Please post when you can. Thanks
No, you just disconnect the injector. The hardest part is making sure you get on the pins correctly. They are small. It should be .4-.6 ohm at ambient temp. The corresponding pin #'s are printed on the plug. #1-2 and #3-4. At least with this check you can know if it is an electrical failure vs mechanical.do you have to pull them to ohm test them? if so that will have to wait til i rip into it to do the hg's lol. I have had the top end of this motor ripped apart 3 times already and now its going to be a forth lol I dont want to do it again.
Replace them as far as I know, those coils are finicky.Good deal, that said if its electrical is it repairable or would I still have to replace them?
yes the codes would come back quickly, remember, i had two different codes. one for balance/contribution and the other for injector circuit low. I looked at it a little closer, the spool valve moves back and forth, smooth as butter. since one of the coils tested out bad, i will have to replace it. I believe the injector circuit low code was because one of the coils was bad, and the balance/contribution code because the injector was unable to inject fuel. If the screw would not have come out the spool valve may have still worked partially, and i may have only gotten the injector circuit low code until it would have finally stopped. IDK?wow thats nuts, this morning I through a code, P0263 wich means Cylinder 1 Injector Contribution/Balance Fault. If you cleared the code does it come back immediatly ? B/c I cleared mine in the morning at like 0700 and the rest of the day the code never came back.
i explained the ohm test in the beginning, the ohm values for one of the coils was out of spec. There are two coils shown in the picture that move the spool valve back and forth(open and close). My open coil tested out bad, plus the screw fell out, so the coils could not move the spool valve. Save your money on the Rev-X, that is the first thing i did before i educated myself, it did not work. The rev-x is useful if you are having cold start problems, stiction(when the spool valve is sticking).I know this is gonna sound newb but when you say the coils tested out bad, what exactly do you mean ? Is the coil an internal piece of the injector?
...Maybe my injector had slight sticking, i'll throw a bottle of rev-x in thier for extra messure even tho the code didnt come back.
No problem, i'm no expert, lol. But i enjoy helping however i can. I'm hoping this post helps, others with similiar problems. I would test the coils before you pull it out, pulling it out you can inspect for bad orings and blow-by on the copper washer, but that usually causes fuel pressure problems and/or combustion gas to enter your fuel system, with other symtoms included.ok thanx for the info man ! Im tearing my ficm out tomm. and get it sent off to ficmrepair, my volts been low on start. While my truck is down, i'll take the injector out and inspect it along with the wiring harness. If I have any ?'s mind if I hit you up with a pm ?
