Old 6.5-T strikes again !

Not open for further replies.
Junk PMD is junk PMD. No saving it. It is near impossible to diagnose bad PMD's, but any PMD that has lived under engine hood is in question of being junk, if not junk already.

SO.

In order to eliminate PMD as THE MAIN PROBLEM of 6.5's, and THE REASON THEY GOT BAD REP to begin with.

You need to buy a NEW PMD and mount it where you have it, OUT OF ENGINE BAY.

Then, you can safely assume that is NOT the problem and it probably never will be again.

I been where you are before bud, got it running, revved her till the limiter stopped it from blowing up because at that time I didn't care either.

I replaced it with a PMD mounted in engine bay. Lasted 3 months there. Chased problems left and right until I ordered a NEW ONE and mounted it under bumper like you.

Havn't had a problem in 2 years.

I fueled my truck up today and my truck weighs 9200lbs. It does not feel sackless, sluggish, or gutless. In fact when people follow me they say that thing really moves. Yet I baby it. I do have 4.10's, but still I have never wished it to have more power. Most I ever towed was about 3,000 lbs. Climbed hills fine. Average working load of my truck is about 9500 - 10k lbs.

I do think once you get this 6.5t tamed, running, and resolved you will not think so bad of her. I have never in my life driven another 6.5 on the road so i have nothign to compare it to.

I think you should find a 6.5 and take it for a test drive to confirm weather yours is problemed, or if you are just expecting too much.

Of course, once you get it running again.

You come off odd at times, but I do understand the frustration.

Now you know why these engines got such a bad reputation.

Not sure if your problem is PMD or not... I had no problem buying a new one because I plan on keeping the truck, so even if it didn't fix mine, I wouldn't have to worry about it again. But it did.
 
Buddy:
So the #9 is for sure with the new PMD ?
But not worth the time on the old PMD ?

Matt:
I am short on funds at the moment i will do the new PMD but i am tired of throwing money at this truck. so i'll buy the PMD n #9 kit if its a good idea to add that on.
But once i start hitting parts that are running $600-$2,000-$3,500 then its time for a new power plant.

Don't get me wrong i LOVE the TRUCK itself, Just me and the power plant aren't getting along so well at this time.
I would rather Repower it then replace it.

My trucks drive train:
6.5-t, 4L80E, GM 9.25" front, 14T 10.5 Rear, 4.10 gears and 7.50-16 tires aka 235/85R16. . .

How many miles on this engine anyhow?

New resister wont fix ur problem. Don't buy one until your ready to buy a new PMD w/resistor.
 
Only 131K !

I ain't even going to touch till i get the new PMD cause if that is whats bad then i am just wasting the life of my starter.

tho i might drain out the fuel when i can get it back to the shop.

If you haven't drained the bad fuel out of your entire system, it will probably continue to give you problems until it is removed or diluted. I would do this first since it is a known problem and see what happens.
 
Not alot by any mean.s

Bring your vin # to the closest dealer and have them print you up a vehicle history.

More then likely your Injection pump has been replaced already via warranty, and it may give you an indication of how many miles are on that.

Mine was replaced warranty at 40k, So i have 80k on mine as far as I know.

That is what is Grinding my gears and making me Angry and is what keeps me always Pissed off, the last thing i want to hear about a broken truck is how reliable it " SHOULD BE " what it should be and what should do ain't always what is DOES !
Mikey


Well you are on the wrong forum then...

The guys here know these trucks and believe that with the proper knowledge and diagnosis of these trucks, they ARE the most reliable trucks...

It's getting old hearing you say the same things over and over...we all get it ... you are angry with the truck and love to complain about it... now it's time to quit complaining and keep your posts to a more technical nature and you will get the satisfaction you seek...

If you'd like to just vent...try off topic...

The 6.5 "tech" forums are for just that...TECH!
 
:thumbsup: Lots of tough guy talk :thumbsup: when your done insulting people and have some help to ofter on the subject then do come back :thumbsup:

:D Have a wonderful Sir :thumbsup:

Mikey
 
thats just fine i was about to get the part to fix my truck and be done with this but thanks for your help you have been swell :thumbsup:

but i am locked and can't do the transaction peace out. ..
 
Comments such as the one above was done to provoke Anger and nothing more or it wouldn't have been said PERIOD !

Mikey

No...You were informed by staff members numerous times to keep your threads to the point and that only tech belonged in the tech forums... your disrespect for the members who try to help you and the staff members who instructed you on how to conduct yourself on this board is what transpired into this situation...
