89 740 Turbo LH 2.2 No spark, dead in the water, replaced alot already 700 1989

I got a 89 740 turbo with lh 2.2. It died going down a city street at 30mph. It was hard starting ever since I got it 3-4 months ago. Sometimes you would have to put the pedal down to get it to catch and fire.

After that 30mph city trip it came home on a flatbed and wouldn't start. The tach doesn't move at all.

It has new NGK spark plugs, gapped at .028 standard ngk, non iridium.

New FPR vacuum line, a few new vacuum lines here and there.

New water pump.

hitch, trailer light wiring done with relays.

Battery died and I bought a new one for it, I ended up swapping a 3-4yr old battery from my 940T, but it has good charge. Charged it up after trying to start it aswell.

Fast forward to after it dies:

New power stage

new ignition coil

records say wires are about 40-50k miles old. Looked good

New hall sensor (because the tach was not reading).

Hall sensor was drilled out carefully then jb weld'd in place carefully using 2 people and a vice...

Put in a working Fuel pump relay from my 940T.

Swapped the black relay by resistor pack and power stage, its good.

Fuel pump doesn't turn on when turning the key to II anymore. Theres' no spark at the coil. The gas guage go's up, it's got half a tank in it.

I'm not sure what it is at this point other than maybe the ecu is just dead.
