Already replaced spark plugs, fuel filter and cleaned injectors. There's gas at the fuel regulator. Any des would be helpful.

could be to many thing to take chances with, but most commonly;fuel filter,gas line antifreeze or a crack in your air intake which would take your vacuum seal away, start with the least expensive and work from their. Worst case scenario pinched fuel line

One or more of your fuel injectors are defective. I have a 1991 Olds Ciera 3.3L V-6. It had the exact same problem as your car did.I had checked the pressure,which is 40 psi at the fuel rail. I also replaced the fuel filter,checked the crankshaft sensor,and throttle sensor. Still had the same problem. Cleaned the throtte body intake. What i finally found was a bad #4 fuel injector. Take a multimeter,diconnect the electrical connectors of each injector,check the resistence of each injector over the 2 electrical connectors ,they should be between 12 and 14 omes. The ones that are NOT passing the test(or the ones that don't match up),replace. The computor (EMC) ,will not let the engine start,if one or more injectors are defective.

I'm not Roger but can tell you this....if you have a bad crankshaft position sensor or a corrupt ECM....your car will do that.....last things could be the timing belt.

Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.
