I second the fuel pump relay theory.

By the way, why did your change the throttle body? and the sensor?

Good luck!

The pump supplies more fuel then the engine can use and the excess i
returned to the tank so there is no possibility there can be air in th
system. What about the fuel filter? Was it replaced along with the ne
pump? Thinking the new fuel pump replacement and your current proble
have nothing in common. Remember the engine also needs spark to run. Yo
need to determine if the no-run problem is because of no fuel or no spark.
Also the fuel pump has a relay in the circuit. There is a chance the pum
that was replaced was still good and the original problem was a bad fue
pomp relay

My old 0BW is starting to get expensive in its old age. In the last
three weeks it's had three separate major part replacements. First week,
I had a $1300 dinger for a new throttle body and sensor. Second week, my
battery conked out, but fortunately I went aftermarket for the
replacement and got it done for around $100. And now this week, all of a
sudden the fuel pump conks out, and now I got dinged for $800! Yeesh!

Anyways, I'm venting, nevermind. There is one effect that I'm seeing
after the fuel pump replacement. I'm finding that the car no longer
starts reliably. Later in the same day I got it fixed, I found out twice
where it no longer was getting fuel again. What would typically happen
is that I'll start it up, it'll work for a few seconds and then just
die. Then I'd try to restart it several times (maybe 5, 6, or 10 times)
and it will not ignite, and then randomly it will all of sudden work
again. Thank god for the brand new battery, it's trooping along
activating the starter for as many times I'm retrying. Now is this to be
expected from a new fuel pump? I mean will there be some air or moisture
in the lines after the pump replacement, and it just needs to work its
way out of the system? Also I noticed these problems occurred during a
major rain downpour, so I'm wondering if that was a coincidence or not.
It's been acting okay today, but its hot and sunny today. I got the pump
replaced on Friday, and the dealer's service centre is unfortunately
closed on the weekend, so I can't talk to them till Monday.
