Intermittent Crank 2002 Ford Explorer

2002 Ford Explorer Sport TracI have a 2002 Ford Explorer Sport Trac with an intermittent crank no start in varying outside temps. Alternator volts @14.2. Battery live. Fuel pump hums (primes) when turned over. When “crank no start occurs”, jump start with or without charge starts vehicle. Where do I start?


Intermittent Crank No Start

Replace the battery. Most likely the battery has an internal short. The battery has enough juice to crank a little but not enough to do the job proper. This is why it doesn’t take much to jump start it.


Removal and Installation
    1. Disconnect the battery cables. For additional information, refer to Battery Disconnect in this section.
    2. Remove the battery heat shield.
