wow. all i can say is I am lost now lol. I had no idea that there was a correlation to the opti not working properly and the injectors not firing. thats just wierd in my opinion. shoebox should probably chime in on that and tell us if that is normal or not

Im stumped.
If I have no spark anywhere ( only sign is the noid light has a faint flash during cranking ) and fuel at the schrader valve, but none at the injector during cranking, mind you there is slight mist.

What would make it have these symptoms?
We thought it was the B14 ( dist ign feed ) but we rewired that, unless it is in the connector pin at the PCM.
I have done numerous search threads and people with similar problems have ended up fixing it with new opti.

Since mine done have a sign of life, it seems it is getting the signal, just a very weak one.
Someone give me some tests to do to narrow something down.
Thanks in advance
