Starts but won't run
#2
Two possible problems come to mind with that truck, fuel or spark. The high psi pump can go bad and only get enough fuel from the primmer pump to start but not keep running. The only way to check this is with a fuel press guage. Just feeling or listning is not a true test of a part.
The other problem I used to see with those was the ignition modual on the side of the dist. They usualy wouldent start but sometimes I have had them do this too. The best way to test loss of spark would be to pull one plug wire and put a spark light and then back to the plug. That way it doesnt gas wash the cyl. Have someone start the truck and moniter the light and the fuel press guage. One of the two should tell you where too look.
