you have to drop the oil pan to get to it...once the oil pan is off there are 2 bolts that holdthe pump in place,,,you will also need a new screen for the new pump.

Sounds like it could be a mis-fire. At an idle, remove a plug wire to see if it stalls. If it does, re-install it and go to the next one. If you remove one and get no change, that cylinder is the problem. Test for spark.

You may have a bad or weak fuel pump, Try spraying Carb cleaner down the throttle body and see if the engine starts, if it does. You could have a dirty fuel filter that will need to be replaced, or a faulty Fuel pump "sending unit" Before you go off replacing the fuel pump, check all the fuses in the fuse panel at the end of the dash, drivers side. The check the ground wire to the fuel pump on the frame, a bad ground will cause a weak fuel pump. Then check your fuel pressure at the shredder valve, you should have 62-65 PSI with the fuel pump energized "engine not running", anything less then 62PSI the injectors will not work. If your fuel system is running 100% and there is 62PSI at the shredder valve, move on to checking the ICM "Ignition Control Module"/ When the ICM goes bad you'll not get any power to the spark plugs and check also the connection to the coil to make sure it's working also. Good luck and keep me posted.
