transit non start.

afternoon all, had a call last night for a 65 plate transit 2.2 euro5 non start. apparently been driving fine parked it at a job came to go home and it wouldn't start. I told him try some easy start and id get to him today. he messaged this morning saying it will run on easy then dies when taken away , so I said get me a fuel filter just incase. turned up this afternoon plugged it in only codes were for all 4 glow plugs and clutch switch. after checking clutch on live data I deleted the code so no issues there, plus it would crank anyway. now then, fuel pressure key on was sky high like 1600bar 😂 so I thought fuel pressure sensor.

I had 5v ref, signal but ground had 6.7v disconnected and 3.4v connected. I probed the ground and earthed it through my test light, straight away on live data fuel pressure came down to less then 50bar, cranked it and it started 🎉. this is where it could get interesting, I traced the loom to the ecu, 1st connector on left which had a cable tie holding it in 🤦‍♂️, plus the coolant tank above was empty and looked like it had been leaking on to the ecu. I disconnected the plug, it looked wet inside and 1 pin had some green crusty onit. I did a continuity test on earth wire from fps to ecu plug and she beeped fine. so question is, is the ecu fecked by being shorted inside or something else 🤔
