Re: will engine run with plug wires in reverse firing...
If they wasn't almost rught it wouldn't run at all. Pull them off one at a time and see if it makes a difference while its running the ones that don't make a difference is the ones that are wrong. Check while its running even if you have to use insulated pliers. Then get back with me God Bless

Your Cutlass is either the 3.1 V6 or the 3400 Dual Overhead 24 valve V6...each motor is clearly marked on top of the engine plenum. If you have not changed the plugs yet...I recomend you do that at the same time...you can purchase inexpensive replacement wires with a limited lifetime warranty...be sure to compare. No special tools needed to switch out the plug wires...I highly recomend using plug wire boot lube grease to assure good clean water proof contact...also helps ease od service later as needed. The lube is only a couple of bucks...Be sure to ask the parts person the ignition firing order...this will help to confirm proper installation...Remove only one wire at a time...this insures you maintain the current firing order...remove and replace only ONE wire at a time...disconnect from the plug, then trace to the coil pack, and disconnect...replace with similar length wire using lube grease on both end connections...Plug wires and plugs should be replaced on your Cutlass OBD I motor by 100,000 miles...they can wear out and leak or misfire prior to that...Your motor is also sensitive to a clean Idle Air Control valve...about $35. or try to clean the old one and mounting hole with injector spray cleaner and wipe out...Also check for any vacumn leaks while changing wires...the old rubber lines and connections crack and leak with age...The Cutlass is usally a reliable long term car...Good luck with yours. Hope this helps.
DID YOU GAP PLUGS CORRECTLY? CHECK TO MAKE SURE SPARK PLUG WIRES ARE IN RIGHT FIRING ORDER QUESTION DOES ENGINE TURN OVER LIKE IT WANTS TO START???? CHECK ALL FUSES SOME HAVE STARTER RELAY FUSES ALSO MAKE SURE TRANSMISSION IS FIRMLY IS PARK MAY HAVE A STARTER SAFETY RELAY CAR WONT START UNLESS PARK IS ACHIEVED.....GOOD LUCK
Normally the firing order will be stamped on the top of the intake manifold also the number one plug will be the front one on the drivers side of the car. On the top of the distributor cap you should see a number one that is where the number one plug wire goes follow the firing order on the manifold and go clock wise on the distributor cap
