6.5 diesel chevy p/u dies, stalls suddenly!
i'm new here just found site my chevy p/u dies, stalls suddenly its a 6.5 turbo diesel
any thoughts on why? |
well are you getting any codes and when stalls does it start right back up could be bad PMD ,LP or OPS that cause that or sucking air if fuel line need more info to help you out
|
fuel pump on frame works but no fuel to injectors.
no codes. |
My 95 did the same thing. I took the pmd off and put some dielectric grease on it. hope that helps.
|
what yr is your 6.5
I would also check fuel shut off Solenoid make sure it working Check all your grounds they play big part with these trucks there is 2 or 3 grounds at right back on intakes bolt and the there is grounds straps right under a/c dryer one goes to back of head and other goes to the frame then there one for PMD on top IP and one off the right battery to the fender Here reading this maybe some help to you www.AccurateDiesel.com - PMD Installation Instructions - Accurate Technical Services, LLC |
1995
dielectrical grease didn't help solenoid clicks grounds good |
If your PMD is on the Pump, it's probably dead. As a 6.5 owner....carry a spare.
|
what is the best pmd kit?
|
this is where i got mine PMDCABLE.COM and i got a turbo boost bolt here also. It was a snap shipped fast and had not problem ever thing worked just like it should
|
Leroy Lenza who owns pmd cable .com is a real good guy and ships stuff same day. I was having some problems with a cable he sold me and he spent a good deal of time on the phone with me to get it sorted out. I bought a Stanadine pmd from him and relocation cable and my truck has run real good sense then.

'99 6.5T lacking power
My '99 GMC K3500 Crew is suffering from a loss of power @2000rpm. Recent (within last 8-10 months) changes and maintenance includes, PMD relocator kit w/heat sink and #9 resistor(SSDIESEL), new lift pump, wastegate solenoid, OPS, larger downpipe, marine injectors,glow plugs, in-tank strainer and fuel filter strainer. TRUCK ONLY HAS 105K on it, purchased it with 84K on it a year ago.
Original reason for changing glow plugs was hard cold starts, rough idlling, and surging. Now I'm lacking fuel in the filter with a second NEW LIFT PUMP. Truck only stalled once after a hard acceleration and stop. Could a bad vaccum pump cause this? My ABS light comes on and off sometimes and its hard to press the brake pedal when that occurs. |
Let me know how you make out on this. it sounds like i am having the same problem. but mine is around 2500 RPMS. I have done everything you have done beside injectors. But i did a few more like clean grounds and mine has a new IP

'99 6.5T lacking power
I sure will let you know. Let me ask you this; Where are all the grounds located on the engine? Is there a diagram of this available?
---AutoMerged DoublePost--- What causes a lift pump to lose power @2000 rpms? Is there a relay for it? I'm not familiar with the electrical details of all diesels yet, more specifically my own, but I will be by the time I figure my rig's issue out. |
JASDONDUKES- Check your other posting "6.5T misses"; I posted a lengthy reply about my situation now. It may help you out. End result is a faulty 2 wks OPS I guess. Makes no sense to :argh:me.

The OPS SAVER installed with only 1 splice and the a1customs.com products are of much better quality than expected, looks like factory stuff probably better. It may cost more than the cheaper stuff but the quality is there and i want only the best stuff on my trucks the PMDs are expensive and i don't think it's a place to cut corners on cheaper stuff because having to replace it again costs more than getting the good one designed to last in the first place. |
6.5T loss of power@ 2000rpm
Well after that last troubleshooting post, I still have the same results; HICCUPS, AND POWER LOSSES @ cruising speed:td:. My fuel bowl is only 1/4 full as opposed to when it use to overfull before I had any issues. Any advice or suggestion would be greatly appreciated.:argh:
DONE: REPLACED "SOCK" in tank REPLACED FUEL FILTER STRAINER(UNDER FUEL FILTER) REPLACED OEM injectors with MARINE INJECTORS REPLACED LIFT PUMP 2Xs. REPLACED OPS 2Xs JUMPERED LP and condition still exist. TO DO: drop tank again and see if there's any interence with the sock; New sock mounted diffferently on sending unit from OEM piece. Possible problem with placement inside tank. ---AutoMerged DoublePost--- What exactly does the OPS saver do? Why do the OPS' fail so frequently? |
sounds like it could be sucking air from a small leak somewhere.
did you test fuel pressure?
