Donno...well I look at it like this. It might be easier to see if it was running. Not going to hurt anything running on 3 for a bit while you take a gander at the blinky light or lack there of.

Ok, I'll try that. But, you said you've never used the noid, and you used the meter, right? So, if you have, how did you use that method?

Ya, have some one crank it over to test it while idling. I'd start at 20DC, might have to go lower than that to get a good read. You really need an analog meter for this not a digital the digital will not read fast enough.

You can try that with the NOID. I have used meters in the past that's all. I have never used the blinky lights. It might work better, I donno.

I do things different sometimes. I just might be weird...

If the NOID seems to be alright try that wiggle it around a bit. I'm not saying one is better than the other. It's just that I have a meter and not a Noid tester so that's what I'd use first.

Lumpy, Rob, Joe, 92 ............

The noid LIT; Low light and flashing at idle, then sped up to almost staying lit(couldn't tell it was flashing so fast I guess, when going to 2000 to 2500 rpm.

HOLY CRAP, DOES THIS MEAN THEY GAVE ME A FAULTY INJECTOR BACK??????

Either that, which I doubt, or the terminals are not pushing onto the injector good. I would push the terminals out of the front of the plastic connector & put the 2 terminals on the injector individually so you can make sure they are connected good. Then slide the plastic connector back over the terminals. If the noid light flashes then the wiring is good.

Forgot to mention.....

Ohm tested the Injector, with the Multimeter set on 20K(is that right?), and it read-while jumping around- anywhere from 1.5-3.7ohms....The book says 3.0, but could that be negligible? Which, if it's proven that my injector is working properly, .....WHAT, EXACTLY?

^^2X on this one...

Sounds like out getting power to the injector and you had the injector rebuilt. So it's very possible the plug and the injector are not playing nice.

Ok, Rob, so the wire is hot, CHECK.

But, why, then, would #2 pipe be cold, other than no fuel to that injector or could this be more valves? I read someone say that good compression on that cyl. doesn't mean that the valves are set right. Supposedly, they triple checked that, and set them to the RV Cam, told me I was good to go. Now, when I initially had the firing order wrong, could that have damaged the camshaft or valves?

BTW, this connector has a boot over it, ...how do I get to the back of the wire crimps inside, to push them out, with that boot on there?

Should I try to mickey mouse some connections with wire connectors and prongs on either end, then connect it and see if it runs right, before connecting the connector again?

Having the firing order wrong "should" not have done anything to the valves or the cam. You really gotta have a bunch of stuff go wrong to get that type of damage.

If you have spark to that plug and it's still missing then it's a fuel issue. You said that you checked for spark and also changed plugs right? Maybe swap wires between 2 & 3 and see if you have the same issue.

I'm not sure, I'd have to take a look to see what mine look like. I's been a bit since I have paid that much attention to the injectors.

You can do that just be very careful that the wires don't come off and short out somewhere. If you are able to modify butt connectors they might fit tightly on the injector and the wires on the other end go into the plug. Might be worth a try.

Doesn't sound like a bad idea.

K, crimping now. But, if I get good power to it, and it's still running on 3....I'm really lost, man!

I also didn't think that, maybe, in the process of man-handling the wire connector, I regained connection?

This is really frustrating, being so close and it's still sitting here in the driveway!

Hmmmm Interesting. Like I said I don't recall what mine looked like, still covered with mud.

Are you sure it's an injector plug you're messing with??? Not being mean but I've seen stranger things happen.
