My truck will start but will die when I run up the rpm popped code for low fuel pump relay voltage, changed relay still same problem I have spark but no fuel out of the injectors changed the fuel filter no luck jest got the truck trans rebuild about 2 weeks ago been fine til it had random rpm jumps around 70 mph the when I can to a stop the truck died but started right back up died again right after I stopped again about a quarter mile later. when the truck cools down it'll start back up but dies when I run up the rpms. fuses are good and I always have spark no fuel from the injectors. sorry if I'm repetitive. truck idels fine when it starts just when I run up the rpm does it die. I have good fuel pressure from the pump up to the TBI tried switching the injector plugs and it started but did the same thing under higher rpm. Any idea
