New Gray PMD Failed after 11,000 Miles

BTW Leroy, can you still get the Black Standynes ? I have had much better luck with them and as far as the Grey ones.....Well I played Guinea Pig with the D Tech and lost. No desire to go grey until a few years pass and they are proven. Atleast with the Black ones, I know what to expect...."help. My truck is stalling and GM says it needs a new IP...." :rof:

New black stanadynes are no longer available from my suppliers.
 
That sucks the grey PMD failed already. I was hoping they were going to be better.

After my little scare of the truck not running (originally thinking it was a PMD, turned out to be a passlock module) I already picked up a spare to keep in the truck.
 
For both of mine I carry spares just in case, even though the 2 Heaths have yet to let me down 6 years on the truck so far and 5 years on the burb, vs 3 fails under hood on IP & under-hood DSG/Kennedy finned heat sink remote (2nd on intake and 3rd on driver side fender) in same 1st year and a half of ownership on the truck.

A couple of dead PMDs I dissected trying to figure a better way to repair vs replace; had bad mechanical solder joints for the transistors where I could remove the transistors from their sockets as if they were never soldered in the 1st place, so quality of assembly are part of some of the failure modes to these.

I gave up trying to repair them as you do as much damage trying to remove the conformal coating/potting of them as the initial fail mode does of making them useless except as paperweights or conversation pieces.
 
This time around I think the Stanadyne is proving to be better. Only one fail in all I have sold.
The Dtech/Flight systems were good up until about 8 months ago. They have had a big rash of failed in that time. Before that they seemed very good.
 
I was glad I got my D-Tech almost a year ago. I say was because a few days ago I had a slight surge at idle rolling to a stop. Hasn't re-manifested that issue since but I'm ever vigilant now. The SSD unit I purchased years ago and immediately mounted to the bumper with Leroy's cable never did that. Older Flight System's unit?
If it happens again I'm swapping them back and the D-Tech becomes the spare until I scrape the $$ together for what, a Grey one with the mandatory adapter cable?

ive had a grey standadyne on the pump for a year since ive been two lazy to pull the intake to switch back to my older dtech mounted behind the bumper. its been working perfectly so far with no problems. im going to switch back in a month when i install my F intake manifold but im very pleased with the new grey one so far
 
a Grey one with the mandatory adapter cable?

I can make the grey cable now for the same price as the black. I bought a bunch of inventory and got better pricing. The web site says $75, but contact me for an invoice for $39 on the new ext cable.
 
x2 on the "w/Grey PMD" question. I'd mount them side by side on the heat sink with the cables run parallel back up to IP. Easy Swap if needed with my intake set up. Poor wallet, getting flatter by the minute with all this "Forum-itis" I'm catching of late!
Oh, and screw Pay Pal, I'll send you a money order from USPS, it will be faster!
 
Im working on a new supplier for them. I will have to wait to put out a price until I hear back from them.

Paul your echeck still has not cleared!! Supposed to clear tomorrow according to PP.
 
would you need 2 cables, or just switch which PMD one cable is plugged into. Maybe put some tape over the PMD connector to protect the one without a cable from the elements.

I could suppy the empty connector. You can fill it up with silicone and use it as a plug for the PMD not in use.
$8 shipped.
 
Thanks Leroy,

:rant:
No argueing with a bank or even Pay Pal. Its like the statement says, "This isn't Burger King, you take it our way or you don't get [it]!" But I'd still raise hell with them. Like I said, next time....

FedEx just got off their collective butts and updated their site for my RockAuto stuff that was supposed to be here Saturday but has been listed since Friday as having left GA on the 17th.:rant:

I can wait on the Grey PMD till you get the supply source worked out.

I can save some money up in the mean time....:rof:
ya right!
:haha:

Yes because the Gray PMD uses a different connector than the Black ones....at least on my 95.

This is What I'm in the proccesses of doing also...I bought a couple used PMD's for Backup and new cable and Heatsink.....my current Heatsink is not big enough to house 2 PMD's......and I dont think I would want to be Heat Cycling my reserve PMD...Just in case.....
 
I would just run the cable for the Grey PMD as a second extention parallel with the current one back up to the IP. That way I don't worry about road debris contaminating the PMD connector and in the event I need to make the switch, I don't have to run the cable on the side of the road, in the mud and or snow which is when it would go south, on the worst weather day in the dead of night furthest from home where the cable would be safely stored.... Just a matter of swapping which one Fuel Solenoid harness plugs in to, like switching out from the original PMD on the IP to an extended harness for a remote. Except there would be two harnesses to choose from.
No worries about protecting it under the hood. I'd come up with something aesthetically pleasing like what Leroy offered; I could get creative; black electrical tape as was suggested or position it with the openings down and stupidly take my chances (joke). So long as it is weatherproofed and can resist the temps that reside in there, it will be fine.

This is good info. I'm getting concerned about my PMD. I put a brand new DTech on less than two months ago and have already had several throttle blips happen. The PMD is behind the bumper on one of Leroy's cables. I just need to come up with the coin for a Stanadyne for backup.

Werent you recently having alternator problems, battery charging and starting issues? Did you have to jump it at all?
 
That was back in Oct-Nov. The alt was working but not keeping the batts (brand new in Oct) fully charged. I switched to a CS144 alt and now no more charging problems. I only have a small batt charger, no quick start charger here, though I did jump start off other vehicles several times before resolving the issues. I took an almost new GR starter off an 83 6.2 I have and put it on my 94, what a difference in cranking speed. I then rebuilt the old starter, even though it was still sort of working, and put it on the 6.2. Cured the slow crank issue on the 94 and the rebuilt starter is now working good on the 6.2.

The PMD issue was about early Jan. It died out on the freeway (had already had multiple throttle blips and one race incident) so I had to tow it home. I already had a PMD extension harness since the one on the pickup was an all black wire item, making it suspect. I ordered a new PMD and put it and the ext harness on to get it running again. Later I got to looking closly at the old black wire harness and found a wire had come loose from a pin, cheap chinese junk. Now the new PMD is making me nervous and the multiple reports of new PMD failures doesn't help.
