I can't begin to decode what thats supposed to elude to. PM me if you don't wanna post it plain text.

There is no reason for his external switch. Just putting the fuel pump on a relay of of the ign switch does the exact same thing (and its how you'd run an electric pump on an older vehicle).

If its dying or not catching, there is something else going on. A vehicle that has frequent failed starts should be tossing a code, possibly a misfire hit, knock, MAF code, crank or cam sensor failure etc. If there isn't a mechanical cause, then either the ase is wrong, or something else was changed in the tune thats causing an underlying problem.

There's more going on here than we know. Was he using the truck normally before he decided to wire in this switch?
