420A No spark, bad vss?

Not finding anything directly on this, but heard it mentioned in a post by a proven member. will a bad vss cause a no spark on a 420a 95???

No. Your speed stops working and there will be no mileage added to the odometer until it's fixed.

I just know that this does apply to the Chrysler and this is a Chrysler motor..technically..

Yea, that's not the case on the N/T DSM's. I use the VSS hole to fill the transmission with fluid and the last time I did it the VSS connector came unplugged. When I jumped in and started the car after the maintenance the speedo wasn't reading when I took it for a drive around the block...

Check the coils... common problem. GL

All that's been done, well really been replaced. Where I'm at now is only 4 volts to the middle prong on the coil connector, I have 12.56 volts to pin 8 and 4 on the ASD but can't get a continuity on the ASD well I can but it's at pins 8 and 4 which shouldn't be happening. And the ECU was replaced about 5 months ago now...new cam sensor new crank sensor..

Testing the coil means checking resistance (ohms) across it.
