ok, here it is.
We're in the final stages of a chassis swap, Bought a clean donor minus an engine and trans, chassis wiring harness was slightly cut out, We've been able to cannibalize the old running chassis to complete the harness.
All hard parts (Engine, Trans) were directly transplanted out of a running chassis, so I know injectors are good, (freshly rebuilt and running in old car) also new cap, rotor, plugs and wires from running old car.
As we sit right now, I have a new Wiring Specialties engine and ground harness We think we have every wire, lead and sensor plugged in.
Engine cranks over good and solid, but no spark to dist/plugs, and no pulse at injector harness ( As tested with a NOID light) Again Injectors ohm good at 11.2 ohm's and were freshly rebuilt and running.
Also ECU was transplanted out of the old chassis, A known running car prior to the transplant.
I do hve dash lights and when we crank the engine the oil light does go off, so I know that sensor is working as it's building pressure.
All fuses and relays buzz out good, I'm questioning that the ECU may not be getting power. What supplies power to the ECU, how to I test that?
Fuel pump is good at 40 PSI to fuel rail.
Any help Appreciated.
