Hard start & stalling problem - when car is warm? - Page 2

Sounds like some fuel pump problem

lol.
I keep gas in my car, so that's definitely not it.

I think the pump itself is in good shape.
I was thinking maybe fuel pressure regulator...

CPS and Serpentine belt arrived today. Figured if I have to take the fan off, I'll put in a new serp belt too. Who knows when it was done last!

2 CPS sensors and serp belt installed. Wow, what a ***** to find the connector for that intake CPS! It's frigging UNDER EVERYTHING!
Cleared my CEL, gotta go drive it around a bit now and keep my fingers crossed. Should take about 5 minutes before the sucker comes back on

On the bright side, throttle response is back to normal, nice snappy bmw feel.

50-60 miles on the car since the VANOS repair and the CPS replacement. Still no CEL, although the car did refuse to start today - sits there and cranks like it's still not getting fuel, and then starts.
However, it *didn't* act limp the hard-start, like it usually does.
I'll check for codes in a little bit, even though the CEL is still off.

Any other thoughts?

Scanned codes with the peake tool: 15/41: Camshaft Position Intake Sensor
WTF. Returning the aftermarket and purchasing the $116 OEM one today I guess.

OEM sensor installed. Cleared CEL again, time to go drive...

Try to reflash the DME, I mean you've replaced pretty much everything on that car ....

I don't beleive hard/hesitant starts have anything to do with the DME, but some of the problems you've mentioned- car stalling when slowing down/breaking to low speed- could be fixed with a reflash. Not sure if you did, but check the spark plugs, take'em out and examine them.

Engine is now throwing codes for the EXHAUST camshaft sensor! Stupid aftermarket sensors!
I'll have to order a new one and put it in Tuesday.
On the bright side, the car is running fine otherwise.

Carthage - I'll search the forum and look at reflashing the DME. I'm not sure what that means but I am sure I can figure it out with a search

So I put my old sensor back in, no engine light and no Exhaust Camshaft Sensor code.

NEW code: "EVAP LDP reed switch doesn't open".

How'd that happen? Could the old exhaust CPS be bad and cause that code somehow?
