I'm going to checkout the fuel pump ground and the fuel pump itself and if that doesn't help I'm either gonna sell the truck or send it to the scrapyard, which will likely bring me more than I can sell it for.
Take a step back! That what I had to do on mine! autozone and checker have scanners you can use for free. In the manual you have they have the values you need. I have one myself before I pickup the shop manual off of ebay!!
So first you need to know is everything working correctly no trouble codes? don't assume! and don't just throw parts at it! My son's truck the egr worked but the port was all carboned up so it was not working! Remember the computer takes the info from the sensor and adjust the tbi!! Its a pain I know! The truck site is great for helping you through the process of getting your truck to run right!!
