Diesel engine not starting

MevagisseyMedic · 19th September 2014, 15:43

I have someone who has a 03 Diesel ZT which will not fire up.

bought it and not ran since getting it.

He has checked in tank fuel pump - fuel coming up to engine
Replaced under bonnet pump
fuel present at fuel rail
New fuel filter
Injectors cleaned
Glow plugs Glowing
PCV filter ok

Called RAC out and left this report

Any advice please.

Hi,consider two ways:

-Electric issues (ECU flooded for example)
-Fuel (lack of pressure),low side and high side)

Have a look here:

Ecu is fried probably due to water ingress.

Hi Phil

Plenun drain clear and dry, but doesnt mean it has never got wet.

Can you test it if sent to you?

In case of ECU flooded,neither LP pump runs

No that's not correct Mike, moisture runs up the outside of the pcb and shorts the IBGT fets (ignition drivers) the ecu also has a fried can-bus controller ic.

Yes Mark, I can take a look at it for you.

Not always Mike, looking at the fault report, more than likely an injector drive fault

Manual or auto?
