Does the crank sensor ever die?
I was driving along tonight when all of a sudden the engine missed a few beats and then died. So I pulled over.
"fuel pump fuel pump relay ECU wiring yeah man torch check it out" were the thoughts going through my head. So I went through the motions. I also pulgged in my backup fuel pump relay. And the car started fine.
About 3 minutes later after overtaking the bus again it happened all over again. Brakes don't work so well with no vacuum servo. All the same I pulled over into a layby.
Same story - it started and off I went.
Well a little later I was driving along and it missed for a fraction of a second.
Later still it stopped and wouldn't restart. So I got the torch out and went around unplugging and replugging the ECU wiring loom. It wouldn't start. So I did the same again.
This time it started.
And it's run fine ever since.
When I was trying to start it I noticed that the rev display was all over the place. So I suspect the crank sensor.
But since I've unplugged and replugged the wiring a few times it seems to be fine.
The question on my mind is: could the crank sensor be on the way out? How much do they cost?
