yogi11 Posted November 23, 2014 Share Posted November 23, 2014 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? Quote Link to comment Share on other sites More sharing options...
8.1HD/ALLISON Posted November 23, 2014 Share Posted November 23, 2014 Possibly. Try turning the key to the run position but dont crank. Wait a few seconds to let fuel pump run and reprime system. Do this a couple times and then crank. If it starts better im guessing you have a fuel system thats loosing prime. Shouldnt have to crank that long. Either way take it in, that what warranty is for.

yogi11 Posted November 23, 2014 Author Share Posted November 23, 2014 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.

blackout07 Posted November 23, 2014 Share Posted November 23, 2014 We don't have that issue, but the coldest it's been in SE TX is mid to high 30s. Quote Link to comment Share on other sites More sharing options...

You can still leave it in the run position by not putting your foot on the brake and pushing the button twice I think. That could show if the low pressure pump is leaking down anyhow. The HPFP is engine driven though, not sure how to test that. Quote Link to comment Share on other sites More sharing options...
The Zip Posted November 23, 2014 Share Posted November 23, 2014 yogi11 - I started a thread "....Engine Cranking But No Start", in which GM addressed this by issuing Service Bulletin 367758. This may not be your issue but check it out. Also, you may have found out if our OEM batteries have enough Cold Cranking Amps (CCAs). Car batteries need enough CCAs to turn over larger engines when the temps dip pretty low, as the temps warm it's easier for a battery with insufficient CCAs to crank the vehicle. Do the research and find out what are the battery CCAs for this vehicle and compare it to the OEM battery CCA installed in our trucks. I have been driving the Tahoe for 15 years and in both previous versions I had to install a bigger battery, CCAs were way off the mark. If you confirm this and the dealer doesn't do anything about, a top of the line battery with correct CCAs will cost you around 125 bucks.

yogi11 Posted November 26, 2014 Author Share Posted November 26, 2014 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. Quote Link to comment Share on other sites More sharing options...

They don't even have to pull the engine fan belt, nothing. Its right on the front of the engine. Don't get your hopes down on your truck! Plenty of warranty, GM has been VERY vigilant in watching for issues on these new engines. Quote Link to comment Share on other sites More sharing options...

310racing Posted November 27, 2014 Share Posted November 27, 2014 Unleaded or E-85? E-85 takes significantly longer to crank when cold in these trucks/motors. Quote Link to comment Share on other sites More sharing options...
yogi11 Posted November 27, 2014 Author Share Posted November 27, 2014 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.

fondupot Posted November 30, 2014 Share Posted November 30, 2014 the longer crank times are because of the direct injection. its normal. Quote Link to comment Share on other sites More sharing options...
