hey i have a no spark and its pissing me off. I checked continuity between the B/W from the transistor to the ignition switch and its continuous. And it also has source voltage.
Just to verify where is the Y/W wire goes to pin 5 correct. What voltage reading should i be getting at the transistor?
I have fuel presssure so thats part is okay. Im just concerned now with my spark.
Oh and the green light on the ecu turns on. AFter about 1 sec of cranking it shuts off then turns back on.
Okay so the Y wire on the 8 pin connector that is suppose to go to the ignition switch. What wire is it suppose to go to? The yellow wire on the ignition switch is only powered during cranking (start). But the B/W is a switch voltage source that has voltage in the on and start position. Should i hook up my wire to that? Right now that wire is connected to the Y wire on the ignition switch

The Y wire on the 8 pin is meant to go to the "start" wire on the ignition switch. It's a Y wire from you ignition switch.
The YW wire runs from the 8 pin to the IM/Coil. This wire is important and without it your car will not start.

okay so the wire Y wire is connected for sure at the yellow start wire on the ignition switch and it is continuous between the IG Switch and Pin 9 on the ecu. My wiring from the igniter wire Y/W is continous with pin 5 at the ecu connector. My b/w wire on the coil has source voltage.
I still cant start my car.
Edit:
Does anyone have specifications for the the resitance values on the turbo ignition coil?
Primary: .9
Secondary: 10.73
I dont know the specifications but this is what i got

Primary should be between: 0.63-0.77 Ohms
Secondary should be between: 7.0-8.6K Ohms (so these should be in the thousands of Ohms).
Now those ratings are at 68degrees F. As temp goes up, so does resistance. So I'd say your primary is good. Pretty much anything under an Ohm is acceptable for a primary circuit. But your secondary seems a little high. I still dont think thats enough to cause a non start though

hey my email is darrellbuddy321@yahoo.com
it is a possiblity though right? for the coil to so far out of spec to not start? And also there is hurculiner between the coil mounting bracket and the frame. I scarped it off but i havent been able to check the car yet. IT STARTED POURING RAIN OUT OF NO WHERE! Is the hurculiner a possibiliy also?
And whats with my ecu light? Why does the green light shut off during cranking?

yeah if the resistance is too high then the coil wont be able to fire. If the resitance is too low then it wont be able to develop a strong enough voltage to fire. If your secondary was 10.73Ohms then it wont start. If it were 10.73KOhms then it's a toss up. Temperature makes a difference here but that may or may not be too high. Is it a stock coil? But that reading is definitely out of spec.
I'll send those wiring diagrams.

Yeah the transistor does ground there but the bolt screwing into the fender well should be enough to ground it even if the bracket is insulated. Since you've got ground wires going there just go ahead with removing that herculiner and see if that helps. I haven't gotten to wiring up the engine compartment yet. I've got the rest of the car wired but I still have to put my engine back together. So I'm not too familiar with the wire placement under hood.

so now i am down right pissed off and fustrated!!!!!!! I DONT KNOW WHAT TO DO! I REPLACED MY COIL, CHECKED MY WIRING, AND STILL NO SPARK!
what other compenents can cause a no start? And are there only 3 ground wires coming off of the efi harness?

when i checked with a test light at pin 5 at the ecu during cranking i had no pulse what so ever. The light did not turn on. I checked at at pin 9 from where the start signal is suppose to go into and i am getting a signal.
Can anything else cause pin 5 not to pulse? or is it bad ecu?

Yeah that is DEFINITELY needed. Thats what he's refering to as the ignitor.
When he said resistor I think he was referring to that little cylindrical object That has a wire going in one side and one wire out the other side and it mounts to one of the coil bracket screws. Thats the condensor.
That is unless, of course, he was talking about what you were talking about Heat Rave
