Three days ago my 96 PSD (199K mi.) developed a dead miss, I found low solenoid ohm reading (2.7) on cylinder #2 and at this point assume that is my problem. Also, I haven't removed the valve cover yet but will get to it later today, I hope.
While searching for a new solenoid, which have on order, I came across a used set of "like new", of course, injectors from a private party. They are seven, #AB1822803C1 and one #AB182125C2 for $555.00.
He said he bought them for his 99.5 PSD but then found out they were for the earlier model.


This is my first diesel and have only had it for 4 years. I am tempted to purchase them for spare parts but I wanted to here from some of the guys with more experience before I did that.


What do you think?

 

AB's are 120cc split shot injectors that came on the 96-97 Cali model. IF you have a Cali model they are the right ones. If its not a cali, the rest of these trucks have 90cc AA injectors, and those wouldn't work without some custom tuning. It's not a bad price, but you don't know any history? Like new could mean a lot of things..

 

X2 ^^^^^^^

 

Yes, listen to Darin

 

Thanks for the input.
I was really feeling unsure about them myself and I still need to get out there and get the valve cover off. There is a dealer sticker on the back that is from Utah so I want to confirm what's in there now.


The thing that pushed me to consider it was the $520.00 out the door price the local dealer wanted for a rebuilt one. I think I'll keep that money for now.


Thanks again, Mike

 

A 2.7 ohm on an injector I don't think would cause a dead miss. When you get the valve covers off, check all the wiring and connectors real good for burnt pins. May just need to replace the UVCHs and pig tails. OHMing the injectors are just telling you the condition of the coils. Bad wiring could do that too.

 

Passenger valve cover sticker will tell you. A black sticker is 49 states, a blue sticker is cali.

 

Rick, thanks for the sticker color info, it's 1 of 49 for sure. I got the valve cover off and the injectors were #1816187C3 W/no letters, I forgot to check #8.


So far I've,
1. ohmed the UVC harness, it's good.
2. Replaced the harness and ran it with the cover off @ cold idle. There was NO MISS!!!! It was hot when the problem started?


Also there was a very very low oil flow from the #8 injector?? I read on line, that means the injector is not working properly.
I also think at normal operating temp either the solenoid or the #8 injector may be less productive and or fail.


I need to leave again, but hope to return home in time to replace the valve cover and take it out for run.


Thanks for the help, Mike

 

To me that's a little high for cost for a set of AB injectors, unless you know they guy and trust him. I don't trust anything people put in ads anymore, everyone lies to get rid of their junk.

The AB's had inferior parts like the '94 - '97 AO/AA's did so there's a high chance even those will need a LOT of new parts to make them function properly.

Ohming the Solenoids is a great way to tell if the Solenoids are spent or not, but you must ohm them right at the solenoid and not through the harness. To do this properly you must determine the offset of your ohmmeter. For example, when I cross the leads on mine it reads 0.4 ohms, if you have a really good quality ohmmeter it should read 0.0. A good solenoid with my ohmmeter will read between 2.8 and 3.2. If you do the same taking into consideration your offset and get 2.7, I'll bet anything it is a bad solenoid and will give you issues.
Otherwise it could be any number of things.
If you routinely see #8 coming up as an issue, replace your cam sensor and run it again. The new cam sensors almost always show issues with the #8 injector, and the truck may or may not run well because of that.

Good luck.

 

Dzl Jim, Thanks for the advice. I will take the time to measure the solenoid and apply the offset value and have now ruled out the used injectors as everyone here has advised. I do appreciate the advice.

I also like the idea of eliminating some of the easy to do possibilities. I'm going to drain & change the fuel filter and try to locate a cam position sensor locally or order one. I assume Ford or NAPA will be the best local choices.

If I get the valve cover back on and it isn't missing as yesterday, I will drive it to see what, if anything happens at normal operating temp.

Thanks, Mike

 

These guys have you on the right track, for the Cam Sensor, Ford or International are the only choices. Parts store ones (even napa) can be bad out of the Box.

 

By the way, you can get an extremely reputable injector overhaul from the gentleman who replied above (DZL JIM).

All 8 injectors budget overhaul: $500
All 8 injectors overhaul, 160 cc upgrade, new Plunger & Barrel assemblies, new stock Nozzles: $1235.

Thanks for the info on the injector overhaul, sooner or later I'll need to make the choice, new or rebuilt?? Either way more fuel will be good.


I replaced the fuel filter yesterday and was really surprised at the amount of trash in the bowl. I used about a gal. of diesel flushing it out, and the drain tube stopped up several times in the process. I assume I filled up just after the fuel delivery truck left the station. There was a lot of light gray silt, rust particles and other debris. It was really ugly.


I put things back together and it started immediately as usual, and it was running good with no miss. I took it out and ran it up to normal operating temperature, it ran as good as ever. What a relief! Hopefully this isn't an intermittent problem.


I wasn't able to get a good connection on the solenoid pins so I will check it when the new one comes in and I replace it. I also need to pick up a cam sensor and install it and change the oil.


If it continues to run good I have a later model turbo, pedestal, up pipes, and manifolds I would like to install, maybe next year. Retirement is sooo good!!!!


Thanks again for all the help, Mike
