Hey, thanks for the info. It was definitely the pump that took a crap. The new one rumbles along without much noise and is delivering fuel nicely. The Hummer is a gaspot. Just the little one with the 5 cylinder. POS for power but a comfortable ride that will go nearly anywhere it's nose...

Hey there ! Nice guns ! Welcome to where you can get help with diesel problems, talk about current events, and be highly entertained at times !

got it done. asked for the 93 pump but the dealer didnt have one in stock and said it would be a few days to get. bought the one for 98 for now. all fixed and purring like a kitten.

guess i'll take the hummer tomorrow instead, pick up the pump and install when i get home. sucks ! thanks for the advice ! may have saved me from a tough day !

OK.. Sounds good. Its all flat along the way to town so I should be good then. I'll do a quick check in the morning on the OPS to make sure the pump is getting power to it and not being cut out by the OPS failing. It was getting pretty noisy lately and I figured it was getting to the...

OOOOOH, Hats too ! That's cool. Hey, whatever the shirts are (and hats) for price, I'm in !

Well, here's the next few bucks needing spending !! Sounds like my LP went silent. I knew I should have bought a spare to be prepared. Now I have to wait to drive it cause I dont want to starve the IP. It's only 15 miles to the GM store, but should I risk it or should I be fine? Truck...

I'm in for a large. First time on site and I get my issue looked after... it's the least I can do to let others know about the site. Just need to know how much, where, how and when to pay.

Good call. A pyrometer would be a nice touch for the heavier hauls. :firedevil: It's only a K1500 so I am limited to load capacity, but we do have some good hills to pull.

It's all just a matter of the cash to do it up right ! Now (thanks again to evryone here) I have a good base to work from. First impressions are not always the best to end up with; i.e. keeping factory May as well take the advice of all who have previously experienced the shortfalls and oem...

Just wanted to let you know, I cut out the cat, made a turbomaster from the original vac pot (using instructions from the post), and installed a boost guage. RESULTS: WOW, cat was plugged solid. It had about 1/4 to 1/2 inch of hard baked soot covering the insert. I had to chip it away to se...

I guess I just think engineers have some knowledge. Also though, the govt boys tend to make them do things that turn out to be STUPID. This is a good site. Lots of good guidance ! I am a believer...:thumbsup:

thanks for that. found in trl looked at heath's pcm. not a bad deal to get away from egr system. keep it simple, right? get rid of the junk ! wanted to stay factory but factory seems to be the cause of alot of grief for me and others.

well, changed the mystery gasket tonight and now get limited rpm even when not in gear. seems to build pressure inside engine to a point and holds itself back from revving up all the way. i can get it to 2k rpm, lots and lots of smoke. worse on power in gear than ever. seems the gasket fixed...

oK, I know the mystery gasket location. Perhaps this is why I get the bucking when egr vac line is connected as well (?) what does IIRC stand for. it is not listed in the TRL. Also, reflashing the F truck PCM... dealer does this or what?

makes sense. I will try that. also cat gets burned this weekend via plasma cutter :) I'm installing boost guage too. Best way to delete egr ??? any suggestion to override effects on cpu? i dont want it thinking something is wrong if it cant see the egr active. no worries here on...

you bet. stiff haywire wrapped a few times round to ensure it was like being bolted or welded in place.

Hey, thanks... I understand the boost requirements and action. That's pretty straight forward. I have wired closed the wastegate, turbo spins over fine, yet black smoke like crazy and still no power. I fully expected to get the results you speak of but did not. basically there was no change...

OP ?? never mind, i figured that one out. Original Poster .........

I'm considering the egr delete or f intake. exhaust is factory but most of it had to have been replaced a couple years ago so i will likely leave it except the cat. the cat will be cut out this weekend unless there is a sensor of some kind on it. if there is a sensor it will get a replacement...
