91 200 20v no fuel no spark

Postby inline560 » Sun Apr 19, 2020 1:41 pm

Trying to get this car back on the road, bought it with cylinder head of the car. Been slowly putting it back together. Ran into a few issue's, for one the starter ignition wire is bad somewhere between the relay and starter. Ran a bypass wire and got it to turn over. Tripple checked timing going of flywheel mark. Swapped out dizzy for a known good 7a, swapped over cps, and rpm sensor. Same results

Pin tested hall, cps, rpms, to ecu.
No power on #13 fuse while cranking. Followed smj steps and confirmed power on fuel pump relay.

I'm running a stage 2 s&m autosport ecu that was tested when chips was done.

I dont have the alternator bolted up so 12v for alternator is loose ( dought this could be cause )

Check power and ground on hall sensor plug,

Any input would be appreciated!

Check out if you still have the flywheel pin - They tend to fly off for fun reasons.

If you lost this or have bad g4/g28 sensors your car won't turn on - start there and be make a list of the things you resolve/confirm.
