would appreciate any help with this problem.
Just done a top end overhaul on engine and fitted new clutch, engine refitted but quickly started engine to check all OK (inlet ducting fitted and the cooling system not fitted) . Engine ran fine (just let it tick over for 30 seconds).
But after installing the inlet ducting, air box, rad, pipework etc. The problem arose.
Lift pump not working, so checked inertia switch, fuses, checked earthing cables....all OK. Checked double relay and, as part of the casing was broken, carefully removed/broke open the rest of the casing, 4 diodes are inside. Checked them and found 2 diodes were faulty.
Replaced relay with new but still no power to lift pump.
Now I've noticed that the EML does not come on at all. So assuming the ECU is not powering up, would be perhaps a wiring problem/break ? a fuse I missed ?
Please....Does anyone know the pin outs on the Bosch EDC15 variant 2 ECU, I need the pins for constant power, ignition switch power and earth so I can trace wiring
Central locking etc all working fine, if ignition key left in ignition the warning sound works, so not immobiliser ?
Grateful for any help, Thank you
