Starting issues
 
1. I'm hoping one of you veterians can help provide some insite. This has been a problem for a long time.

I bought a 1984 with a 6M swap done by the previous owner. The car was running before he tore it apart for the typical headgasket blow out. I proceded to put it back together. Now I can not get it to fire.

* With a new battery putting out 12+volts I have come up with the following list.
* All grounds (body, ECU, Engine, Intake manifold)(yes, this includes the one under the intake that everyone immediately points the finger at.) are strong with very minimal if any noticable drop.
* When the plug wire is pulled and placed next to the block there is a strong spark.
* When the FP test conector is jumped the pump comes on.
* Fuel is gettin getting to the rail - when it is lossened it bleeds profusely with the pump on.
* When I try to start the car the pump comes on.
* All fuses and fusable links check out good.
* Main relays #1 and #2 are triggering and are within ohm spec.
* Open circuit at driver kick panel checks out as well.
* AFM read correct at open and close positions.
* The solenoid resistor reads out ok
* ECU (5M/T) Checks out OK
* When I spray starting fluid the the intake, the engine will run until it burns off.
My thought is that the injectors are not seeing a pulse. What else is involved in the ECU triggering the pulse. Or what else could it be. Any help would be appreciated.

I expect this would have received more attention had it been posted in the MKII section. I'd check the grounds for the injectors, the injector resistor pack (if applicable) and the distributor circuit (the coils... not the plugs, wires, rotor and cap).
