*EDIT* RPM sensor replaced, problem fixed, thanks for the replies
First post, sorry it a question and not an answer...
I have an intermittent starting problem with my 156 (x reg, 1.8 twin spark, manual, black leather and very nice it is too
The engine turns over but refuses to catch. It happens "every now and then" - about once or twice in ten journeys. Leave the car and it seems to gather its wits again. Happens with a cold engine sometime, others with a warm one.
Imobiliser LED is behaving as expected, and the key-symbol orange light goes out on the dash, as it should. I've swapped over the red relays next to the battery with no success. All fuses seem to be fine.
Last time it happend I disconnected the fuel pipes (only one at a time) where the quick release connections are under the bonnet (just near the wash wipe and coolant fillers) and they were dry as the engine turned over: So, no fuel was being pumped at the point where I would expect the pump to prime.
The car has never stopped running btw, it's only a failure to start.
I've done an ecu reset - although at the time I did it I only disconnected the battery for 45 mins and then reconnected and ran the car for 45 mins. I note in one of the posts here, you chaps talk about position two for 90 secs, off 90 secs, run (which I didn't do, so I'll give that a go anyway, as it's easy.)
I'm guessing it's not a fuel pump problem, they just work or just break, I believe - tell me if I'm wrong there.
Well any thoughts on what to try would be much appreciated,
