did the cam sync replacement on my 96 explorer awd 5.0 l had the tool droped the sync got it bact to where the last one was. followed the procedure pretty close I did forget to remove the battery cable. so here is the issue I now have 0 fuel to the rail. is there something I might have messed up or left unplugged that would cause this. anyone had this problem did my fuel pump poop out the same time my sync did any thoughts would be great im stumped as even where to start .

 

The cam synchronizer should only effect the injector pulse, not the fuel pump. You should confirm that you didn't inadvertently trip the fuel pump inertia switch, then check for voltage to and through the switch.

It wouldn't be unheard of more than one thing to fail. My friend called me over several months ago to help him diagnose his '96 Explorer Sport. His wife drove it home from work, parked it in the drive way, but it wouldn't start the next morning. I first checked for fuel pressure, it was fine. I then checked for spark and there was none. I used my oscilloscope to confirm there was no pulse from the crankshaft position sensor. The next day he went to the part store for a new CKP sensor, installed it, still no start. After he promised me that he had properly spaced it, I went back over. He had spark this time, but no fuel pressure. The next weekend he replaced the fuel pump and the truck started right up.
