Help, No spark on my new build.

I have been having problems with my new build and it seems like everyone I talked to said to join this site and maybe will find some help so here I am.

Main Problem: No Spark (95.5 3RZ)

Misc. Useful Info:
95.5 3RZ Engine
95.5 3RZ Engine harness (which has 2 grey plugs to plug into the ECM)
95.5 3RZ ECM (which is ready for 3 grey plugs to go into it)
97 cab sticker on door says 11/96 (which has a white plug under the dash to plug into ECM)

I have the pin out for both the 95.5 and the 97 and I have made what I thought was all changes needed to the white plug but still NO SPARK.

ANY IDEAS?

 

someone i know that did a 3.4 swap had this issue. he found that he had accidentally miss wired the engine immobilizer circuit. he had it grounded. he just cut the wire and had spark

 

What is the Immobilizer Circuit? Is it in the White Plug inside the Cab?

 

it might be...im not 100% sure. some years have a circuit that will kill ignition without the key... so you cant hotwire it. the older styles dont have the computer chip like new vehicles but still need the key in the ignition

the other possibility is many vehicles have a fusable link between the ignition switch and the coils...

 

You're going to have to break out the multimeter and start tracing signals to find out which one has been lost, so you can find out where it's being lost at.

Start simple. Check for 12v going into your ECU, then 12v out. Manual tranny, check the clutch switch, auto tranny, check the park switch. Then check the input to the ECU with your pin outs. Then ignition switch function, and then check the ignition input to the ECU. Then starter solenoid, starter, etc.

 

Well it is a unique build. So here it goes.
