hey, i have here a bravada year 2000 v-6 and i just did the fuel filter. i drove the truck for 5 minutes and once i shut it down it turns but does not start. now the fuel pump was loud when i first diagnosed it and after i fixed it it was much quieter than before and the truck ran, started 2 times after repair. once i shut it off the third time it would not start. temp outside is 38 degrees and i was wondering if a line was cut there would be fuel everywhere at 66 psi but i found no liquid gas. but when i turned the key while truck would not start i could smell raw fuel. is there a fuel line that is strictly for fumes or am i chasing ghosts when it comes to that? also fuel pressure was good enough to make the fittings i installed to leak (had to fabricate a new section of fuel line) and after tightening those up it would not start. battery terminal is loose and could not get the hood back open to tighten it up latch broke. any and all simple fixes (no matter how stupid ) posted as i would like to diagnose my customers car ASAP please let me know and thank you in advance.
