05 does not have a fuel filter on the frame

 

what motor?

how are the wires? i had an issue like this and the stock wires were shot. threw in some new ones and it was good to go.

 

04 and newer the filter is inside the tank module with the pump.

 

5.3l
Are you talking about the spark plug wires?

 

yes spark plug wires. i bent one of mine together like in half, and it was so drie rotted it cracked and broke.

 

They are pretty bad looking but didn't check but I will swap in new ones tm. God damn it I put in a new fuel pump for no damn reason!!

 

^^^ That's the way it goes. Have you had any belt slip issues? Could be belt slipping and laying down. You could really stand to have a wideband permanently installed. But I would make sure the basic stuff is good like guys have mentioned. Plugs / wires is a easy check. And plugs do wear out.

 

Switched the plugs and wires and the monster is alive!! Burned a wire though after it was finished lol it was laying on the header and I didn't know!!

 

So you are running a stock non flex fuel fuel pump, I would have upgraded to a 255lph while you were in there.

 

awesome, glad you found it.
