    Okay Guys, finally quiet raining here so I was able to work on the 95 Burb again. I got the 2' of clear line put on. Got to remember this burb sat for a day or two without being started. I had my Son start the Burb up and it ran like like a million bucks. There was no bubbles in the sight...

    Buddy, Great thread about VW_Lopo. Mine has about 220,000 miles on it also. 95 burb and in Wisconsin they like to use alot of salt in the winter so you might be onto something here. The only thing different is mine doesn't get any better when I loosen the fuel cap. I did clear the codes...

    Truck Runs Real Rough, Please Help

    Okay Guys, I changed the filter, The one that was in it was for sure all used up. I took it for a test drive and as soon as I would give it half throttle or better it would run real rough. Once I was able to hit passing gear where the rpms would go way up and it ran real rough again. One of...

    Truck Runs Real Rough, Please Help

    Okay just got back from doing some testing. I put a meter on the DLC connector on pin f and grounded the other side to check for voltage at the lift pump. All this was hooked up so I could drive around and watch for a voltage drop at the lift pump. It stayed at a constant 12 volts no mater...

    Truck Runs Real Rough, Please Help

    Sorry for being brain dead, but I just want to make sure I get it right so I don't create a dead short and burn something out here. Buddy, I reread your posts and it looks like I could put a 12v power source to pin f and that would run the lift pump? If that is true would you know where a 12v...

    Hmmm, or would I need to put a jumper wire from pin f and go to ground? That would make the lift pump run?

    Truck Runs Real Rough, Please Help

    Thanks Buddy, I was just researching the f and g pins. Do you know where I might find power under the dash near or at the DLC connector? I am thinking of making a jumper wire to the f pin on my 95. I would need 12v power and connect it to the f pin correct? That would make the lift pump run...

    Truck Runs Real Rough, Please Help

    Sounds good buddy, So your saying that if I took a voltage reading on that connector under my dash, where the code reader would plug in, I would be able to get readings from that area? I could take my meter and place one probe on a ground source and the other probe on pin (g) or (f)? And those...

    Truck Runs Real Rough, Please Help

    Sounds good Dave, I was under the impression that there should be some vacume in the tank. That negative pressure is there so the fuel doesn't foam up and then the foamed fuel would get sucked up and end up at the injection pump causing running problems?

    Truck Runs Real Rough, Please Help

    Guys,Thanks for all your great ideas. What I did this morning is I took the fuel cap off. There was air that whooshed into the tank which I believe is normal. I then just screwed the fuel cap on 1/4 turn so I don't create a vacume in the tank for now. I then got an empty clear container and...

    Hey Guys, My wife was driving our 95 6.5 suburban home from work this evening and said the truck started running rough all of a sudden at high way speeds. The oil pressure was normal and the water temp was normal so I told her to come on home. She got home and I pulled the codes via. the...
