not sure here as europeon mechanic with no pratical but i would check for a valve on the fuel delivery pipe and this valve will have a vacumn type chamber on it and a vacumn pipe ,On this age vehicle its not uncommon for this valve to fail and will stop the fuel pressure in the feed so it will not fire up .This valve is to stop the fuel from leaking past a injector if the ignition is left on for any reason so check the vacumn pipe for leaks first that control this valve as this is the most common cause of non start .

There is most likely too much play in the shifter linkage. Block the wheels on the truck and crawl under and watch the linkage as someone moves it back and forth from park to low. There is probably a lot of play in it and you will have to get that out. I'm not as familiar with that body style as I am with the pre 88 but it is similar. There should be a threaded part on it to make adjustments. Only turn it a couple of turns and then check it. If this won't fix it then you will probably have to get inventive and make some bushings and spacers. Seems to me that the last time I went to the dealer looking to fix sloppy linkage, my wallet got scared. I used copper pipe to make bushings and washers to take the side play out of joints. Hope this helps.

theres a good possibility that the brake light switch is bad or out of adjustment. it is located just above brake pedal, so when you apply brakes it turns on brake lights. good-day !

What was the fuel pressure?

GM vehicles are notorious for a a having a failed antitheft system thats called Passlock. When this system fails, the key doesnt communicate with the ignition correctly and causes the vehicle to stall. Next time this happens, look for a light on the dash that says SECURITY, if you see this, then this is the problem. Go to this link for info and DO IT YOURSELF solutions to this problem.

Dash lights may be replaced depending on the dash cluster. Most these days are (sealed) and require a (new) cluster. The only way to know for sure is by contacting a dealer. Removing the cluster is not an easy task, by the way. Hope this helps.

check your owners manual and see if you have an inside cab air filter for the heater/air cond. When they get clogged, they restrict the air flow.

Okay the motor for the 4x4 got stuck in 4LOW, Can you accsess the 4x4 motor switch,at see if that will retract the motor and default to 2 wheel drive because the switch itself went bad and wont disengage. see if that will help if not youll just have to by pass the switch and trigger to its normal position make sure its in neutral also

1999 Chevrolet... | Answered on Jul 25, 2011

First check your basics. Check the fuel filter for plugging. It is on the driver's side of the frame underneath the vehicle. The other item to check is the MAF or mass air flow sensor. If there is a check engine light on have it scanned by a local auto parts store for free and let me know what the codes are. Be happy to help further.
