Hard to start my 96 Acura in cold & humid

(1996 Acura TL)
in San Francisco, CA on September 04, 2009
I found my 96 Acura 2.5 TL is hard to start in the morning when the air is cold and humid. I live near oceanside and generally park my car on the driveway. The problem occurs about 2-3 times per week.

The battery had been changed and the car had been tuned-up about a year ago in an auto shop. The spark plugs and wires should have been changed, but recently I have found "2002" marked on the wires. Don't know if it means the wires were made in 2002.

When the air is cold and humid, it always takes me 3-4 times to ignite the engine, looks like stepping on gas pedal helps a little bit. The engine will eventually start, but now it takes me longer and longer to get it started. And there is a heavy smell of gas right after I it is ignited. The car just runs great as usual for the rest of the day.

I tried WD-40 around the distribution caps and fuel-injection cleaner. None of them helps to relieve the problem. It's my only car and I'm tight in budget to fix it. Please help! Thanks!

I have the same year/model of car. The fuel filter is very assessable in the engine compartment. I would put a fuel pressure gauge in the banjo fitting on top of the fuel filter fitting start the car, switch it off and start the car first thing the following morning and see that it quickly builds fuel pressure and the pressure is adequate. As a tune up item this car has adjustable valves (often over looked as part of a tune up). How are your plugs? Could there be oil inside the distributor cap (the distributor is in a very hot place in the engine compartment.
Your car has On Board Diagnostics, the connector is behind the ash tray. A scan tool can be attached to monitor engine sensor data to see they are within specification. Ensure the air induction boot is not cracked and is firmly attached to the intake manifold.
