no spark
hello, I own a f150 98 4.6 auto no mods, my truck will turn over and no spark every morning I got power to both coils and no ground pulses. after a minute or two of cranking the engine starts replaced the camshaft sensor, gas, air filter , new motorcraft plugs and wires, cleaned the maf sensor and iac valve with no avail no CEL codes 40psi fuel pressure, could the PCM be bad? once my truck starts I can shut it off and turn it back on all day and runs fine till the next morning
