VR Sensor Gap

Postby Dan Lee » Fri Jan 12, 2018 9:23 am

I have a Ford 400 motor converted to EFI & EDIS. I use a 36-1 Reluctance wheel and a Crank Sensor of a Ford Taurus. This is not new, I have run this setup for a while, but I had a VR Sensor go bad. I replaced it and it ran for a minute. Now it won't start. I am getting intermittent spark. It appears like the sensor is not working properly.

I have ~0.020 gap between the sensor & the Trigger Wheel.

What it the spec for the gap?

.020" is probably close enough for most, and "it ran for a minute" seems to confirm this. How do you know the old sensor failed? Have you checked the new one to see if it failed in the same manner? You might be better-served to post this in another forum here, like the "General Support" and give details of the MS system you have and the MSQ/MSL files.

The trigger wheel ran into the old sensor, and destroyed it. Something came loose to cause that. I remade the bracket since, and the sensor is solid mounted. I think the previous bracket had the sensor much closer. I use an EEC-IV and EDIS-8 module. It is full sequential injection with a mass air meter.

There is no factory bracket to mount the sensor. It has to be custom, but it would be nice to have a spec for the gap. I'll have to try to get the sensor closer to the wheel.

How about posting a tooth-log?
