Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Bad tdc sensor

The Mtw is stopped after Few miles , after waiting A little Time it is starting and run normaly but it stopped again after some miles . It st arts again and sometimes does the same thing.
We changed duel pump and filter and the problem is always there.
I ll try to change ECU but I think it is perhaps the tdc sensor.
What do you think about this?

Had the same sort of prob,when you have stopped waited and retried starting do you hear the fuel pump? Mine turned out to be a bad live feed on the pump the wire it got warm car stopped. It cooled car started and repeat.
Sorted the contacts and wire no more problems.
Best of luck with yours.

Connect the ECU to a laptop with S&S ProTune 2 and see if there are any fault codes. If the crank position sensor is faulty it will show on that, same with any of the other sensors. Better than changing things randomly.

A while ago I had the same problem. I replaced the fuelpump but the problem persisted. In the end, the grounding of the fuelpump occasionally had problems. I gave the fuelpump a separate ground.

Thanks for yours answers

I have had Crank Position Sensors fail on other cars before and they show the self same symptoms you describe here. One was on a friends' F40 on the way home from his wedding, in the middle of the M25/J6 roundabout, stopped dead, but would restart after 10 mins. And then a few miles later. And again. Might well be the fuel pump in your case, but I'd be very suspicious of that CPS.

I'm waiting the crane sensor and I ll install it with another ground for the fuel pump
