installed new fuel pump. it runs fine now. A few days go by. It won't start.

I'm not sure which brand it is. I changed it because the old one quit working. It had been in there for years. It could've even been the original one. I don't know.

WHY on earth are YOU questioning a time-traveler???? They knew you where going to ask that! It's obvious they've done this before!

I just can't help myself!

I changed the pump last week. 3 days later, it wouldn't start.

are you getting power to the pump?how did you check?

Also, while you're looking around, check for ignition spark just for the hell of it!
