SOURCE: TPS in a 1998 GMC Jimmy

the tps is ususally at the side of the throttle body opposite where the throttle cable / tv cable mount.
sometimes it won't start, run, or run erratically. there are ways of testing this unit (by output voltage) before you commit to buying a new one. to test it you will need a dvom (digital volt ohm meter).

just a note: straight from the book... "a broken or loose tps can cause intermitten burst of fuel from the injector and an unstable idle because the ecm thinks the throttle is moving."

SOURCE: MAF Sensor and 02 Sensor

Replace the fuel pump with another one.
This is a common issue.
Don't use an "aftermarket" pump; buy one from Chevy.
I just had this exact same issue in my shop. The truck would run for a bit, and then just stop. I had the truck towed in, and the fuel pressure was good. Drove it for a while, with the gauge hooked up and taped to the windshield, I could see the fuel pressure start to drop off. I told the owner that she needed a new fuel pump.
The owner told me that the pump was 2 months old. I went ahead and changed it anyway. A new fuel pump cured the problem.

Testing the MAF and the O2s is not going to tell you anything. A failure, an open or a short would set the check engine light.
Please feel free to get back to me if you desire any further input. Thanks for choosing FixYa for assistance.

Leave 02 sensor alone ,it is doing it's job . It is heated up because of lean fuel mixture due to incorrect engine temp.,replace thermostat before looking further.

You cannot do that because the sensor has a varied voltage output and the ECM will see it as something wrong.

I would like to know where the oxygen sensor is on my 2000 GMC Jimmy. Can anyone help me locate that?

From my research, there are multiple O2 sensors on the exhaust system. They can be found near the catalytic converter, before and after it. O2 sensors are easy to find by the wires sticking out of the exhaust system and the mounting bungs for them.

How many o2 sencor does a 1995 gmc jimmy have

Look at the underside. If you only have 1 catalytic converter then at most you have 2 sensors. 1 before, usually seen when you look at the exhaust manifold near the engine and 1 after the Catalytic converter or on it. If you see a sensor on the exhaust system with wires attached that is an O2 Sensor.
