7-10 seconds cranking time is not normal and replacing the bad fuel injector fixed the problem. Now the Tahoe starts in about 2 seconds like it should.

Hopefully this is my last update: The dealers next try was to put in a high pressure fuel pump that is located under the intake manifold. After they pulled the manifold they found that #4 fuel injector was leaking so they replaced that. I picked up the vehicle yesterday and now we will see if this fixed the problem. This vehicle was sitting at two different dealers for a total of 20 days while they kept guessing and throwing parts at it. I do understand that you can get a new vehicle and have a problem which I accept. But when you bring it to a dealer you expect an accurate diagnosis and a timely repair which I did not get.

Another update: The dealer put in the new fuel pump and that did not fix the problem. They are going to call GM for help on what to do next. So far this vehicle has been sitting at dealers for 17 days now while they try and fix it.

New update: The new dealer told me they got the same scanned code as before and that they think it is a bad fuel pump which they have ordered. Now its parked at the dealer waiting for parts again. So far this vehicle with only 1100 miles on it has been sitting at a dealer waiting to get fixed for more than 13 days.

Here is another update on my problem. The scanned code on the Tahoe was "P00C6" which is fuel rail pressure to low. The dealer had my vehicle for 10 days to replace the camshaft position actuator solenoid valve and then called me to say it was fixed. The following day after getting it home the Tahoe is having a hard time starting just like before and it was that way for the next three days and then I get the service engine alarm on my dash again. I'm now taking it to a different dealer to see if they can fix this problem.

I use shell unleaded gas in this vehicle. Newdude post that it is very easy to change this part, but the dealer tells me that they have to pull the oil pan and the front cover of the engine to get at this part.

I just wanted to give an update to my problem. Over the past weekend I got an alarm on my dash showing the service engine alarm. I toke it to another dealer in my area and they tell me that the "camshaft position actuator solenoid valve" is the problem with it stating hard and also getting the engine alarm. They tell me that they won't have the part until next week and that it is a full day's job to put it in. I'm not very happy with them having to tear into the engine to replace this part. I didn't expect this kind of problem with only 1085 miles on this vehicle. Needless to say I'm not very happy with this vehicle.

This Tahoe has a push button start and I did talk to my dealer and they said it is normal for this engine to crank a while before it starts. I don't think it should take this long to start and I get the feeling its going to leave me stranded some day because it won't start.

I was wondering if anyone else is having this problem. When I start the Tahoe after sitting overnight the engine cranks for about 7 to 10 seconds before it starts. After the engine is warm it start within a second or two. Is there a problem with the fuel system?
