4.2 V6 P0353 Rough Idle/No Power
Hello all, first post after much searching & reading.
2006 F150 XL 4.2 V6 with 5sp manual - son bought about 6 months ago at about 107k miles
Truck died on highway while wife was limping it home running rough. Towed home, charged battery (needed it). Cranks but wont start. Checked fuses 9, 32, 33 - found 33 blown. Replaced, started up but runs very rough. Head to Adv to check codes, getting only a P0353. Checked for any loose connections, none found. Researched here, found a lot about Fuel Pump Control Module. Surprisingly, it was in very good shape compared to what I read about on forums. Very little corrosion, no swelling. Cleaned frame and module up and reinstalled. Bought new coil pack from AZ, installed and get good crank but no start. Checked every fuse in box, none blown. Put old coil back in and starts on first try, but still rough, same as before. Drive to Adv to check codes, still only P0353 (not even any other pending). Read more on here, everyone seems to suggest new plugs in this situation, so I went with the Motorcraft Platinum gapped to .053 on all 6 (old were Motorcraft Platinum also). Plug wires look good but I did not ohm them out. Starts right up but runs very rough still. Buy new coil pack from Adv, install and same as one from AZ, cranks but wont start. Did not see any damaged wires near what I think is the accumulator, but will check again tomorrow in daylight rather than flashlight. Have checked the emergency fuel switch frequently also. New fuel and air filters, > half tank gas all this time.
Feel pretty confident if I put the old coil pack back in it would go back to rough idle. Will likely do that tomorrow. Thinking of changing plug wires but trying not to just throw parts at it. Don't see that it is PCM, but I could be wrong. Not sure why neither new coil pack would start.
Thinking of
1 - Verify flow at fuel filter
2 - Ohm plug wires or just replace
3 - Replace fuel pump control module
I'm frustrated, looking for some guidance. Any suggestions will be appreciated.
