As the title says, my newly purchased used Tregg(60k miles V8 ) is having a hard time starting. It turns over but it takes like 15 seconds for the engine actually start running. If I turn the key back and try again, it starts fine. Only misfire codes. The truck is at a reputable local independent shop. Reading other threads I suspected it was crankshaft position sensor, but the engine runs fine once started up. It makes no difference if the tank is empty or full. Could it be the fuel pump?

The camshaft position sensor did not fix the issue:-( Does anyone have suggestions? I did search the forum and the only two fixes I found were the cps or the n80 valve...

Is this how your mechanic communicates with you?

If so, that's pretty cool!

Update, the dealership determined that the fuel pump is bad. They won't have a replacement part until next week. That video was spot on :)

Gee, I wonder which VW dealership this is???
According to the youtube account info, it is Escondido German Auto. Must be an indy repair shop.

Or was that sarcasm VWDude?

The dealership replaced the fuel pump, the issue remained. It ended up being the checkvalve in the second fuel pump. The total bill came to $1150.....Minus my $200 deductable the extended warrranty (National) picked up the bill :cool: I have two new fuel pumps and a crankshaft position sensor, but the best part is that my Touareg is fixed and running right finally....

Old thread I know, but just curious...was the check valve inside the fuel pump? Or was it a separate part from the fuel pump? Any idea on how difficult it is to replace? Thanks

Probably means the pressure regulator valve assembly that sits above the pump right below the access panel. Pretty certain there is no check valve in the fuel pump. The pump is nothing but a submersible suction pump if you take it out of the casing and view.
