I just re-read the whole thread. Let me stop for a moment and take an overview, and offer some professional advice.

First, what did you do in terms of following up on your codes?

Did you do the fuel pump volume test before declaring it "bad?"

Did you determine that you had a good spark when the car was failing to start?

I ask these questions because I discourage people from going down the road of parts replacement in place of good diagnostics. It's an added expense, and not a good as finding the root cause and making a workmanlike repair.

Before replacing anything else (outside of a known needed maintenance item, like a fuel filter that's due for replacement) make sure that it is a causal factor and not just a good guess.

The car only has 93 k and when I first got the car 2 years and 70k ago I changed the fuel filter and tuned it up. Ill just keep driving it and run it low on fuel. And keep checking the noise which is getting louded. I cant imagine the fuel pump making this loud and this type of noise. Thanks

I that case, the logical next step is to have another tech or similar person listen to the noise.

Definitely isolate the sound further. Get under the car while it's running, and see if the sending unit is actually the source of the sound. There's not that much else around that area to cause a loud noise, but you never know...

And props to timebuilder for excellent and thoughtful advice. I wish I had had a mentor when I was first learning 15 years ago, it would have saved me a lot of heartache (I went down the "replace a part then see if it was the problem" route more than a few times back then).

As for the longer crank times when starting, remember that the fuel lines are under pressure. When you replaced the pump, something may have cracked or unseated itself. It almost sounds like gas is draining back into the tank (a problem I had with my carb'd 88 Corolla and 87 Tercel wagon).

You're welcome. My mentor was Popular Mechanics, Hot Rod, Car and Driver, and Rod and Custom. Later, it was Big Bike and Chopper magazines.

If you have a long crank time, try this. Turn the key to ON a couple of times, then go for the start. If it catches right away after that little procedure, you are having a delay in starting while fuel pressure builds up, and you may not be holding line pressure. Most in-tank units have a check valve built in to keep fuel from bleeding out of the pressurized line and draining back into the tank. Sometimes, the fuel pressure regulator keeps pressure from building to full spec. Give it a try.

Oh, and the "replace parts until it's fixed" method is costly and frustrating. You wouldn't believe how many beginning techs use that method.

"Test, don't guess."

Update

Havent had the starting problem since I replaced it. The noise is coming from the tank. More crappy news, today it would start but wouldnt idle. If I pressed the gas down I could keep it running. It only did that one time. Then I get home and notice coolant dripping down from the passenger side engine. Looks like a water pump. Looks like a pain in the butt to replace.:ugh3:

do water pump and timing belt, all Toyota parts pefer. u wont have to go there again for next 100k miles.
