gas pump fuel engine starter start gmc
Sent to Car Experts September 11 03:41 PM

When my 1997 GMC Yukon sits overnight, it won't start in the am. If I spray starter fluid (which I realize is not good for the engine) into the carborator, it starts right up and is good for the day. If the vehicle sits for more than 7 or 8 hours, I have to go through the entire process again, as it won't start any other way.The fuel pump was changed about 6 months ago, with no problem (other than not an accurate reading on gas level) since then.Anything you can suggest would be greatly appreciated, as I'm in outside sales and without a vehicle, I'm out of work. Thanks.

You will need to use a fuel pressure gauge before starting it in the morning to determine just what the fuel pressure is doing. Some of those engines require some pretty high pressure and get touchy if it's not right.

Reply to Hammer Time's Post: The fuel pressure has been checked by a mechanic both in the am and mid day and it checked out fine both times. I've had 2 mechanics that have looked at my vehicle and both thought they had the problem solved - but didn't. Let me know if you have any other questions.
