So I'm restoring and trying to paint my 90 245. I put a newer engine in it after we painted the engine compartment and I am pretty sure I wired everything back up correctly.

Upon first start attempt it ran for 30 seconds with a weird raspy sound but amazingly it ran. I turned off the key and left them two days later it cranks but won't turn over. After going through various no start posts Here is what I know so far:

I have spark at all 4 new sparkplugs

I checked the cam movement under the oil fill cap and it's moving

I have fuel running out the return line after the fuel rail so I assume I have gas getting to the injectors (both fuel pumps are making noise according to stethoscope)

All 4 injectors are clicking according to same stethoscope.

I replaced the ignition power stage with a used one (that I had labeled as good years ago).

So I have fuel, spark, compression, I guess I could bypass the air from the air filter to make surey K&N filter isn't clogging air to the AMM?
When I unplugged the AMM it still didn't turnover so I'm pretty sure it's not that.

If I have spark does that indicate a good CPS?

Any help would be appreciated as I seem to be running out of ideas.

Thanks!
