Hey guys, I've got a 2006 f150, 5.4 v8, I was having problems with the truck, I forget what code came up on the edge. But after some research I came to the conclusion that it was possibly the module, went ahead and replaced it today and now the truck won't start. My headlights flash on and off when I try to start it, and the edge flashes, but the truck won't turnover.

Any ideas?

 

Did it start before the swap? If so I'ld swap back and check.

 

Yep the truck did start Before the replacement, I tried the "old" one back and I had the same result. I did notice the instrument cluster gauges were almost vibrating back and forth quite fast as u removed the key from the ignition.

 

Check your battery

 

Yep. Battery

 

Sounds like when my '07's group 59 battery died suddenly last year, swapped in new Kirkland Group 65 .....

 

The fact that it won't turn over tells me that its not the FPDM...

If there was a problem with the FPDM then it would crank but not get any gas so it would never fire. (right?)

 

check the battery....

 

Replaced the battery and she fired right up. Everything seems to be in working condition.

Appreciate the help guys.

 

good....glad ya got it fixed....
