Truck when starting cold or warm just cranks, seems as though has no fire but if you pour gasoline into throttle body it will start and run just fine, I have replaced tps sensor and fuel filter and still starts real slow, cant get into shop for 2 weeks around here and cant afford to throw parts at it can you help?Oh yeah forgot, the fuel pump is working fine, you can hear it running and it makes a lot of gas when we changed filter it shot out good when turn on key.

Do you have the spider fuel system on this vehicle? If so that system is noted for problems. Start-up fuel pressure can be critical, usually around 60--66 psi. One it is running, it will run with less pressure. I haven't looked up info on your fuel system, yet.
