Your ignition coil is going bad. Or at least the wire to it is. Start the truck in a shady or dark area and watch for sparks around the ignition coil. If you see some, give it a tune up, plugs, wires and cap and rotor. If you don't see any sparks, give it a tune up and also change the coil. Good luck.

Hello people i got a gmc 99 jimmy 2door sls the engine light keeps coming on then going out ive coded it to be an iat sensor and also says the iat sensor intermitten voltage high and then the knock sensor...

the IAT may be bad or the connector is bad, real common (friend should know to check that) get a real scanner and see what the IAT is reading, then move the connector and see if it changes. if it reads -40f then its bad or disconnected.

Doesn't want to start, acts like it isn't getting

Fuel pump, fuel relay, fuel regualator, fuel injectors, camshaft positioning sensor, fuel filter, etc. Need special tools to diagnose properly, do you have them? Doubtfull, I don't have all of them and I've spent thousands on my tools. I can do a guessing game with you but I prefeer not to lead you astray.

I have a 99 gmc jimmy and the starter will not do anything.The batt is full charged. All I hear is a one time click in the fuse block under the hood each time I try to start it. thank you

sounds to me like the starter motor solinoid has gone so you need to replace the starter motor

if this helps please let me know

What size engine? You need spark while cranking and fuel pressure thats the basics we can work from there.

My '99 gmc jimmy has a clicking noise inside the engine. the oil is full and it started after taking a long trip.....400 miles

Your valves need to be re-shimed  If your motor is the 2.2 the problem is quite normal.  Expensive to fix but normal.  You can sill drive the car fine.
