yup...

have the dealer run a electric current check on the pump. it's free if you still have the warranty. around $600 if you don't. check one of the threads on this. someone said the Ford Lightning uses the same I/C pump which cost 1/2 the price at Ford dealership.

Could also be the fuel pump. I had to have mine replaced. When I floored it, it felt like a 4 cylinder engine.

when your fuel pump went out, did you get the check engine light come on? My I/C pump went out without the check engine light even came on.

No, the check engine light will not come on. There will not be enough fuel pressure at times, so you will have temporary acceleration problems (ie no power). Eventually, the fuel pump will stop working and you won't be able to get your car started. At least in my case.

You can get the pump on ebay for 80 bucks plus shipping. The swap will take a couple of hours, but is fairly straight forward.

I hope its easy. I am not that good of a mechanic. lol. But I was reading up on 1fasts idea of the lighting pump. My only concern is adding the new connectors or splicing into the old ones. Electrical things makes me nervous

Wait, so is this problem only related to the intercooler pump, or does the fuel pump need to be replaced too?

It's probably just one or the other, and probably the i/c pump.

Yo, I just got my C32 back from the dealer for the same problem, losing power at high speeds. They replaced my intercooler, b/c it was reading the intake air temperatures too high b/c the coolent pump wasn't working for the intercooler , or something. Anyways it was under warranty, and didn't cost me a dime. Now my car drives like a dream again

I had the same problem till yesterday it wouldn't start. I took to the shop they think is the fuel pump but they said that they have to run some test to make sure if that what it is.

WOW THE POWER IS BACK. What a difference. I change the intercooler pump out like everyone said and wow what a difference. I used the intructions that 1fast come up with and it takes no time to do. The only thing that took the longest was those damn mb clamps that they use for the hoses. I hate those things. But I took my old pump off replaced it with the ford one and bam kicking *** again. Thanks everyone for the responses and help...
