Question about 1988 Ford F 250
I was slowing down when it died then it wouldn`t start . I have change the following coil , pick-up coil, map sensor , rotor and cap and fuel filter and still nothing .
Fine, do you have spark all the way to the plugs? What is the fuel pressure must be AT LEAST 42 PSI as soon as you turn on the ignition
You didn't mention the ignition module
Check the engine cranking Vacuum it needs to be at least 2" cranking if not the catalytic converters can be so plugged the engine can't start YES IT IS VERY POSSIBLE HAPPENS ALL THE TIME
The other reason you may not have 2" of cranking vacuum would be a jumped timing chain also check the compression look for any low cylinders add some ennginen oil to those low cylinders and if they do not come way up right away you have valve problems.
