I have replaced the ignition control module, cap, rotor, plugs and wires. coil tests good.
There is a relay mounted way up under the dash on the driver side. It
is about 1"x1"x2" and it says Mitsuba on it. This is the PGMFI relay,
sometimes called the main relay or fuel injection relay. It is very likely the problem. You can buy another one, or there was a bulletin on how to repair it. You need to take it out, pop the cover off, and resolder the cracked solder joints on the pc board that the relays are mounted on. Really not that hard if you have a little soldering experience. If not, just buy another one, about 50 bucks.
The cracks are very very difficult to see, resolder or replace, especially if you already have it out, that's the hardest part. Other than that, there is at least one pick-up in the distributor and they can be a problem. If you can maybe borrow a distributor to try? Sometimes auto wreckers will let you try one.
The relay controls fuel and spark, all the sensors, cam, crank, are inside the distributor.

does the fuel injection relay control spark as well? i saw some other posts where a new crankshaft position sensor was sugested?
no cracks. relay is in good condition
the cap where spark plugs into, It has 5 wholes and the wire plugs into them,?
I replaced a v-tec engine in a 94 accord over the winter. now i have no spark. The coil checks good with 12v to the igniter. I replaced the igniter and still have no spark. I don't know what else to try? I originally wired the cap for a dl or xl. The rotor and cap are new also. Is my problem with the computer or distributor? chiltons manual no help.
I have replaced the engine control module(igniter), rotor and distributor cap. I have 12v to coil and ecm. This is a v-tec engine. What else could cause no spark? its not the plugs or wires.
