if your not getting spark then your coil is the mostlikely cause it's obviously not a timing issue since you stated that the rotor is spinning. if the spark plugs are bad then replace them too . to be sure that your getting spark to all cylinders test each of the spark plugs after replacing the coil. just to besure it's not starving for fuel as well spray a little ether in the breather if it fires off right away that means the even though your fuel pump works it may not have a high enough pressure. let me know the results

Could be the ignition coil or ignition module. Also check the ignition fuse.

My daughter's 1991 Honda Accord did the same thing. I discovered that the main relay had to be replaced. Apparently the solder used in the original main relay was poor and would actually "soften" in the heat and cause a disconnection. When the cabin temperature dropped, the solder would cool and reconnect. Anyway, replacing the main relay worked. My daughter's car has not had this problem since.

Are you sure you have correct timing? its definetly a fule problem, if timing is good then turn your key to the on position and try to listin for the fule pump to prime. While the key is in on position go to fuel rail, there is a valve on fule rail called sharader valve. Get a small screw driver and press valve in to check if car has fule pressure. if pressure is present then it is incorrect timing or possible bad cam sensor.

You need to replace your Main Realy, it is under the right side of your dash.
