I hope someone can help me! I'm going to work backwards with this issue, so your point may be already referred to further down. Anyway, here starts!
2007 - Vogue TDV8 3.6
The Issue
Persistent fault code, "injector driver circuit performance bank B".
Engine cranks, but does not start.
If cleared, fault comes back up on turning ignition on without trying to crank the engine.
20 liters of fresh fuel.
What I have yet to try
As of writing this I have not done a [sola]noid light test on the ECU outputs / wiring / plug ends.
I have no access to an oscilloscope.
I have not done tests on the cam sensor or any other related sensors, however the fault reoccurs without needing to crank the engine as I've said above.
For "reasons" I am going to replace the low pressure injector leak back/off lines.
Have not done leak back/off tests.
What I HAVE done / tried
Replaced a 3rd party fuel filter with OEM.
Replaced 4 injectors.
Checked and passed: the wiring loom for continuity, resistance, shorting, etc. using multimeter and a megaohm / megga tester, including the sockets at either end.
Replaced the alternator.
Replaced the ECU and had it coded to the car, copied from the old ECU.
Checked common rail for flow.
Cleaned and checked all ground connections to body, then resistance of all ground lines in the ECU box to grounds.
Injector information
Moved injector #1 to cylinder #8.
Installed reconditioned injector in to cylinder #1. (No errors on Bank A.)
Replaced injectors #5 & #6 with 2nd hand injectors.
Injector tests - all 8 injectors
Ohms at 195-200 Kohms as per spec. across pins.
Capacitance at 3 microfarads or greater as per spec.
No short circuits to ground on any remaining/installed.
All read 0.2 megaohms across pins on megga test.
The full back story
April/May - Replaced water pump and thermostat housing, cooling module, power steering lines and fluid. EGR thermostats. Coolant.
Then had to replace thermostat housing again as i'd ripped the gasket on install. Ooops.
Once that sorted, took it for a drive. Drove 200 miles to Hartlepool from Stoke on Trent. No issues.
Drove back next afternoon, 200 miles and no issues.
Few days later, going up a hill - engine limp mode. Switched off. Waited. Restarted fine. No further issues.
Few days later, after a 30 min drive would crank but not start in car park. This time had my iCarsoft with me. Codes were:
- generator field
- injector driver circuit performance
Weird. But I reset the codes, and it started. Lumpy at first, under 500 rpm, then after a bit of revs it cleared and idled as normal. Drove 30 min, no issues.
Few days later, it started but was lumpy as a few days before. But cleared, drove well. But another carpark, would crank but not start. The same error codes, but this time added in injector #8 issue.
After repeated clearing and cranking, it restarted. Again lumpy but clearing. Drove a good 45 min with no issues. But few minutes from home, going up an incline it started limping and then fully in to limp mode.
I got it restarted, but this time it would not move. The lumpy idle would not clear this time. It was trailered home. Then it wouldn't start at all.
A few weeks went by as I tried figuring out what I should do. I had battery on charge in flat. One evening decided to have a look, somehow locked key in car as I connected battery. RAC came while I was in flat, and i got to it and somehow RAC had managed to start the car and it was running well! I was baffled. He said, it had taken some persuading.
So, I took it to the other end of the car park and back but as I pulled in to my space, it started to limp and fail just as I parked.
No more starts since.
Any help and ideas? Many thanks!
