I had the same problem on my way to Washington state from Iowa. I never checked to see if my throttle valve was dry, but I had it taken to a shop and it was the mass air flow sensor which is a metal cylinder connected to a tube between the air box and the engine. One thing you can try is disconnect the wires that go to it and see if it starts. This is just an idea that may help you.

I have a 2000 GMC Jimmy that has around 93,000 miles on it. The last oil change was 2 weeks ago. Today, on a trip on the interstate, I pulled off to have dinner. When I left the restaurant and started...


If the trucks engine rev'd up when you first put the gas pedal down, but didn't go anywhere then it was probably in neutral (not drive as you thought). If it was in drive and still didn't go anywhere but engine still rev'd up then its a transmission issue or PRNDL switch at the side of the tranny. I can't see anything relating to the gas pedal by NOT reving up the engine when it was pressed down. I wouldn't suspect a throttle cable issue. Check the tranny fluid while truck is running in park, see if the fluid is badly burnt or low on the dipstick. If it looks good I would have the PRNDL switch checked. (Park Reverse Neutral Drive and Low) switch.

Towing a 5x8 trailer with my Jimmy and now it won't start


Is your battery charged if so!!! I would look for the speed control box it is located under the glove box. It is a little white box with a lot of wires in it. this box is with the computer but there are separate box's. It controls everything from shifting to starting to the gauges in your dash You DO NOT have to replace the computer Good Luck

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.
