Here's my run down. I have a v6 Ford E 150. It only starts when it wants to. It does crank over. When it does run it spits and sputters at times. If I'm going normal speed around 55 and slow down too fast to make a turn it just dies. It will run for 2 or 3 days and then stop and not start back up then it could be a week to a month before it will start again. I'm not I'm not getting spark to my crankshaft positioning sensor or my coil. I recently changed the battery and it started right up. It ran for a couple days but will not start back upn. I tried unhooking the terminals and leaving them set in hooking the backup but that did not work. Have new plugs new wires new coil.I'm lost?
