I GIVE UP!!!!!!!!!!! follow up to "No Gas To Cylinders"

Update:

I spend all day Friday and Saturday checking wires and I give up. Friday I had a code 43, No STA signal to ECU when engine stopped and engine running over 800 RPM.

I checked the continuity of the wire that goes from the ignition to the Igniter, Coil and Injectors. In its was good. I then checked the continuity of the wires that went for the igniter, coil, and distributor to the ECU. They were also good. I had a rodent problem, so I thought they might had eaten a wire. The only wires that I found bad, were the ones for the sunroof.

I put everything together tried to start the engine and nothing. I have no spark know, but I can smell gas. Not sure if it’s from the injectors or the cold injector. Checked codes again and this time I had a code 12. No Ne, G signal to ECU within several seconds after engine is cranked.

I checked connections, power supply to coil and igniter, and checked signal generator. I also checked the resistance to the coil and I have a question on that. The book said that the primary resistance should be 0.3-0.5 and secondary 7.7 –10.4K. Mine was 1.0 primary and 20.5K secondary. Does it mean that is bad? The book also asked to check IGT signal to the ECU, but I can’t find how in the book.

At first I had no gas from main injectors and now no spark. Could the Igniter had gone bad or is it the ECU? Does the Igniter control spark and fuel delivery?

I just don’t know what else to check and my brain is fried. Any ideas?
Sorry for the long post, but I’m trying to give as much info as I can.


Previous post:

I have in 86' Celica GTS with the 3SGE engine. I just got done installing a JDM engine and it's not starting. At first it was just turning over and not starting. Today I spent sometime looking at it and figured that the cold start injector was not working, the temperature sensor plug was loose. After I fixed that the engine would start, rev up to about 1500 RPM's and die. So, the cold start injector is starting the car, but the injectors are not firing. I got a NOID light tester and checked the injector plugs for power, all of them blinked just fine. I bought an ohmmeter to test the injectors resistance. I tested the first two and they had the proper resistance, so I did not test the last two. I figured it should start with at least two good ones. I had an extra fuel pressure sensor so I also replaced that with no luck.

I don’t know what else to do or check. I keep reading my Chilton book and can’t find the answer. Can someone please help me?

Thanks for you time
