From what i read on line you need a DBR-II to test voltage on the injector wire. My chilton manual didn't have any detailed info on that code.

"Turn ignition off. Disconnect injector No. 1 connector. Turn ignition on. Using DRB-II, actuate fuel system. Place DRB-II in voltmeter mode. Probe Dark Green/Orange wire in injector connector. If voltage is less than 10 volts, repair open Dark Green/Orange wire. If voltage is 10 volts or more, replace engine controller."

 

You may have a bad injector driver which is in the ecm. I don't remember if you can disconnect one injector at a time and try running at a higher rpm to see if that narrows it down. Also make sure you are getting vacuum to the map sensor (on the side of the throttle body). Hope this helps

 

Good advice, thank you. I can't afford the scanner so maybe i can find a mechanic to help.

 

Thanks! I'll try the disconnect and higher RPM. I'll also check the MAP. I cleaned and dielectric greased the ECM, and it seems to be running better. Still a lot of smoke. I'd like to get the voltage tested, as Moparite suggested.
