DIY PNP no spark, no fuel, no rpm, CAS?
 

My 95 is sill naturally aspirated but has 640cc injectors, wideband, and DIYPNP. The other day I was just cruising and it died immediately. No sputtering, just dead, and will not restart. All power is working. Will crank over but will not start. It's not getting any spark, and I don't think the injectors are firing. Fuel pump is running and tuner studio is reading fuel pressure. Initially I thought it was the coil, but then I started reading about the CAS. When looking in tuner studio, there is no RPM's showing up when cranking. When testing the plug to the CAS I got Ground, 12.5V, 11.5V, 5V. And the wires on the connector look intact.

Unknown to me, my battery strap had come loose and the ground wire to the sheet metal brace in the trunk was barely holding on. I'm afraid it shorted something inside the ECU box. But all fuses looked good. I'm going to look inside the MS box next for shorts.

I didn't put the DIYPNP together myself. But I am confident in working on the car and the ecu. I bought the car like this and have been daily driving it for about 4 months now.

Thanks in advance

any evidence that it let the pixies out inside the box?
