I have this 06 passat 2.0 turbo. I changed the head cylinder and I remove the oil pan and install a new oil pump, after I put everything back together I started the car and it run for about 30 seconds but then it shuted down and I cant make it start again. It just cranks and sputs like wanting to start but it does not. So far I checked for spark and all 4 coils spaks good, the timing belt is aligned as it has to be. I got a code p0190 which is for the fuel rail sensor. Could this little sensor makes the car not to start? Any advise is appreciated. Thank you

If you do not get any help on this forum, Might I suggest that you Google "VW Forums"
There are several to choose from with a wealth of information.

First thing, Check all your wires again... forget any? Plug any in the wrong place? (which in some cars you can do easily)

When it started I had to pump it several times and after a various tries it started but 20 to 30 second later it shuted off. When I was checking I found a plug disconnected for the throttle sensor so I connected in but since then it does not start. I deleted the codes and none came back again but the one for the fuel rail pressure sensor. P0190.

It appears you know quite a lot about cars. Like I say, go to a VW Forum and you will get more help than you think. Have been on the TDI VW forum when I had a Diesel and those guys know VW's. This site is more legal, social, and homey with a very small touch of technical.

. Check/replace the MAP Sensor, after checking hoses and connections. This sensor may be at the heart of your problem. There's a very sensitive crystal resistor inside that is affected by changes in manifold pressures. It affects timing and fuel injection.

. Check the fuel pressure on the fuel rail, using a gauge.

. Remove the spark plugs and check each cylinder's compression.

Was the head replaced, due to the engine overheating?

I have a fuel pression of 55psi. The compression test gave me 180 on cylinder 1, 160 on #2, 180 on #3, and 160 on #4. I installed a new head with new chain and new tensioner, new timing belt new spark plugs, and a new camshaft possition sensor. I am getting the p0190 code. I checked for spark and for ground with the omhmeter and with a light tester. I got 12.9 in on pin 1 of the coil connection, good ground on pin 2, 0.3 of an amp on pin 3 and good ground on pin 4. I can see the sparks on all coils if I turn the light off and crank it. Any other things to check?

If you have a Fuel Rail Pressure Sensor, check the connection and sensor. These can be problematic on VWs.

I rechecked the ignition coils and three of the four seem to be bad I turned the lights off and I asked some one to crank the car and I saw only one coil sparking so I moved it from connection to connection to see if it still sparks in the other connections and it did it then I checked the coils using my ohm meter and got some results that I don't know how to interpretate if some of you know the right way to check the coils I will appreciate if you share it with me. My frp sensor is good and the connection as well. Thanks tx

There's no good way to confidently check coils, since you cannot duplicate conditions under load. Use your best judgment and replace, if necessary.
