Engine will not start
'94 LX 3.8L V6
It has gas in it
New fuel filter, PCV Valve, and IAC (Idle Air Control valve)
About 2 months old: Autolite wires, Autolite double platinum plugs, rotor and cap.
What I've tried: Cleaned the ignition coil. Pulled wire from #4 spark plug and attached one of the old spark plugs to it and held it against alternator for ground and saw a spark when trying to turn the engine over. The starter does run, engine cranks over but will not run... cleaned throttle body and sprayed carb cleaner into it and tried to start the motor, still does not run. Checked to make sure all wires have good connection, all hoses properly attached...
Any suggestions?? what could possibly be the problem?? I was going about 70 on the highway when it just stalled and hasnt started since then. Thanks
