Here is a recap of a previous closed message: Ford F150 won't start May
25 2006 Truck was driving fine when muffler exploded and truck did not start again Engine Crank There is fuel There is spark There is a new ignition module New distributor cap New Rotor I did check the firing order and if the wires were in the right order : 1 4 2 6 3 5 just as required with wire number one at the right locationThe only thing suggested was the timing gear must be damaged. That's where I was a month ago I just took the cover of the timing gear and they appear perfectly fine with a TDC both marks on the gears whre they should be. So now I am doubting at all that the gear are the problems.
There is however a timing problem. If I rotate my distributor one notch at a time , I end up being able to fire start the engine. But unless I rotate slowly by hand the distributor as the egine runs it dies. I keep doing the same thing other and other and it start. Eentually my distributor had been rotated 360 degrees. I was not able to figure out why the timing keeps changing.
