It will turn over but want start, ive change the fuel filter and still nothing. When i turn key over i do hear a clicking sound from under the hood. Not sure what it is thats clicking though. Any help would be apreciated.

 

Could be several causes.
Battery, corroded cable terminals, start solenoid.
You have to begin to eliminate these one at a time to get to the cause.
What happens to the Theft light?
Is cranking at normal speed?
Do you hear the fuel pump run at key on for a couple seconds?
Every body dives for the fuel filter.
It won't be a cause for a 'sudden' no start.
What is the fuel pressure with a gage on the fuel rail?
Test by cycling the key to run several times.
Good luck.

 

so the motor is not turning over ? You hear a "click" under the hood ? Solenoid trying to pull in.. Is the battery at full charge ?
---if the motor is cranking, but will not start, is the "theft" light on center top of instrument panel ? Have you tried a second key?

 

It will turn over. Just want start. Battery not but about a year old. But if I do just turn the key over I hear a click click sound. I've never notice that sound before. Theft light come on when I turn the key but then goes off

 

have the same problem on my 97 f150 xl 4.2. dropped the tank and straight wired the pump and it runs. all the fuses and relays work. heard about the camshaft positioning senser. any other thughts or helpful

 

clicking may be the fuel pump relay working, do you hear the fuel pump prime itself?

 

Yea took pump out the tank an straight wired it to the battery

 

is the check engine light on?
does it have fuel at the rail?
does it have spark?

 

Haven't been able to work on it today rain all-day. Will just on it first thing in d morning. Will keep u updated
