Is there a way to fool the ECU into ignoring the fact that you don't have an auto transmission?Please be sure about this wiring as we are going nuts trying to figure out what is wrong. The injectors are disabled by the ECU...need to know how to trick ECU on transmission issue.Thanks ,Rob

Umm isn't the only diff between the Auto and the Manual the Base timing??? And maybe some boost settings??

I thought there was a TCM for the auto, and you could run the Auto ecu on a manual???

How do you know they're disabled??Why are they disabled??

Check your grounds for the injectors

Get a Noid light a little light and stick it in the injector leads and try to start it.

Check your CAS is working, Spin it with the key on and watch your spark plugs

Make sure you have power going to the injectors.

Other than that I have no idea.Maybe since the Auto doesn't see the TCM it shut the injectors off??????? Guessing.

We have made the engine run by manually sending injector signals. Everything else works.

I'm referring to tricking the ECU to accept that there is not an auto transmission there.

How? What wires must go where? ARggghhh!!
