Does anyone know what the gap should be on a Crank Position Sensor for Autronic SM4? Ive PM'd Mark Shead, but Im hoping to fit the new sensor tomorrow and get the car running again and am unsure if he will see/read the PM.

I had it running the other day, but was hard to start and was gapped around 0.6mm. We changed the gap to 0.8mm and the car just keeps turning over. I gapped it closer, but proper miss judged it and the lugs hit the sensor, hence Ive got a new sensor to be safe.

Any help please guys, really want the car running so I can bleed the power steering/coolant and see if the exhaust is blowing.

 

Standard sensor? If so standard gap

 

Yep, standard sensor mate

 

Has it run on Autronic before?

If not you have to remove 2 lugs from the bottom pulley (if a std type with 4 lugs), and you have to remove something the phase sensor picks up too I think

 

mine is std gap although mark might have changed it when mapping.. the other is remove a lobe inside the dizzy but as yours is already running autronics it must be done already..

 

i m on sm2 and my crank sensor gap is just the same as it was on the level 6,
i also had to offset my pulley by 30 degrees (i think) not sure if that needs done on the sm4

 

Thanks everyone, Mark has given me the info on another forum Mine has run Autronics for a while, but Ive converted to 2wd and changed the sumps, so the CPS needs to be gapped again

 

Have you got fule in it big boy? lol

 

Miller, I purposefully went and got petrol to be safe as the dash clocks were not fitted and I didn't know if it did or not but thanks for that

 

It's 1mm from memory Fletch.

 

Thanks Ade, car is running now thanks to Mark's suggestion of fouled plugs

 

This is why I love SM4 on the 1.09 firmwear, the data logger lets you see every tooth the sensor does or doesnt see.
Makes you really lazy, bet Mark hates getting the older ones back in for diagnosis now, lol
