found the problem , it was the fuel pump it had about 15lbs of pressure changed it runs fine happy happy happy

Just curious is 15 psi too much or too little?

15 psi is roughly one atmosphere; a fuel-injected engine likely needs more. But then, I'm a computer programmer....

you're mixing standards, references and absolutes.

WAY to low. The pump should be putting out around 55-60 psi on that truck.

Thanks. Doubt I'll ever use the info but nice to know.
