My 3.0 v6 has spark but no injector singal. Replaced ecm rebilt! I have 12 volts going into crankshaft / cam sensor. I have ground singal on cam side but not on crankshaft side. Will this cause me to not have injector singal? THANKS TO ANY AND ALL HELP

 

I have a mitsu service manual for my Talon, it is the best return on the money I have spent on the car so far. Try your local library for a repair manual that may help you test some of the circuitry. BTW, how do you know you know you don't have an injector drive signal????? If you did not have spark I may suspect the crank/cam position sensor but....are you sure you have fuel pressure and the pump turns on?

 

I hooked a noid light to injector conection and no singal. Yes I have fuel pressure 52 psi unregulated. THANK TO ANY AND ALL HELP!

 

I am not sure, but your noid light may not light up as the activation time for injectors is in milliseconds (.001 of a second) and when cranking may be as high as 30 or 40 milliseconds. As it takes time to heat the filament up, it may not "react" and light up. Most auto shops hook the injectors up to an oscilloscope to view the duration time so I am not sure a noid light will tell you that they are firing.

You may try an LED as solid state devices do not have any "lag" time. Check the web for information on LED's.

Check your ground connections to the ECM and recheck the connector to make sure it is fully inserted.

Check the fuel injector relay, I believe all mitsu cars have them.

You do have a mitsu manual to troubleshoot, don't you?

A lot of these crank sensors are Hall effect sensors, and I have not really investigated to find out how to check this type of sensor. It may well be your crank/cam sensor, but I realize that the cost of just throwing a new one on is not cheap if it does not fix your problem and the store will not take a return on electrical components. So how to check this sensor, I do not know....yet.

 

TUSR, any update?
