Hi. Have read other related posts and tried the advice but cannot get the engine to start. Appreciate everyone's posts and would really appreciate some advice.

Engine stopped midway through a 200 mi trip. Would start rarely but a few times started when warm but only ran a few minutes. Towed home and now no start and no smoke. Am a weekend mechanic. More of a electronics guy and have the tools and experience to repair circuit boards.

  • Engine cranks over.
  • HPOP has oil within 1" of top. No HPOP leaks.
  • Fuel pump runs and fills fuel filter bowl.
  • Fuel filter is new. Changed filter when checking to see bowl fill by pump.
  • Batteries are charged and less than 1 yr old
  • GPR test good
  • Tach does not move when cranking. WTS DOES light every time.
  • CPS was replaced by Ford on recall 6 months ago.

Do not have a high end code reader but have a dashcommand which provides limited but some information. The data it provides is in the context of the PIDs interpreted by a set of dashes I am using. The interpretation of the pids was done by user rallyclimber at iPhone and Dashcommand with my 02 7.3 - Ford Truck Enthusiasts Forums.

When cranking the dash command provides these measurements:
  • EOT=59F
  • IAT=56F
  • IMAT=106F
  • EBP=14PSI
  • TFT=57F
  • ICP=2000PSI while cranking and 222PSI with key in ignition after cranking stops.
  • GPR=98.83 (not sure what this number represents but the GP side of the GPR terminal reads ~.75 volts less than the hot side of the GPR.
  • MAP=99 kPa

Check engine light does not come on and the dash command does not read any codes even though it has a limited capability. All fuses test OK.

Appreciate any suggestions on where to look next.

It's either dashcommand or scan gauge pro that has the injector buzz test. Try that too.

I have it on my samsung tablet. Works great.
