Right chaps. I am getting very weary of all this. Possibly not long till my former pride and joy is torched and I claim my rather tasty agreed value from my insurers.

Last night, after fighting all afternoon fitting my new alternator, which is a twat of a job on a turbo, and realising it's probably the air con compressor that is noisy, I drove off to play footie with my mates as I do every Thursday night. On way home, biblical storm, but defo not drove through any large puddles, car chucks it. Pulled over, restarted no bother. Drove half a mile, chug chug, half a mile of chugging then cuts out. Starts on key but immediately dies. At this point it is 11pm, I have only a wet t shirt and shorts on, and I'm stuck in the middle of a roundabout. Long story short AA got the car home for me by 3am! Freezing doesn't even start to sum it up!

So after same fannying about today the car starts and runs with the fuel pump fuse out, clearly only till fuel in rail runs out. Which incidentally is about 10 mins. As soon as fuse 34 goes back in it chucks it instantly. I have changed the DME relay, the FPR and the fuel damper. Pump is working fine it would seem. Half filled a litre bottle in seconds when I cracked open the fuel rail and cranked it.

Last night there was water round about the base of my fuse box. Can't help thinking something is shorting as soon as the fuel pump fuse is connected although no fuses have blown.

What else does fuse 34 do? It says fuel pump, which it clearly does, and fuel sender. My fuel gauge still works with this fuse out.

Edit to add took fuse box out to check and seems bone dry.

Help. Or else give me matches.

I now hate my car.

Ok chaps I found the problem. Broken wire on the loom of the SciVision, so understandable that nobody shouted up a solution! Fixed wire and it started right away. Is running a bit rich, a bit less rich after a quick blast, hopefully settle down tomorrow but I can live with that and get to the bottom of it. I wonder if I got any petrol into the oil with all my fruitless cranking? Is that possible?

Cheers

Quite possible, I had a problem with the injection system on my 924 when it was sorned for 14 years.... would only run on the fuel in the rails, with no pump running..., and flood if pump was working... got it sorted, (sticky valve in fuel metering head) but had at least 2 Ltrs of petrol in the sump acording to my indie who sorted the problem!.
