In need of some help guys, a mate of mine has a Vrs that recently had alternator failure and resulted in his car cutting out on a main road about 3 weeks ago due to the battery being completely drained. I put a battery on it at the side of the road to get him home - car drove fine, got it home and parked it up, then after replacing the alternator it started up but was really lumpy and eventually conked out.... no it will not fire at all. He's had a look at it, can't see any plugs off sensors, or wires off the alternator etc. He's checked fuel coming to the rail, and the spark plugs are firing. I've scanned the fault memory and no codes are coming up. It had a compression test done and cylinders 1 and 2 were reading around 5-6 bar, and cylinders 3 and 4 read 7-8 bar. The engine is turning over at a good speed, sounds like it wants to go but it just doesn't fire.... I suggested a crank position sensor may be at fault, he's fitted 1 off his old engine but it made no difference.... we're trying a brand new CPS this week but I was wondering if anyone had some ideas as to the possible cause? Another friend of mine had a similar problem and it ended up being an ecu fault.

 

The car is a ko4 converted AUQ lump btw!

 

Any help would be greatly appreciated 

Sounds like ECU at fault and with all this crappy weather water could have gotten in somewhere and fried something. I'd get it double checked by a specialist though

Thats what I thought tbh.... going to get my hands on Vagcom and have a butchers
