The truck would start and drive and and then just die. I had the fuel vacuum leak fixed, didn't fix it. They replaced the fuel pump twice. I got it home and tried to start and lagged and then started . The oil gage started going back and forth the was not idling we. I could here a ticking sound it the dash . What is going on?

check your oil pressure with amanual guage then check sending unit on oil.if it's bad truck won't run as it shuts off fuel. also check to see if that has been updated fuel pump as the harness near the tank has to be replaced.
