No Injector Pulse!???

[mitten_e30]

I was driving my e30 m52 swap and slammed on the brakes and the car suddenly shut off. I was low on fuel so I put more in the tank still no start. I jumped the fuel relay and it fired up then died. I put the relay back in and got it running and drove it home no issues. Let it sit for an hour and it wouldn't start. I assumed the pump was going bad so i put a new one in it and still no start. I have no injector signal but there is 12v to each injector. I have spark and compression and it will run on starting fluid. I tried jumping the fuel pump again and now it won't turn the pump on and i only have .4VDC at the main and fuel pump relay. Fusible link is good. The battery ground appeared to come loose when I slammed on the brakes could that have fried anything? Any help is appreciated I'm almost ready to sell this car.

Check ground wire at front of.motor, I hit a hole in road and mine broke, there super.brittle

Check cam position sensor.

bad cam sensor just batch fires injectors, will still run fine for the most part. I would look at harness power/ground, engine ground and crank sensor.

If it's not ground related, I would try getting your hands on another DME.
