The computer turns on the code when the signal is received from the TPS switch on the throttle body.

Bad neutral safety switch? Engine locked?

Make sure trans fluid is full. See owners manual for proper dipstick test.

If fuel pump is new you should have good pressure before injectors, but check pressure anyway. If pressure is low go back and check for a bad fuel filter between tank and engine and replace. Fuel lines get clogged because of moisture in the lines causing rust. Did you replace the under pump fuel filter? Back to front, if pressure is good , injectors may be the problem. Do a compression test to see if your engine is starting to die. I have only given you an idea of what to look for. You will either have to check yourself ,or have your truck checked by a shop.

Transmission pump.

Try removing the skid plate from under motor then that should allow you to access the bumper bolts. Some of them required removing the grill also. Good luck

Check under seat for object blocking seat movement. Lube mechanism.

Check circuit breaker and wires under seat. Likely bad connection or bad switch. You can pop switch out and check for voltage as use operate it.

Replace stock sender with basic mechanical gauge to see what really up, or take wire from stock sender and ground it to see if gauge comes up to top. If so, replace sender. (NOTE: Do not use teflon tape or any sealer on threads of new sender as this is the electrical path for ground.)

Heater core is under the dash in the same enclosure as the interior fan motor. as to remove/replace, I recommend getting a chilton's manual for your vehicle, they have step by step instructions and specifications. Its a great investment if you want to do things yourself, and if it's too complicated it should give you an idea as to what to expect from a mechanic

There are two things you will want to check: is your vent tube clogged up, and is your fuel filter clogged up? It might be an internal-tank fuel filter.

Illumination could be a fuse blown, broken wire, or bad connection at the plug and dash. Other lights like ABS, Check engine, could be a bad wire/data wire, or bad bad connection at the plug and dash. I fix a lot of them just by unpluuging the plug and plugging it back in the cluster.

GM states this code is for the ebcm electronic brake control module, I have replaced alot of these over the years the motors short internally and the entire assembly must be replaced. sometimes the main abs fuse will pop and you replace it only for it to pop again because motor in side is shorted to ground.
