Yeah, stay inside - T-storms aren't the best thing to be out in whey you're trying to do this work.
>Of what importance would it be?
Just to make sure that the ECU is being fed the right signals.
>I got actually more into: ICM may be wrong...? Even though i have swapped >it it could be still bad connectors?
Possibly. It could also be a bad ground - the ground point for the ECU is at the ground post on the engine lifting lugs. Check for continuity between the ECU connector and the ground point on pins 11 and 25. It should be a
>THan what does ICM has to do with Injectors not getting power more so, I >have spark at disrtibutor and at the Spark Plugs.
My understanding is that the ICM sends a signal to the ECU telling it that it's generating spark and that it's OK to start the fuel pump and maybe also to start opening the injectors.
>I am actually looking for some point to: what is sending signal/ voltage >to injestors? Is it directly ECU?
Right, it's directly from the ECU.
>I see the same colored wires at the injectors, And at the ecu connector >there is only one Red/Blue wire.
Right. The diagram in Bentley indicates that the individual injector wires are joined somewhere in the wiring harness. Bentley also indicates that there's a red/green wire going from pin 14 of the ECU to the injectors. Then, the circuit from the injectors is completed by 2 blue/red wires - one that goes to the fuel pump relay and the other that goes to pin 2 of the AIC.
>Are the injectors/ All of them Firing all at the same time?
Yes.
Another question: Are these Automatic or 5-speed transmissions?
