Hi, I have a 2000 ford 5.4 Triton and I have no spark on #5 cylinder I swapped Coils with #1 and both coils work on #1 but neither will work on #5. All other cylinders spark and run fine. Can anyone Help?, thanks

It can only be two things to cause a no-fire at coil #5. Either the light green/yellow wire for coil #5 has an open short in it, or the engine management computer is defective.

It’s located on the right side of the engine compartment.

Before you go buying a new ECM, check the coil connector and wiring VERY carefully. Have you changed the #5 PLUG??
