Question about 2000 GMC Jimmy
Hey guys it's been a while, Jimmy's been running great until now...... My thermostat was finished so I changed it, went off without a hitch, so I thought! Now she starts for about a second then dies??? I don' understand? Does anyone have any idea what could could be the issue? Any help will be greatly appreciated. Thanks.
If you unhooked your battery you should check your cables and make sure they're tight, it could just be a loose ground cable.
other possible problems are:
1. something wasn't plugged back in
2. coolant levels are low
3. or the worst possible scenario is that the timing belt broke which would cause the engine to over heat and depending on the year of the engine you've destroyed the top of the engine and it will all have to be replaced.

Have you hooked up a fuel pressure gauge to the test port on the rear of the intake, drivers side. You can get a fuel pressure tester for about 40 dollars at a part store. It is a real good tool to have in your toolbox. If your Jimmy can't build 55 psi, it won't start.

SOURCE: 97 gmc jimmy will not start.
Did you also check the ignition system?? Best trick to find out if you have fire on the plugs is to pull one out, put the wire on it like if it was still sitting in the engine, hold it with the threaded part touching the engine so it will be grounded and able to make a spark, and have a friend turn the key inside and try to start it. If it does fire up, ignition should be OK and the problem should reside in the electronics side of the engine. Which means check the Idle Air Control, Throttle Position Sensor, Mass Air Flow/Pressure sensor, and last but not least, the onboard computer.
