In 94 IIRC the connector for the sensors to ICM was behind the alternator..

Testing the continutiy from crank wires to ICM would be a good test. Then make darn sure the pins on the ICM connector are all there, and make sure the pins are making contact with the ICM pins. Otherwise..no sparky. No fuel..

Have you tested to find out which you are missing? it'* going to either be spark to the plugs or fuel AFTER the injectors as long as your fuel pressure is high enough to start the car.

Default No Spark

I tested Friday night
Pulled a plug wire and grounded the outside casing of a known good plug to engine and no spark. Tried it in a bunch of good ground locations and no spark
I hope we find the issue without it being a major pain to fix.
I reseated the engine Harness to firewall connector as well just to make sure it was good.
I reseated the ICM connector and the Crank and Cam sensors.
I did not do the continuite test on the harness yet.
That would likely be in the works for tonight

Default Crank and Cam sensor to ICM

The Crank and Cam sensors wire into the same harness as the ICM.
There is a 8 pin (I think) connector right behind the Alternator that connects the ICM/ Crank/CAM harness to the main Engine Harness. I double checked that harness connection as well.

Ok..now..go look at the ICM connector to make sure all the recepticles are all the way forward and can't move. Make sure the rubber gasket isn't getting in the way, and then lightly push each pin on the ICM down to quadruple check they will make contact with the connector when it'* put in place.

Or..you could test for spark and tell us which way we should be diagnosing you.

Unless...you've left something big like the brake booster unhooked and there'* simply too much unmetered air getting in via a vacuum port.

Default Vaccum line schematics

Question
Is there a layout of all the vaccum lines listed anywhere for reference.
I tried the one in Techinfo and the link is dead

Frequently it'* on the radiator support. Although some years it might not be. I believe in 94..it was. (Is that right TFC?)

Meanwhile.. let'* get you to test for spark when cranking. That will tell us which direction to pursue.

Default Finally got it running Here'* the scoop!

When I purchase Engine #3 it came without the Crank Pulley
Brother in Law and I assumed that a 94 bonney pulley was the same as the 95 Riv that the motor came out of
WRONG!!!! We all know what assume means
The crank sensor and pulley are different
The Riv has a smaller tolerance between the grooves for the timing slots on the pulley
The 94 Bonny pulley scrubbed the side of the Riv sensor.
Replaced the sensor with the Bonny sensor and reinstalled the Bonny Crank Pulley
And away she runs!!!!!
So my words to the wise are if you swap the crank pulley make sure you put the right sensor with it!!!!!!!!!!!!!!
One thing we also noted both sensors had the locating pin. They where just different in the clearance allowed.
I now have about 260 km on the motor No leaks No codes and the fluids are are staying where they should be
Thanks everyone for the help!!
I am still going to buy an Actron scanner just so I can look at the live data
Sorry I missed the meet in Brampton!
I was still working on the car Saturday Morning!
