Put a 89 camaro tpi mtr in my blazer. Keep in mind most of wiring is custom. Starter is wired through button, have vats bypass on it. Have spark, but cant get injectors to pulse. Put noid on injectors can get them to fire if i put 12 volts to dist ref. wire b5 ppl/wht. Changed ignition controll module in dist. I'm stumped bought ready to put a bullet in it.

 

well you didn't give us much information. tell us how you wired everything in? you just said if you put voltage to the distributor reference you get the injectors to fire, so, you hooked up the ignition wrong?

 

Factory harness less the egr, purge can, port air.. My fuel relay and ignition relay wired of toggle on dash. Put 12 v signal from fuel relay to ecm for fuel signal. Checked all my injectors all 16.1-16.2 ohms. Voltage at all ecm terminal pins where should be. Check my ecm only code is a 12. I'm running msd 6 offroad ignition and msd blaster coil. Never had the stock coil. Notice in schmatics stock coil has some additional wires to it. Do i need to jump pick signal to the dist reference?
