I have a 02 Nissan Altma that is hard to start, First start of the day it will crank and crank for what seems like 10-15 sec. then it will run very rough, like its only hitting on 3 cyls and its 5-600 rpm slower than normal. It takes about3-10 sec. to run normal. The car runs great when Iam driving . After that the rest of the starts are not as hard, But up till a couple of weeks ago All I had to do was touch the key and it fired right up.The car has 95000 mi on it. Thank you for any help.
The next first start of the day try this. Turn the ignition to the run position so that the dash lights come on for two seconds and then turn the ignition off. Repeat this a half a dozen times and then try starting the engine. If the engine starts with no problem, it means the fuel pump check valve is faulty.
