Default My Honda accord still won't fire,up(1990 EX)?

replaced main relay, distributer assy.,fuel filter,checked computer under dash board passenger side,fuel is flowing but not squirting,but no spark...does an oxygen sensor have anything to do with this, or was the main relay installed wrong,I just screwed the new one in and plugged up and tried to start the car........

From my experience, most "no start" Hondas usually end up being an ignition coil, that is if the coil is internal to the distributor. Easy to tell, if you only have four plug wires, its internal. If it is, there is a metal plate between the coil and the distributor housing. The plate act as a ground and simply grounds the voltage that the coils generates to the distributor housing and not the rotor button....and eventually the spark plugs. Usually if this is the problem, when you remove the coil, pry the metal plate formed to it, there will a white-ish sunburst pattern trace evident (not always true, but most of the time). Just be careful removing the small screws holding the two wires onto the coil. They round-out very easily which is something you don't want to do. Note: never, ever use aftermarket ignition part on a Honda. Not even plug wires. I have fixed alot of Hondas through the years by simply installing Honda parts in place of aftermarket. Don't get me wrong, if a aftermarket part will do the job well and cost less, I will use it, but with Honda ignition parts, you usually end up installing a problem rather than a fix. Don't worry, a coil for one of these from Honda is less than $100.Second most common cause is the ignitor.
