Nissan Repair: Nissan stalling., nissan frontier, leaky injector


Question
Hi,
I have a Nissan Frontier V6 2000. The engine don't start after been running for about 30 minutes in a hot day. I have to wait around 10 minutes before start again. Once start, the engine works fine. Sometimes I go somewhere that engine runs for 30 minutes or more and when I stop the engine for few seconds; the engine will not start until cool down (about 10 minutes).
Any idea?
Car has 110K miles.
Thanks,
JP


Answer
Joel,

Check the fuel injectors by checking the fuel pressure.  If the pressure drops off really quick after you turn the key off you have a leaky injector or two.  You see, from what you say, I think an injector or two is leaking.  The fuel pressure should hold for several minutes after shutdown.  Check it out and let me know what you find.  Also, you can remove the spark plugs and if any are really black you have found your leaky injectors as basically the injectors are flooding the engine.  This is only an educated guess on my part from the information you have given so check it out and let me know what you find.
