I have my motor at the dyno after a refresh and it will not fire. He says it has spark, fuel pressure and can hear the relays clicking but can't get the injectors to fire....Any suggestions? Sorry I don't have more info, just got off the phone with him and that is all I know at the moment. Any help is greatly appreciated! Thanks in advace!

Use a Noid light to determine if the injectors are being told to fire. If they aren't then you need to determine if something is wrong with the harness , the injector driver in the ecm, or the pickup in the distributor. You can have spark and still not have a signal to fire the injectors.

Make sure you havent pluged the IAC motor lead into the distributor and the distributor 4 pin lead into the IAC. The 4 pin connector on the IAC and the Distributor are the same. Saw one last week. If they are reverse you are not getting a signal to the ECU to fire the injectors. Oh, one other thing throw away your IAC motor and replace it because it just got driven to the end and held with current and is burnt up.


IAC wires are green in color
DIST - wires are red and pink
