The line closest to the strut that you have patched is the return line. That line is more suitable to repair since under less pressure. It is worth trying high pressure rubber fuel hose and pair hose clamps on each end to see if that will hold. You may have to replace that line later if the...

Just did this water pump replacement two months ago. GM OEM p/n 2512029 metal gasket is available at rockauto and was delivered in great (flat) condition. Glad I ordered it separate because the gasket that came with the water pump was all bent up. Used a star pattern when tightening bolts and...

As a long shot and preventative maintenance you can try to spray contact cleaner at the cam and crank sensor terminals to ensure the circuit provides clear signals. It worked for me to clear a slight glitch at idle.

When you swapped the donor engine into the '04 did you change out the cam phaser (cam actuator gear) or leave it as is? What year is the donor engine? I ask because the '04 models had the helical spline cam actuator gear which do not have a lock pin and depend on oil pressure to hold full...

Welcome aboard 'TOB'. Even as a mechanic you will find a wealth of knowledge to fix any and all issues from the folks on this site. I certainly have thru reading threads when the typical faults come up. I had occasion to browse more recent model suvs in the same mode as the GMT360 and was not...

Try disconnecting the charcoal canister hoses. Let us know if that works or not.

I was just stating at this point I don't think the purge or evap valves are preventing fuel from entering the tank. The last thing you should try is disconnect the hoses at the charcoal canister next to the fuel filter. It will allow the tank to fully vent so you will pinpoint if the cause is...

The Evap valve hose disconnected should allow the tank to vent to atmosphere albeit through the canister. With engine off the purge valve is closed so changing the purge valve can only help remove pressure (add vacuum) when engine is on. Plus it's not typically pulling vacuum at idle. You said...

@Stuntmanmike1977 have you tried adding fuel to the tank with the C101 harness unplugged so the pcm doesn't get any signals from the fuel tank? Or better yet, disconnect the battery ground terminal then try to add fuel.

The ohm meter is displaying kilo-ohms. Some digital meters actual show a small 'k' to indicate the ohm scale. .580k-ohms is 580 ohms.

Off topic but I found something interesting when filling up my late 2002 ENVOY (June build). The PCM fuel level% is accurate at low level but maxes out at 90% at overfull tank levels. The Dash gage is accurate at both low and full levels. I would think a full tank with correct fuel sender output...

Just to cover all bases, is the filler hose line free of restrictions? I recently fixed a deteriorating rubber hose line causing a small leak when I filled up with gas so I recommend checking for restricted flow from just the filler neck to the tank entry check valve to be sure it is free flowing.

The purge solenoid hose connector toward front of engine with the push tab has a groove that you slide the tab all the way to the other stop on other side of hose. Just have to shift the tab back and forth until it releases.

Found some info on the fuel tank p/n 15229311. It is very similar to 2002-2003 trailblazer fuel tank p/n 15077622 but has more capacity on the front end of the tank. You may have the 22 gal version of the fuel tank so it will work with the new fuel pump assembly.

The purge solenoid default is closed so can be left after tank/fuel sender operation is patched up. A large flat head screwdriver pushing down and to the side of the middle metal tab will allow the release of the purge solenoid from bracket. That tank p/n does not show on gm parts list. If tank...
