Hi everyone
Was wondering if anyone out there has any suggetions as to what happened. Here is the run down; lately my truck has been acting funny

sometimes it starts on the first turn and sometimes all it does is just cranks

. But when it does start is runs great, I just had the motor rebuilt a few months ago. The only things that have not been replaced is the battery, alternator, and a couple of solenoids. But other than that everything was working fine. I just replaced the fuel pump yesterday, thought it wasn't getting any fuel. I fired up my truck on the first turn was running great then my radio got fuzzy and as soon as I put it into reverse she died, I mean she died

no power, no nothing! Doesn't even click when you turn the key, no headlights nothing works.

If anyone out there has any suggestions as to what might be going on please help, I miss my girl already!
Thanks
Nick
