My truck has been acting up pretty bad here lately......its hard to start it.....the only way i can get it to start is to lower the FP below what it is suppose to be stock......here are my list of mods

50 lbs inj.
vortec heads
comp cams cam( .500 and .510 lift)
bored out .030
255 fuel pump
atr underdrive crank pulley
pte52 and 3 in. DP
hartman TC
ngk ur5 plugs(.35 gap)
atr black bueaty plug wires
and some other stuff but it has nothing to do with the motor or computer

my stock motor had the same problem about 3 months before i desided to rebuild it......if anyone one else has had this problem please let me know what u did to fix it.....its starting to get a little anoying when u cant start ur truck at the gas station and have to pop the hood everytime...

thanx in advance

Well,

The 50# injectors are sposed to be set at less FP than the stockers. 40# comes to mind - although I'm not real sure as I'm running stockers.

If it starts with lower fuel pressure - why bump it back up?

What are you doing underhood to make it start?

Most of the hard start issues I have seen are fuel related (read clogged fuel filter)

Is it turning and not firing - or are you getting starter click?

you might want to let us know what you are using for to fuel tables?

the appropriate answers are: ( yes this is multiple choice, so pick the one closest to what you think is what you have)

dfi?
fast?
custom chip designed for 50# injectors?
Chip designed for stock injectors? <----hopefully this is it cuz then the fix is easy
