Replaced coil rack. Check engine came back a day later =(

 

Did you read post #8?


Did you do anything about injector #2? Like swapping it with #1 position to see if the problem goes to #1.

 

Post 8 is nothing more than old wives tales and it never works.........

It's not proven at all.

 

 

hmmm bummer, Like I said and others, try to rule out the injector first.. did you try what CCK said in post 17 and what Cruiser said in post 8?

 

Replaced coil rack And injector with lucas injector cleaner. Check engine light came back two days later. I couldn't find bg44k anywhere. Could it be a wiring problem? How do I go about checking that?

 

O'reilly Auto Parts rents (refund) a Noid Light Kit.


See if it works for you.

How can I check the wiring on the fuel injector? Bought brand new coil,new spark plugs,bought the 44k cleaner,tested the injectors with the autozone light-up tester (they were all good)....how do I check the voltage going to the injector #2?? Light is still up for code p0302

 

Anyone?

 

If you checked the injectors with a noid light and they all tested good, why are you interested in voltage going to #2 injector?


Anyway... the Dark Green/Orange tracer wire is the power wire (same for all the injectors). The Tan wire is the driver (ground) wire from the PCM.


Power is tapped off the ASD relay and feeds the injectors through a common splice (S113), which is located inside of the plastic injector wiring manifold on the left side of the engine/next to the valve cover.


The engine has to be running to get the ASD relay contact closed in order to power the fuel injectors.


You could back probe the connector at the Dark Green/Orange tracer wire using a safety pin and check to see if you are getting battery/alternator voltage at the connector. (+) meter probe to the safety pin and the (-) meter probe to the battery negative post. If there is no voltage or voltage lower than battery/alternator there's a wiring problem. If wiggling the wire harness looms along the firewall to the PDC doesn't change anything. Disassembly the wiring manifold and see if the splice is still intact.

 

Yesterday I had P0300, P0353, P0303 and P0304 codes and flashing check engine light about 3 miles from home. Got home, took a peek in the dark(ish) and saw a slight spark coming from behind the fuel rail. Wiring harness was rubbing against it and finally the insulation got nicked causing a short. Shrink wrap, electrical tape and a zip tie to reposition and back good as new. Check your wiring.

 

Nice find!!

 

 

More like <i>lucky</i> find! I cringe thinking what I could have spent on tracing this if I ever found it! The stars aligned that I didn't have a chance to check into it during the daylight hours! Never would have seen that slight spark.
