Fuel Pump Changed

I changed the fuel pump of my Honda Civic 1.6 (1993) model recently. After changing the fuse, spark plug, and checking the wiring, I still cannot start my car engine.

1. Your fuel pump is mechanically operated, if I am not mistaken. And if you could remove the hose connecting it to the carburettor and crank the engine, fuel should flow out. If no fuel flow out, then check the pump or replace it with one that you are sure is working. Also, have you connected back the hoses correctly and not reversed the connections?

2. If there is fuel coming to the carburettor and the engine is cranking but not firing. Check if you have any spark to the spark plugs. An easy way is to pull off one of the spark plug leads and connect it to a spark plug and lay it anywhere on the engine for an earth connection. Crank the engine and see if there is any spark at the plug. If there is not , then you need to check the ignition system, from the ignition switch to the coil and the distributor.

When an engine does not start, you have to sort it out by a process of elimination and do not assume anything. Often when one does some work, one may accidentally disconnect some wire or forget to fit one back and so a systamatic check is necessary to get it started again.
