Just changed the gearbox in an 8v Digifant, everything back together, just the clutch cable to adjust...
Turn the key and the fuel pump is running continously (not just priming) and the car won't start. All earths are in place on the engine and checked with a multimeter.
Think I've blown the ECU, had it apart but can't see any obvious damage, anyone fixed one or am I best just getting another? Any suggestions welcome...
-
I believe it is common to miss the gearbox earth strap and that in turn blows the ecu
-
Yeah I know about that one, gearbox earth strap is and was on, however, I believe that the symptoms I have are exactly what you get with a blown ECU.

Yes sounds like it has blown. :smiley:
-
Damn Damn Damn :grin:
Need to try and get one tomorrow now....
-
Does anyone know which ECU I am gonna need to get?
Are they all the same as long as its Digifant II or do I need to match the part numbers?
-
Match the part numbers as there are a stack of different models, it's not just the Numbers but the suffix letters - I have a couple in stock if they are of any interest...
-
It says on it
Bosch
0 261 200 298
Digifant II
DF1
037 906 022 DB
Do you have one and how much?
-
I dont have a DB version only a BC & N
What year & engine model is yours?
-
Its a 1991 mk2 8v
-
Having said that the 037-906-022 N model I have matches the Bosch Part Number, but not the VW one.... :huh:

So what we need to know is how interchangable they are, anyone?
-
Managed to borrow an ECU, same as the one photographed above from someone locally (I have to replace it)
Fuel pump primes and then stops which is now right but the idle control valve is running constantly, is that normal?
Car still won't start, got the plugs out at the moment as its damp in there...
Don't seem to have a very good spark, anyone got any suggestions?
-
you've f**ked the sparky plugs ?? or they need a clean from being dowsed in petrol ??
-
Yeah you probably right, will put a blow torch on them and see if that improves things once I have let everything dry out a bit...
-
Pretty sure the isv can stick sometimes, take it apart and cleaning it out may make it go off when it's suppose to.
-
Finally got the car started, took all the plugs out and put an airline down the holes, heated the plugs up - still no joy :angry:
Wasn't getting a spark so started checking other stuff, turns out that the ignition module on the ecu bracket on the ecu I borrowed was no good, put the original one back on and it started straight away.
Just need to do an oil and filter change as the oil smells a bit of petrol after the original ecu failed and completely flooded the engine.

I had this happen on a breakdown I attended once, pulled out a plug and the injector had stuck open, lots of fuel, hot engine bay, flames, oh f**k. Thank you Mr fire extinguisher!!!!!
