Not sure if its the same on the regular 6g's..but there is a fuel pump manual diagnostic method. There should be a 2 wire plug on the fireway near the brake booster area. You get some wire and ground it to the ground terminal and listen if the fuel pump is turning on. I will post the picture from the service manual when I get home tonight. I would do this step first..this will determine of the fuel pump is working.Originally Posted by mikew
Did you make sure all electrical connections are secure and/or connected?
When was the last time you replaced your fuel filter?
Its possible your MPI fuel relay may of gone bad. Get a spare working one and replace it and see the results.
Your fuel pump relay may of gone bad too...on the GVR4's its located on in the truck right under the trunk lik striker latch area. Not sure if its the same on the regular 6g's.
