I Have a 2001 GMC seirra 4x4. It is a good truck and has been realiable for me. Just this morning I started my truck and drove to work about 5 blocks. About and hour later i went to go home. I started my truck and put it in reverse as i started to back up my truck started to sputter and lurch then it just died. I started the truck up again and it started just fine. I put the truck in drive and when i put my foot on the gas it started to sputter lurch and then died. I thought I might have water in the gas so I went and bought a bottle of antifreeze gas whatever it is(heat). clears up the water. I didnt have a full tank about 1/4 and waited about 2 hours. Now the truck wont start at all but it turns over. Please help me.

will it turn over ? newer gmc's have an idiot safty thing... it wont turn over if the fuel pump cant put out enough presure, good chance its that especially if you use regular... try to find someone with a computer to see what codes pop up on it.
When your replaced the pump did you replace the fuel filter? You may have a fuel pump relay causing you some grief. I believe it is located in the engine compartment in the fuse center on the left inner fender. Check the relay and any related fuses. Check the electrical connection at the pump. They had problems with some of them and they would get kind of hot and distort and corrode. They have new updated ones that can be easily installed.
Replace the coolant sensor on the front of the intake manifold.The coolant sensors on this engine does go bad and wont set a check engine light. The sensor will read about -32 to 0 degrees when they do go bad. The computer thinks it is that cold and sends tons of fuel to the engine. If you try to start the engine with the throttle depressed to the floor it puts the fuel system in clear flood mode and wont fire the injectors. Engine will start then and run very rich. The coolant sensor has two wires on it and sometimes you need to replace the wiring pigtail going to it as the sensor can seep coolant into the connector and corrode the terminals. All the parts are available at pepboys and autozone or napa. Good luck
To reset the oil life......turn the key on....do not start....pump the gas pedal 3 times within 5 seconds.....then turn the key off and back on and it should be reset....sometimes u have to do it a couple times.......and what heater fan r u talking about?.....
THE 1ST THING U DO IS GO UNDER THE HOOD WHEN ENGINE IS HOT, CHECK THAT BOTH HEATER HOSES (INLET AND OUTLET) ARE GETTING HOT, IF ONLY ONE IS HOT FLUSH THE CORE, IF BOTH ARE JUST WARM THEN THE THERMOSTAT IS DEFECTIVE IN THE ENGINE, REPLACE IT, LET ME KLNOW WHAT YOU FIND.
You will have to remove the serpintine belt off take off the Hoses from the steering box be carefull not to strip them out, use some WD-40 or something the make it easier if they wont come off take your time and work them back and forth, If your just doing the pump then take the hoses off the pump not the steering box, take the retaining bold out of the steering pump and it should come right off.
