Q: Can't start, hot relays

asked by on

About two months ago, my vehicle wouldn't start. Or it might start, but then run a while and die. Three different mechanics told me it would be the fuel pump, but I couldn't afford to replace it at the time, so I decided to wait. One of my friends took a look, though, and noticed the fuel pump relay was hot, and replaced it for me. For two months since, my car has started just fine. Recently, though, the problem started again. I replaced the relay, and that did the trick again for the time being. Would a bad fuel pump cause my relay to run hot? Is it a reasonable bet that if I replace the fuel pump, I won't be wasting money?
