Sounds like the crankshaft position sensor to me.

Ok so update on the situation. Car still doesn't run. I have replaced the IAC valve, the TPS, and cleaned the MAF sensor and the throttle body. I have swapped out the coil packs and the ICM. I have installed a new fuel pump, fuel filter, and fuel pressure regulator, and I also changed the crankshaft ...

And the fuse is not blown

yes, i can hear the fuel pump prime when i turn the key to on. i bought a new fuel pressure regulator and am now getting 10psi. seems low

Is there a test for the fuel pump control module? Or a way to tell if it specifically is what is wrong with the car?

PS - Got gas?
Sounds stupid but it's easy to do..

Yeah - you almost hate to ask but it happens. It's also possible that the gas gauge is getting flakey & showing more gas than is actually in the tank. If there's any doubt add a couple gallons & make sure.

I thought the same thing. When I had ...

The fuel pump is brand new. Replaced it this past weekend. Fuel comes out of the rail telling me there is pressure there.

It doesn't register fuel pressure when I crank it.

Just picked up a fuel pressure gauge. Will check when I get off work.

No difference with the MAF plugged in or not plugged in.

INstalled a new filter and pump. Starts like normal, but dies instantly, even when I give it gas it revs a little but dies anyway..

Spoke with my mechanic, he got it running on throttle body cleaner, so since it runs on that we're thinking it's a fuel problem. Going to change out the fuel filter and check the local scrap yard for a pump.

Stalling is the least of my problems right now. It wont start now and just sits there and cranks.

I can't find any vacuum leaks, I will check again however. Is this something that would throw a code. I don't seem eot get getting any codes from the CEL.

I will do that this weekend. Is this something that would also cause me not to get full boost? Even under heavy acceleration It barely goes over the zero mark?

Took the ICM off, got one from the scrap yard, took them both to autozone and had them tested, both tested good. I'm guessing this eliminates the ICM from it, planning on changing the CPS this weekend unless anyone has any better ideas?

This sounds just like the same symptoms I experienced on both of my Bonneville when the ICM went. I have heard that advance auto/autozone can test the ICM but I may be wrong. (I may be wrong on their ability to test them.) I would always just swap parts between my to Bonnevilles to locate the ...

It could be either one. There have been more reported CPS problems, than ICMs. Does it start right back up? Have anyone that you can swap ICMs with?

It starts right back up, but it takes it a few seconds of cranking to fire. I've replaced the CPS before, and remember having to come to a stop in ...

Ok guys, here goes. 2000 ssei is stalling randomly. Sometimes it stalls while driving 3 mph, sometimes at startup, sometimes while im driving 60 down the interstate.... I have replaced the throttle position sensor (threw the code for it), I have replaced the air idle control valve, and cleaned the ...

Yes with aftermarket. Plan to replace it with hockey pucks this weekend. Will see if that fixes it. Thanks.
