Title: 16v cut out and won't start.
Post by: nightroamer on 01 May 2011, 16:26

Guys

My 16v cut out this morning and won't restart.
I have checked the spark plugs and there was no spark so I changed the coil and dizzy cap, rotor is fine.
When I switch on the ignition I get a single spark as you would expect but there is no spark when cranking.
Also although I can hear the fuel pump running the cylinder i checked did not smell of fuel and the plugs were dry.

Does this sound like a sensor fault?? ATM my car is stuck a mile or two from my gf's house  :cry:

Anything common can check?

Many thanks

I think it's actualy a single output module. Not 100% though. Either way I have a new OEM unit fitted £52 ouch...

my 16v was cutting out recently and I checked all the wires and discovered that my crankshaft position harness was severly deteriorated i have a new one on the way I hope it fixes all the problems I've been having.

the crankshaft position sensor is located behind the front motor mount near the starter, the wiring harness is really long it goes toward the front of the engine, around the oil filter adapter plate, and up to the harness plate with all of the plugs on the front of the motor between the motor and trans its the black plug closest to the radiator on the bottom of the plate, if you have an ohm meter you can unplug it and test the wires for a short there, mine all had 0.4 ohms resistance between the 3 wires= obvious short... good luck, hope you find the problem..

Cheers thanks for the reply.

I will test for shorts, does anyone know how to test the hall sensor?
It has a power supply, but how can I test the sensor wire?

Just had a mate look with vcds and no faults shown after clearing the ones I had created testing.

Bummer....
