesn't that indicate that the switch to detect the gearbox is in park or neutral is faulty (so the ECU thinks it is in gear) which means it won't turn over?

I honestly don't know.

With the ignition on, sometimes I can cycle through N, R, 1, 2, 3.

I don't even see how you can get the sensor out without taking the whole thing apart.
