No injector pulse to any of bank 2 injectors 2006. Mustang gt
I have a 2006 mustang gt I can’t get any of the injectors to spray I have sent ecm in to be repaired they said nothing wrong with it I have checked each wire back to ecm and checked all ecm grounds bought car with blown engine rebuilt it and have invested lot of time and money into it need help badly please any ideas
With engine running I can unplug the injectors on side not spraying and volts on signal wire will show .04 or .05 volt the side that is working will show .07 volt on the signal wire
Does the power feed light a test light? If your using a multimeter and front probing the connector could have 12 volts but drop out when loaded. Cam sensors hooked up on the bank not firing?
Yes I tried a mood light will not flash it and I checked the timing it is in time I belive i called myself checking it twice but will look again someone mentioned the little diodes that bolt to front of the heads I wouldn’t think they would hav anything to do with it tho and my altinator isn’t charging right now but hav had jumper cables hooked to another vehicle running and no difference
I have not replaced the crank sensor yet but if it’s telling the one side to spray I figured it was working I been thinking ground problem from beginning but have checked and cleaned every one I can find on it
Any trouble codes?
There are some faults that will result in the intentional shut down injector drivers. Cylinder head over temp and catalyst damaging misfire codes will shut down injectors for sure.
I’m going to go back and try pulling codes again today before it had only set the misfire codes for those four cylinders and I will try to hook a scope up to it I told the what issue I was having with it tho surely they made sure to check the injector drivers idk I will also double check timing on that side again thanks
I double checked it does light a test light while running and I checked all the grounds again codes it set are P0205 thru P0208 injector circuit open have you ever heard of G7 ecm repairs in New York that’s who I sent it to and a friend who owns a shop near me used them to repair a ecm for late model Chevy durimax he recieved exact same letter I did back with the ecm said no hardware problems could be found but the software was corrupted and he has tried everything on it and still not running I think they saw me coming apparently still havnt put scope on it yet but will tomorrow
Yes I have checked all power and grounds at ecm and it is a 4.6 3valve I have checked the relucter ring on camshaft I will look at it again tho i could have overlooked something
Still havnt fixed it yet the altinator was not putting out enough voltage so replaced it the battery light still on it doesn’t charge unless I unplug the three wire plug in on altinator
I can get number 8 to hit every now n then and number 5 and 6 were hitting every now n then when I wiggle the harness so I’m thinking something is shorting to ground causing it to shut those injectors down or something ? Idk I don’t have a scope but may have to buy one
