1989 gmc s15 2.5 - check engine light comes on - the code states a running lean condition. It comes on and goes off. When it goes off, I'm assuming it's going into closed loop and runs poorly and acts...

Hook up a fuel pressure gauge to the schraeder valve, and then operate the vehicle. I'll bet you will see a corolation between the performance and the fuel pressure. This would indicate a failing fuel pump.

My gmc jimmy isn't getting gas good up to 30 mph i replaced the fuel filter and all the spark plugs

You might have bad fuel injectors or the fuel pump may be going bad. You may also have low compression, therfore you loose power. Is your check engine light on? Do you have any codes?

Power steering full but heavy steering 1997

Okay, for the steering issue, you may have a bad power steering reservoir.

The fuel inction problem...more than likely a sensor problem. If you can get to an auto parts store like Schuck's/O'reilly's/Kragen/Chiefs/Napa...they will read the code for free....I mention this because you say you have the check engine light come on and the hesitation problem sounds like a MAS/MAF sensor...mass air flow sensor problem. Find out what the code is, and they will tell you for free...FREE!!!

My 1996 GMC jimmy wants to stall when I come to a stop. The RPM gage goes up & down then drops below 1000 RPMS and stalls.

I would go down to your local auto parts store and do an alternator and battery test. It sounds like at low rpms you are loosing volts. When you apply the brakes you would be supprised how much power from the engine it takes. You could also be loosing oil pressure. Check your oil level. When your engine drops low rpm, the oil pressure drops and shuts down the engine.

1995 gmc jimmy-won't accelerate wants to stall

could be the fuel pump will need to do a fuel pressure test on it ..the pressure should be 63 anything lower even so much as a few lbs will cause this to happen well if it sat that long i would consider a complete tune up and check all vacuum lines for dry-rot

Driving fine suddenly stoped engine kicks but just wont start.

Have you checked your fuel pump relay. It is located on the panel with the fuses under the hood. If the relay is not working, the truck will crank but not start. This is a typical problem of vehicles that run fine and then suddenly quit. Hope this helps, rate me highly please.
