Q: About MS1 fuel pump drivers
Q: Does the MS1 ( PnP ) drive the fuel pump the same way via the same relay as the stock 91-93 ECU ???
I lost my tach the other day while burning an MSQ to the Megasquirt with the lap top. The motor still runs fine with the megasquirt.
As part of the trouble shooting process I installed the stock ECU.
It would start and then die even with the F/P terminal diagnostic terminal jumpered to ground.
I have an igniter on order in case that is the cause that the tach went out.
Regardless, I would still be able to run with the stock ECU as a back up.
Yes, I did unplug the VTPS and installed the fuse normally removed for the MS.
Thanks

If the tach output on the ignitor died, it's a sign the ignitor is on its way out as well.
For some reason the MS is still able to run on these semi-damaged ignitors while to stock ECU can't. Possibly due to a stronger output signal?

no. the ignitor is damaged. nothing else will solve it.
this typically happens when you flash the firmware without unplugging it, but sounds like this burn you did happened to do the same damage.

Actually,I still have to figure out why my motor will not run with the stock ECU. That may or may not be related to the ignitor.
Aso why I fry stuff while just cause I make a change on an MSQ ... So many questions so little brain
I do appreciate the help though.
