Okay guys im brand new to this and i am definitely having troubles...

I have 2001 ford f150 v6 4.2L
Im misfiring on cylinders 2 3 4 and 5

I replaced the ignition coil, spark plug wires, and put in motocraft spark plugs no change

I have a new fuel pump and new fuel filter, and i put in fuel injector cleaner... nada

I hoping i dont have a valve springs on each side that had straight-up snapped.. but in that case wouldnt all the cylinders not work???

This is out of my knowledge range

But i did notice on the ignition coil wire spot 3 was fried which is right next to the module sense that connects to the ignition coil.. can this be the culprit???

Really need some advice right now guys

 

A compression test may be in order. This test will determine if the problem is mechanical.

 

Are you sure you got the wire order on the coil correct?

 

What is the easiest way to do a compression test??

 

Yes ignition coil is 1 2 3
5 6 4

To the plugs. 1 2 3
4 5 6

 

1. Get a helper.
2. Get a compression gauge that screws into the plug holes, parts stores should have them in their loaner kits.
3. Pull the spark plugs.
4. Pull the fuel pump fuse or relay.
5. Screw the gauge in, have the helper floor the gas pedal and crank the engine over for 5 seconds, take the reading.
6. Repeat for the other 5 cylinders.

Compare the readings for consistency. Any more than 15% tolerance can be a problem.
