Looking at buying 86 735i - question - need help

So, previous owner left car on battery charger and key in on position. Car pumps fuel to fuel rail but no spark. They replaced ignition coil, distributor cap, car ran fine before parked and put on charger. Thinking they burned out ECU but interested in what else to check. Thinking cps and other sensor are ok.

Have you tested the sensors on the tranny bellhouse?

Will check both sensors on transmission. I have the ETM and will go through the no start / no spark troubleshooting process I found on bimmerboard's forum.
