When you crank the motor, does the tach move any? if it moves, it is not the CPS. If it does not move, Probability says CPS. post more after you test this to see.

Check the fuel pressure. Schrader valve Looks like air valve) on the side of the FPR on the fuel filter.

If the tach is moving it's probably not the CPS, but can't rule it out.

Cuda_jim... Turned The Schrader Valve..fuel Came Out.. Tried To Start The Truck And No Luck. Opened The Fuel Filter And There Is No Fuel In The "whatever Its Called". We Have About The Same Amount Of Gas In Both Thanks I Think... So When I Tried To Switch Fuel Tanks The Gas Gauge Didnt Move. Changed The Cps And This Didnt Change A Thing. Truck Still Has No Fire. Fuel Filter Was Changed Two Weeks Ago When It Left Me On The Side Of The Road The First Time. Any More Suggestions?

fill the fuel bowl and see if it will start if it does see how long it will run then if it dies again check the fuel bowl most likely it will be low on fuel again sounds like you need a fuel pump
