and look for oil at the ECU plug and clean it out
Done that, cleaned MAF, and IAT sensor as well. Last two cold starts seemed better, but will keep tabs on it.Quote:

After it cuts out, remove key, get out, lock the car, wait a few minutes and try again - not sure if it will help but give it a try.Quote:

Turns over but no fire.
I had a ignition harness I'd been meaning to replace, so replaced it. There was a lick of oil on just one probe at the ECU, so cleaned that.
Still no joy. Checked in here to see what to do next. Fuel purge here we come....
Woo hoo. Working and purring after a drive.
Upon further consideration curiouser and curiouser.
When I did the fuel purge, I thought I should be able to hear the fuel pump whirring, but couldn't. I even stuck my head under the wheel arch and no sound. The engine did start, and the car drove around the block. The absence of sound during the ignition I put down to getting used to the resonance of a Lucas TR6 fuel pump :)
Anyway 30 mins later, I started the car and could hear the fuel pump whirring away when on Ignition 3 and sticking my head under the arch, there's no way I missed that sound earlier.
Intermittent fuel pump? If itstopped working, would there be enough fuel in the engine after a start (car had been idle for 36 hours) to back down a 50 metre drive, stop at the letter box then reverse into the road before running rough then immediately cutting out?
Bet that feels good.
And you think the problem was?
Fuel?
Harness?
cheers
I'm starting to think that they may not have been related? The rough running On start may be independent of the fuel pump cutting out.
I'll know in the morning after she's been standing overnight.

Tack så mycket Anders - mine's a manual, but I'll check all the wires anyway.
Good and bad news today though.
After a cold night, it started first kick and no roughness :)
But she conked out later in town. It's not related to the rough running at start, so I'll start another thread to stop drift.
You should be able to clearly hear the fuel pump if you are standing next to the drivers door and turning the ignition key.Quote:

Another thing to try when the engine cuts out - bang the bottom of the tank with a lump of wood or rubber mallet. You should then hear the pump whirring away and it should start.
