Curious. I'm a PMD virgin and my first new one is due here today. Not sure if it'll come with a new resistor or not.

: must new resistors/transistors be used when installing a new PMD? guybb3 08-31-2005, 07:40 AM Depends on where you got it 94blazer6.5 08-31-2005, 08:05 AM I'm not for sure but i think you can run with out it, and the PCM or ECM will deflaut to a #5 resistor. You can do a search for resistor or PMD to find more info. I'm running a #9 and seems to work well with no code to date. Steve93mustanglx 08-31-2005, 09:33 AM the one I bought comes as a kit with a wiring harness included, but not sure if the resistor/transistor (?) is included or not. thefermanator 08-31-2005, 01:39 PM If you run without the resistor the SES light will come on and the truck will revert to a #1 and I believe it will also go to reduced power settings. It's not a good idea to run without it unless you have to. A #5 is normally stock, and a #9 is the largest you can run without the SES light coming on. There is not a real big difference between the 2. Steve93mustanglx 08-31-2005, 03:24 PM can i reuse the old ones or must i buy new ones? w_huisman 08-31-2005, 03:33 PM Re-use the old one. Use a paperclip bent into the shape of a small hook to get the old one out of the pmd. Steve93mustanglx 08-31-2005, 05:33 PM Awesome- that's what i needed to know. Thanks! cretan 08-31-2005, 07:42 PM Where is this resistor located and when do you need to change? knkreb 08-31-2005, 11:02 PM Up inside the wire connection to the PMD itself. It's a flat piece of silicon with a number on it. CanadianRigger 08-31-2005, 11:04 PM Its located inside the female plug of the PMD, a very close look and you will see what number it is, hook it with a paper clip around the corners and pull it out to change it. Its simpler than you think. (PMD must be removed to do this easily). As to when to change it out.... i have no idea!) cretan 09-01-2005, 02:44 PM why would you have to change resistors? CanadianRigger 09-01-2005, 02:56 PM Higher number resistor gives slightly more fuel. Don't think you'd feel it much though. Only reason to change the actual resistor is if it burned out for some reason but i've never heard of one doing that. w_huisman 09-01-2005, 03:08 PM why would you have to change resistors? Steve93MustangXL stated in his post at the beginning of this thread that he wasn't sure if his new PMD would come with a new resistor. If the new PMD doesn't come with a new resistor, then he would need to take the old resistor out of the old PMD and use it in his new PMD. It's not hard to do if the PMD is in hand, instead of still mounted to the side of the pump. cretan 09-01-2005, 07:28 PM So if higher numbered resistor increases fuel couldn't you rig up a variable resistor(pot)to increase\decrease fuel as needed for power or economy? PARKED till diesel price gets below $2.60/gal again! This is rediculous Huisman..diesel here in saskatchewan where I am is priced at 95.9 per litre.Tommorow fuel is going up again 13.0 a litre.I think 3.78 litres is one gallon.so that would equal to about $3.63 a gallon.You are getting a heck of a deal! Steve93mustanglx 09-01-2005, 09:13 PM OK, I pulled the manifold and removed the PMD today. The new PMD did not have a resistor so I pulled it out and installed it in the new one. I used a paper clip and pull a little on one side, then the other until it was out. Very simple operation. Tomorrow I'll complete the manifold reinstallation. I pray this is what my problem is... | ||
