90 model Tracker Won't Start!! HELP!!!

MY 90 model tracker won't start at all. It was fine then all of a sudden i went out to go somewhere and now it won't start. I'm getting fire to the distributor and getting gas to the throttle body. But all it wants to do is crank it won't pickup and start. ANy suggestions? I need help with this thing not sure on what to do next...... only owned it for a few months and its my work vehicle so gotta get it fixed quick!!! Any one with any help I will greatly appreciate it......

Are you getting any codes?

Well double check the fuel but if your getting spark and fuel then do a compression test and a leakdown test.

I've got a 91, did the same thing. mine was the electonic idle control. $250 bucks worth, I took it off and sprayed it with berrymans put it back on and it worked still does. It's a little thing that if your standing in front of your engine looking at it, is on the left side of the intake, I believe it has two screws, 2 vacuum lines and one electric plug. I unplugged mine put a jumper wire between the pins and it sarted right up.
