Hello everyone. really wish not bother you guys too much. I had a 240SX about two years now. However since last time had a fuel injector issue, I haven't start the car about a year. Now I replaced fuel injector, spark plugs, ignition wire. the car cannot start, or I'd like to say car starts, but cannot even reach idle speed, felt like only one or two cylinder is firing. after I remove the spark plug to inspect it. I noticed one spark plug already all the way turned to black. One is still like new. And I can smell gas from cylinder also from exhaust pipe. I am really confused now. Anyone can tell me what's next step is? My 240sx is a 1991 240SX manual with only 40K original miles, also I live in DFW area. Thanks guys. Mahalo!

Did you accidentally change your spark plug wires around? It almost sounds like it is firing out of order.
If you think you are running rich, try pulling your fuel pump fuse to see if there's a time when the car runs normally prior to running out of fuel pressure and dying.

Thanks Bro reply my post. I checked my wires, I think should be connect correctly. My car can fire up, but I have to push the gas paddle down. Also the car is shacking so bad, and felt like only one cylinder is firing. At last, there is gas spill from the exhaust pipe with white smoke.
