I had the same problem! Some days it would start fine, some days it would start with starting fluid, other days wouldn't start at all! I replaced the fuel pump in July '08, then in Dec. starting troubles began. I ran many tests and found a few little things like weak coil and battery! The major cause was the fuel pump! Jimmy's '96 and newer require a higher pressure 55-68 psi. Test with ignition on engine off! I just put in a new Carter pump that has good pressure! I also read that the deqaler oem parts work! The link is for the same problem with a '99

1998 jimmy start/stall by rushx15

I have a 1998 Jimmy that I'm ready to roll over a cliff. It starts up for just a second and then stalls. This can go on and on. After a half hour or so it cranks right up. I've gone through everything I can think of. EGR valve, ignition switch, fuel pump/filter. Could it be the security system? That light is always coming and going...

Please help! My car is broken and we are lost on what to do. The car has been "stalling out" mid drive. I was going 65 on the freeway and it completely shut down. It also does this when I am driving around town. We have done the following:
 
complete tune up
new battery
TWO new fuel pumps within weeks of each other
new center port fuel injectors ? or something like that
 
STILL stalls. Today it failed smog ONLY because " fuel evaporative controls functional" area failed The smog guy told me gas vapors are leaking.
 
HELP! I need my car for my kiddos and am soo lost on what needs to be done and no mechanic knows how to fix. THANKS!!!

Does your Jimmy stall when it's in overdrive?

You may have to pull the codes from the computer.
My '91 would stall after 15 minutes of driving. I pulled the codes and it said something like "engine temp. was at 32 degrees" or some sh!t.
I replaced the temp sending unit to the the computer (not the gauge nor light) and all was solved.
What was happening was when the car got up to temp. the Computer temp. sender would shut it down. That was just my situation.
To sum it up...don't throw money at it until you've pulled the codes.
