Okay, before you change the fuel pump, get where you can listen to the fuel tank and have someone turn the key to RUN, not start, and see if you hear the fuel pump run for a second or two and then stop. The fuel pump runs a "prime" cycle to pressurize the fuel system before starting. Once the engine starts, a different circuit kicks in and keeps the fuel pump running. The clue here is that if you shoot starter fluid to it, it starts and then runs okay.
 
Another dirty little trick; if you do not hear the pump "prime", take your foot and kick the bottom of the fuel tank. Don't try and cave it in, just give it a good thump. Then cycle the key and see if you here the pump prime, and start. Common failure in GM fuel pumps for years is that they get "stuck" and won't spin up. Give 'em a good thump and they will work again. For a while. Once they get to this point it's time to change them out. I have seen this on pumps with less than 50K miles on them.
 
Good luck

We had a lot of that abs/brake light. stopped in the middle of Road crap. And no one could fix it. after a tip from a friend to unplug all cables to computer (right side of engine) clean them with a electric cleaning spray and use Di electirc Grease in the connections. I used large wire ties around plugs and the computer to make sure they were tight. No more problems after 2 years of nightmare a little grease and some wire ties Good to go.

I have a problem getting the pan down after taking out all of the hardware and removing the cable. The pan will not move forward at all. the front will drop but something is holding it from moving forward. What could be stopping it?

#515 of 535 2000 gmc jimmy a/c question by moooose102

Aug 02, 2010 (10:41 pm)

late this spring, the a/c quit working on my truck. so, last week i bough a couple of cans of r134 (one with oil, stop leak, leak detecter die, etc.) and installed both cans. the fill kit came with a guage attached. anyway, the decal on the heat/cooling duct says the system takes1lb 12 oz.( 28 ox) the 2 cans i bought totaled 36 oz. the a/c works fine at an idle, it will sit there all day with no trouble. but when i rev the engine up even just to 1500 rpm, the pressure goed below 30 psi snd the a/c compressor is electricly shut off by the pressure switch.. is this normal? or should i buy anothe small can of freon, and try adding more?
