Need Help ASAP
i have a 94 civic dx.Im having trouble on cold start-up..just replaced fuel pump,fuel filter,wires and plugs.I can hear the fuel pump and relay cut on but when starting it sounds like the engine is flooded and just turns over...Any suggestions on what to check
First, is the CEL ON (see link below)? If so, retrieve the trouble code.
If the CEL works and is not ON, then:
1) Check for spark
2) Check the fast idle valve (remove and clean with carburetor cleaner if it's not functioning properly):

Is the CEL ON in the gauge assembly?
Normally, when you turn the key to ON, the CEL turns ON for 2 seconds then turns OFF. If the light remains ON , then a trouble code is stored in the ECU. If so, retrieve the code as described in the link found in my signature.

Pretty much. Test spark at each plug as follows:
When engine won't start, remove a plug wire and insert a spare spark plug into the end. Ground the threads of the spark plug at the end of the wire on a convenient metallic part of the engine and have a buddy crank the engine. If you see bright blue sparks at the tip of each plug, then spark is fine. Next test the fast idle valve.
By the way, your plugs and wires could be fine, but you could have a bad component in the distributor.
