Won’t start

wtroger · 2020-06-29 03:17:02

Taken from the Oregon Fuel Injection site... RPM, minimum 100 rpm cranking speed (When warm it should be over 180 rpm) ICP, minimum required for starting 500 PSI if no rpm signal, ICP won’t go over 400 PSI Voltage during cranking 7-10 volts minimum depending on year Pulse Width; 0 ms means no sync, 1994-1997 .42 ms indicates that PCM and IDM are in sync (on 99-03 it should be .60 ms) and the PCM is waiting on the ICP to reach the minimum of 500 PSI. When min. ICP is reached PW should change to 1-6 ms If any of the above doesn’t meet the minimum specification, solve the problem as-per the appropriate Ford Diagnostic Manual.

You still have pretty low cranking RPMs. Do you know what your cranking voltage is?

Great news!

Just for comparison sake, monitor the same PIDs as in the image above and see what they are. This will give you a baseline of what your truck is looking for and probably show the RPM up near 200.

Let us know what you find if you do this.
