[93hummer]

My suburban is giving me fits, I changes the fuel pump and now it won't start. Since I have owned it, it has always had to crank just a bit (but not a lot, maybe 10 seconds) to get it to start the first time of the day. It is not a glow plug issue, I checked that out, plenty of voltage getting to the plugs. Once started, it starts in about a second the rest of the day. I changed out most of the rubber fuel lines, and it got a lot better. Still, I want ti to start like the Hummer, quickly every time. I have figured out recently that the problem is worse if I let it sit overnight with the engine higher than the gas tank, my driveway makes it sit like this. I thought maybe the pump was bad and letting the fuel drain back into the tank overnight, so I bought a new pump. After installing it I can't get this thing to run at all, it started once then ran for 30 seconds and died.... now it won't start at all. I cracked open 2 injector lines and cranked until fuel came out and got lot's of bubbles coming through the fuel return line (I put clear hose there). It is still not starting, I think I neeed some ether.... it will either start or blow up.... either way something cool would happen!!!


I really need to scrap the friggin fuel pump/filter on this thing and install a Hummer filter/ pump. I have ran the Hummer out of fuel 4 times and each time it was pretty easy to prime and get it started again.. this burb is a nightmare to get the fuel system primed.
