I've got a 2003 Nissan Xterra 3.3 non-supercharged. The other day I drove the vehicle to the store and bought sparkplugs and a new rotor button. After changing, I have a no-start situation. I have correct fuel pressure, and I also checked every single plug wire with a timing light and ALL are working. I even re-installed all of the old parts and still had NO CHANGE. I have spark and fuel to the motor as confirmed by the timing light and the fuel pressure test. The air filter is clean, all fuses/relays are good, etc. Air-fuel-compression-spark-right????? I am very frustrated. :mad3::mad3::mad3::mad3::mad3::mad3::mad3:Maybe a cold start injector?? ANY HELP WOULD BE GREATLY APPRECIATED!!!!!!!

Stll no replies or ideas - I see.
I'm still doing some research. We were hoping that somebody had seen this scenerio before. We do know that the knock sensor shows bad - a new one is in hand.
