P0138 is a code for an unexpected high voltage in the post cat o2 sensor on the left side (bank 1 sensor 2). It often is a result of an internal short between the oxygen sensor heater and the actual oxygen sensor. I would clear the core and if it returns replace the sensor.

96 tahoe keeps blowin the dash ,parking and courtesy door lights fuse


That;s fuse #4 check brake switch to ignition do you have curse control that will also come into play .
What you really need are the factory manuals and a meter or test light to track this down .
A company called HELM .COM prints most factory manuals for most vehicles .50 to 100 dollars you need them to fix especially a 96 Chevy that's the first year OBD 2 they tend to have design problems and are hard to work on .

1996 Chevy Tahoe liftgate not opening


You have likely got broken wires where they come out of the cab and into the liftgate. pull back the rubber and check them at that point.

Chevy tahoe 96 will not start. I have replace the electric fuel pump and that is working. Truck will not turn over.


Hello,

If the engine is not turning over, you most likely have a dead battery, or your starter is bad. If the battery is going dead, you will hear clicking sound and the lights will dim. If you have jumper cables hooked up between the Tahoe and a car that is already running and it still won't start, I would remove the starter and bring it to a place like Autozone or Advance Auto Parts, where they will test it for free.

I hope this helps you!

Po138 where do i start testing for the problem and how


Bank 1, sensor 2. Confirm which bank is 1 on your engine, and it will be the one after the catalytic converter. Normally replacement fixes problem, but try pulling electrical connector to it, apart & cleaning well then retry, just in case only bad connection. Part store should be able to confirm which bank is 1 on your engine.

'96 Chevy Tahoe won't start


i had similar problem. hard to start in morning but once started, would start everytime until next morning. i changed fuel pump, filter, fuel pressure regulator, coil, cap, rotor, pickup coil, battery. i was finally told the '96 had a recall on the fuel injection assemby. i changed that out with the new mpf system and it solved the problem. runs like a striped ape. hope this helps.
