#250 of 301 scratching my head by tcarr22

I have a 2001 jimmy and i purchased it from a guy that said he had replaced the fuel pump last year. It seems as soon as the check cleared i have been having problems with the jimmy starting. It does seem to be a bit of a gamble though because it will some times go weeks with no problems but then on other days my wife will call and it won't turn over. A quick fix is that I can jump it with my truck and its fine. The reason i said the fuel pump was replaced is because I found a instruction manual in the glove box talking about the GT280 installation process. I have done some research on the GT280, could it have been installed incorrectly or is it possibly be a grounding issue. My brother is a Caterpiller mech. and I have access to a lift and endless tools but i need some direction to look so found you guys please anything to help would be appreciated. Also, when my brother hooks up his diagnostic unit, the unit doesn't recognize the jimmy, at all.

When she runs - she runs great ! I have changed coil and ignition module, using a grounded spark plug to test spark #2 wire - spark is yellow and intermittent. Dist and rotor look good, plug wire ohms out around 68k. Cranks fine, recently changed fuel pump asm and corrected whacky fuel gauge - was running fine since then. Anyone have a suggestion ?
Thanks

and does anyone know if you can rent a code reader at O'Reillys or fleet farm?

Go find an HONEST Stealership.
Do you think ALL SIX fuel injectors failed at once?
I don't.
These dealers look at their OWN WALLETS not YOURS!!!

My Jimmy seems to get clogged up sometimes and it will act like it's going to shut off but never does. Usually if I hit the gas it will unclog it and there will be a little bit of black smoke come out of the tail pipe and a bad smell (like the smell of matches). I don't usually have any problems getting it to start up. But this morning it decided not to start at all and my husband can't figure out what's wrong. Anyone have an idea of what's wrong with my baby? PLEASE help!!

#256 of 301 Jimmy stalling out by merrillt

I was wondering if I could get some input. I bought a 1998 Jimmy from a friend of mine. He told me that it ran fine before he parked it. He also told me that it had been sitting in his driveway for about two years, just sitting. It would not start so I replaced the battery and also replaced the fuel pump which I thought was the only problem. Also replaced the fuel filter which was clogged. It's been in the shop for about three months and my mechanic is having a lil bit of a problem trying to figure out what exactly the problem is. While it was out of the shop after having the fuel pump replaced it ran fine for awhile, and then it started losing power as I was driving one day. I sat on the side of the road and it would start back up and throttle up and then cut off. After sitting for a few min it would start back up and drive a lil bit before losing power again. My mechanic thinks it may be the spider fuel injection system...any suggestions? Also is there a way to clean/unclog the spider fuel injection system if that is the problem.

Vacuum leaks? Mass air flow sensor? my 96 would idle high and want to die when i tried to drive it and all it was is the air intake at the throttle body wasnt seated right letting air skip the sensor.

Hi, this is a first for me but thought i would put my two cents in.. I had same prob. I replaced the injectors cause i thought it was pressure regulator and of course that was a bunch of money wasted. Talked to guy at dealership he asked if i had changed the NUT KIT???? New to me.. what happens is this is the fuel line that goes through plenum, sure spelled wrong, and attaches to the injectors. They leak after time and flood the engine out and after a little while the fuel is gone and it would crank right up.. Hope this helps.
