Hey everyone, I have a 1994 6.5 chevy 1500, automatic, This truck has sat up for approx. 1.5 years, and now trying to get it to run again. Job I know, let me give you a little history on this, the guy I got it from was a second owner, he said he purchased the truck and installed a new pmd, let it idle until it ran out of fuel, and just never did anything else with it as he didn't know how to bleed the lines, and he had another truck, well a few months ago I end up with truck (he owed me money)thinking, a set of new batteries, added fuel, and new fuel filters, a touch of eather, and varoom, well only if I really had good luck, but here goes, new batteries, and a touch of eather, and we cranked up just fine, yippee, took it for some short trips, around property, and all seems well, decided to take it to town, on open road, and once around 60 or so, it sputters, and dies, figured trash in line from sitting up, cranks right back up and again, we try to go about our way, and a few minutes later sputters and dies, well this time looking around we find bad fuel leak, seemed to be from back of motor, so towed it home and look for issue, cannot really pinpoint leak, so we get new filter, and re do it, no go, then researching, find out there is a valley where the fuel is more than likely gathering to pour out, so off comes the intake, don't see any visible leaks, but change orings in filter canaster, and all rubber fuel lines, and intake back on, upon bleeding the air from the system, and checking, luckily no more leaks, system dry, start up with a touch of eather, and sputters a bit and dies, again sputters and dies, (expected) then she cranks with no missing, sputtering nothing, sounding like she should, let it sit in yard and idle, for a while, a pop or two initially, then smooths right out, temps look good, fuel pressure looks good, all systems go, down the road, plenty of power, but some light issues, and back, no misses skips, and no leaks, thankfully, well after idling for 5 mins or so, back down the road, not to get 2 miles from home and she shuts down, no sputtering, no spitting, just like the key was shut off, any ideas anyone, and the starter needs to be retightened, so I just came in tonight,

Please help, need a way to go, as my f150 died,

 

I had almost the same problem on my - 95 gmc and it was the lp that failed,well not the lp but the oilpressure switch that makes the lp work when the engine is running.If your truck is build the same way as mine you can check the lp by get shifter in Drive and try to crank it,in crank position you hear the lp ticking to give fuel in starting moment and then when it has started the oilpressure switch is supposed to give power to the lp.

 

thanks, will check this when the sun rises and rain goes away, will let you know,

 

if your dash go's dead but blower motor and radio work when the truck dies, you need a new ignition switch

 

You can jump the lp and bleed the fuelsystem.If it starts the injection pump is supposed to hold the engine running by it self,if it's in pretty good condition.I guess the lp works,if not you haven't notised the leaks at the filter.Maybe it suck's air somewhere,check fuellines under pressure.

By the way,Check racer55's answer in this question. https://www.dieselbombers.com/chevy-...y-running.html He has a lot of smart solutions

 

Keep spraying a 6.5 with starting fluid and you will have 2 dead trucks use non-stick cooking spray instead or WD-40

 

only needed the ether for initial start, it starts and runs fine at an idle, but put it in gear take it down the road, and in about 15 to 20 mins, it just dies, like someone turned off the switch, but lights remain working, no smoke, no missing, just dies, but however it cranks up just fine, after it dies, the oil is really really dark, and did lp tests seems to be working fine, but havn't done one with the truck in drive yet as the weather decided not to cooperate today, plan on doing it first thing tomorrow, and will let you know, thanks everyone for your input it is greatly appreciated

 

It might be the pmd that cause this problem,they can behave strange before they shut of compleatly.Is the pmd moved from ip to a heatsink? In that case check the conections,there's a lot of bad cables in market.If it's not moved,move it to somewear there it get's cooling.Heat diesel for example can help you with parts.

 

I must be the only GM owner to have the Ford fuel tank problem. I have read many posts but do not recall reading anything about BioDiesel causing fuel tank problems on the 6.5's.
I used to buy fuel at the same station all the time. The station switched to BioDiesel. After about 6 months my 96 GMC K3500 6.5L began to shut down on me. I eventually found that the inside of the tank had "delaminated". There were silver flakes floating in the fuel. Looked like silver paint. The chips would clog the strainer and my fuel supply would be cutoff. Refilling the tank washed the flakes from the strainer and fuel would flow freely for awhile. I had to replace tank, pickup and sending unit, lift pump, etc. I now look for fuel that is not marked BioDiesel, but am experiencing similar problems again. I have a remote mounted pump driver, but after having replaced the lift pump and filter, thought I would try a new PMD instead of dropping the tank.

 

finally right bolts for starter, yippee, don't go to parts store, they will send you home with the wrong ones, lesssons learned, going to get oil pressure switch, filter, and oil, will let ya know outcome
