Not sure if it would cause the no start, but may cause a problem elsewhere.....

When you replaced the FSD, did you dig the resistor out of the old one, and put it into the new one?
 
Hmm . I thought they could run without it but I am not sure. That could be it. Well let's put it this way, you need it so do it. a #9 works nice.
 
You will need to put that resistor in line. The resistor is usually stuck in place on the pins inside the plug on the FSD when you remove the harness. You need to carefully pull that resistor out of the old FSD. This will be next to impossible, if the old FSD is still attached to the side of the injection pump.
I'm no authority on the subject, but without that resistor in line, on the new FSD, your PCM, is likely reading different electronic values than it is used to seeing. That MAY be the cause for some of your starting issues, but there are other postersm ore knowledgeable than I, that can clarify that for you better.
On that resistor is a number, IIRC, they are available in values from a #1 thru #11. The one in my truck is #3. Through research from the good folks that have gone before us on this forum, a #9 has been found to provide the best performance. I believe that is what Acesneights1 is referring too. Regardless what the value is, it is generally accepted that the resistor needs to be there.
 
1994-1995 = OBD-I ... resistor is irrelevant for 50 starts or a TDLearn.
1996-2000 = OBD-II ... resistor difference is noticed immediately. Resistor absence usually results in a no-start.

If I recall correctly. You need to get a resistor. They can be fished out of the existing PMD on the 94s, not sure you have enough room on yours because of the dual thermostat x-over. Easier in any case to buy a new one.
 
Thanks Jim. I will just buy a new one to dig out the old fsd I have to take off the bottom intake its really tight in theRe if I go that far I might as well put on a new IP since everthing is apart anyway. That new #9 res where does it get pluged into?

It fits in the PMD plug slot, it fits around the pins, will only go in one way. It looks like a tiny circuit board which it is. The number on the resistor will face outward.

Minor correction, OBD-II ko/ko or scan tool learn has to be initiated has to be done to notice a missing resistor or one who's value has been changed

So, since I upgraded from stock PMD I may have switched resistors. I now have a 9, and unknown what is in the original still on my IP. In 3 years, I have never done a KO/KO. Or scan tool learn.

Am I STILL running off my previous value??
 
Hello everone lm back and I have my diesel running, my Problem was a bad fsd the black box as some call it, so what did I do wrong after double checking everthing? I didn't plug it in right how you ask? Well instead of unpluging the old fsd right at the pump I traced the wire back up and unpluged it at the top and pluged in the new extended harness so alls I did was unpluged the computer from the fsd DUH. So with a neddle nose and a long screw driver I unpLuged my oLd fsd pluged the harness with the new fsd in and she fired right up. My new friends at the diesel place told me that the truck should start without a resistor. So my next Q is can I mount the new fsd anywhere? And do I need that cooling unit or can I get away without it? Thanks for all your help guys!
 
You need the fsd mounted to a cooler and mount it out of the engine bay. In the front bumper between the nostrils is a good spot.
