used a FASS to replace a airtex, that's been pumping for years,, no issues. OPS mod done, when that pump was installed. Feels like I have 3 lift pumps running now, as to how the truck runs now.

hey fellas,,,, I'm still around like a doughnut, this past Friday eve, I torn into the Burban for a Fass install. Drop tank, remove sock, install pre filter, pump, wix 30micron spin on, then up to modded FFM. < What a pain in the A$$ to get that tank out. pulled straps, and she was stuck up...

anyone running a program on their phone with the Adsl cable to the truck?

I was able to get a Tech-1 from a friend of a tech I know. Hooks up know problem, and boy have a I learned a few things about my rig. I was able to do the ABS purge function a few times, after I vacuumed out the Master, and refilled. I replaced my IP with a supposed good one, but got codes...

I too have been having the no connect issue. The free version would work for me 50/50,, Then after swapping IP, I needed the relearn,, so I pony'd up and paid for full version. It has Never connected for me since. I even reformatted my, yes 10yr old lappy with Win 7 pro, and Only new...

I'd just buy one from Quadstar for under 800 and be done with it.

Locate and clean ALL Ground wires. Is always the first step.

Just got my Email with license for GMDT Tech. :) Let the fun begin!

how much per 43 gallon tank, are you willing to add, either Straight Non Detergent 30sae,, or low ash 2 stroke oil to lube it up a bit?

Yeah,,, I followed along with AK on his thread,,, and I do believe a new Powermaster is next. You never think starter, when you pour half a bottle of water on the IP, and it then fires up. It'll have to wait for a bit thou,, School bus drivers don't make any money in the summer, and the wife...

It's running better than on the old pump,, but it also sounds like I need to pony up for the Pro version of GMTD software to do that. $106.77 is the price today.

look above. The timing marks are almost perfectly lined back up. 200k on engine, so I'm sure it's off some from Tchain. I have GMTD basic,, It shows what I have now. or what the ECM is thinking anyway.

yeah,, now worried about that starter,, it's only a 4 yr old Napa New unit,, but still starts with water on IP. I tried the acc pedal to the floor for 45seconds+, with key on,,, then minute with key off, the restart. Timing in scan tool, never changes. Truck does nothing to indicate that a...

would this current timing,, be far enough out of range that it can't do a re-learn and I need to retard the IP to get closer to the optimal window? Also watched my cranking rpm it was barely over 100.

Finally got the Scan tool hooked up. I tried several times to get the TDC offset learn process to work, to no avail. I had 1 code but cleared that, and confirmed no codes. Tried it 3 times before this screen shot, then once after. Nada. Any ideas?

It's alive and running,,,,, BUT!!! See The fitting with the O-ring? That goes in the top of the IP. then the angled fitting goes on top, and The new 3/8 fuel line goes to it. As I was purging system with air, via jumping the fuel relay under hood. I opened the fuel filter first,,, then...

Old timing mark

it's been 2 summers now, that I've had to "Give the Burb a drink when it's hot out, so she'll start" I got a used one with very low miles a few months back when it was cold. truck seems to run fine with current IP, just with heat soak it get's hard to start, and won't at times unless you do the...
