From: Ned Sanders on 29 Apr 2010 18:47 Our 99 Nissan Maxima had a severe injector o-rings leak on two injectors on a 6 cylinder engine while idling for two minutes. There was also a bottle of engine flush put in the oil pan. It flooded the engine to the point of stalling the engine. It was so severe that it won't start. While cranking it will crank several revolutions before it simply hydrolocks. I notice raw fuel spitting from the tailpipe when it idles. The center exhaust pipe was a quarter filled with fuel. I took that apart and drain it. The oil pan was drained. Two new injectors were put in, making sure it doesn't leak. The catalytic converter was removed and air dried. With the catalytic converter on or off the car it still won't idle. It will idle for 15 seconds with no knocks or pings then stalls even if I press on the gas pedal. It will easily re-start immediately but stalls after 4 seconds. All the plugs had spark and all the fuel injectors squirt fine. No smoke is seen coming from the exhaust. What part of the car is affected by a flooding that won't let it idle? Thanks

Or if you're as cheap as I am, cleaned the old ones. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

Only way fuel can go around the injectors as far as I know. Might be better to take it to a pro and get it on a diagnostic machine instead of taking it apart and putting it together again. --Vic
