Friend's 2004 Focus ... dash lights would go dim, car quit, and check engine light indicated a fuel pump relay issue. Owner was advised to buy new battery. Car quit again; battery replaced under warranty. Car quit, battery replaced under warranty. (unbelievable, eh?). Took to Ford and received a $1,200 estimate for replacing fuel pump and relay. I found high resistance where multiple wires are attached to battery. We cleaned/soldered wires on both negative and positive terminals and problem has not returned.

Very good!

Tx for posting that, you found the "simple" real problem there.

One should always suspect battery power issues when several oddball electrical issues pop up out of the blue on these. Fuel pump acting goofy is one of them.

Yay, someone who didn't throw a part at it just because "the scanner said so"!

Admit it, amc49, that brought a bit of a tear to your eye...

Well, they WERE chasing the correct issue but should have re-loadtested new battery to realize something else was causing power supply issues. More than one thing can do that. I got tricked by same issue once in my early Focus days but realized not fuel pump when other electrical things started acting up too. The fuel pump shows pretty quick with slow operation like something is wrong with it.

Admit it, the OP did well.

Others were replacing the battery/estimating other problems before he found the real issue.

Should've changed all 6 trans solenoids for proper fix. MTX or ATX, change em'. He'll be back.

What's an MTX? I can barely handle the 2 pedals I have now.

All in fun, it was refreshing to see another "how I fixed it" instead of a how to question.

As Leora noted, one that didn't blindly follow a "code".
