Fuel pump hums (primes) when turned over. When “crank no start occurs”, jump start with or without charge starts vehicle. Where do I start?


RESPONSE

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.
