My DIYPnP unit just started acting up and I'm not sure where to look. I have fuel, spark, and the injectors are working.... as soon as it starts the Injector PW goes to zero and the car dies in roughly a second. Car is an F2T, modified dizzy, 460 injectors. Please help me figure this out.

Is Tuner Studio showing a good crank/cam/distributor/whatever you're using signal when this happens?

I know nothing of megasquirts, but if this were a stock setup with these conditions I would be looking for cam and crank sensor signals, and expect one of them to be missing.

Probably a MicroSquirt Module inside the PNP case.

Ask your questions and post your MSQ and logs here

If you are using extra code....

So I'm getting a priming pulse from the injectors but that's it... I had it running on starting fluid, and the injector duty cycle and pulse width were both 0. I'm guessing the microsquirt card is probably D.O.A... is that what runs the injectors on a DIYPnP? I got a defective one when I originally bought the kit, but after 5-10k miles it'd be a shame if that were the cuplrit.

I emailed DIYAutoTune so hopefully I'll hear something this week... </3.
