buggyjune009, you don't want to keep opening new threads.

I realized after I did it,any idea as to why I'm getting fuel to 3&4 cylinders but not 1&2.The car had no problems before it quit running,smoking,idle issues,nothing out of the ordinary.ECU not giving me any trouble codes.

Most "crank but won't start" situations are electrical-related (90% plus), not fuel . Have you replaced the Ignition Control Module and coil with NEW components:

These are two of the most problematic components on your generation Honda. Plugs 3 and 4 may not be firing properly (hence, wet). It's not common to have injector problems on Hondas. Apparent fuel problems (effect) usually have an electrical basis (cause); e.g. main relay, fuse, ECM, ground, ICM, or coil.

Does the Check Engine Light come on for 2 seconds and then go out, after the ignition switch is turned to ON? During this 2 second period, do you hear the fuel pump run?

I would still replace the Ignition Control Module. This is the most trouble-prone component, which should be replaced every 120,000 miles or 10 years--whichever comes first. You can have spark, but it's not firing at the right time. It needs to fire when the ECM directs; otherwise, the car won't run. ICMs have a microchip inside that gets destroyed by heat.

I'll try that and get back to you thanks for the info

Okay.

Plugs 1 and 2 are dry, because they are probably firing, while plugs 3 and 4 are wet, because they are not firing. It appears you were interpreting the results incorrectly. Most cars suddenly die and need to be towed home, because an electrical component fails.

Good job--glad to hear it. Start using full-synthetics in the engine and transmission and keep it going a long, long time.

Put a timing light on the car, now, and "nail" the timing:

Already done I only use amsoil or royal purple in everything I own.Amsoil in daily drivers and royal purple in the street machine.

Smart choices! In my opinion, it doesn't get any better than Amsoil and a premium oil filter.

Be sure to change your brake/clutch fluid every 2 years.
