1992 honda prelude 2.2 fuel pump stays on does not shut off after the 2 second prime causing it to flood and hyper lock what would cause this?

Bad ECM or main relay. Perform the K-Test on the ECM.

How do u do a k test on 1992 prelude ecm?

The K-Test: Remove the MAP Sensor connector and turn the ignition switch to ON (Position II). Using a multimeter, check for 5 volts going between the MAP Sensor connector's reference wire (+) and ground. As you look at the connector, this is the socket on the right. Really press the black test lead into a cleaned main ECM ground on the thermostat housing. If the voltage is low, it's probably indicating ECM failure. Most failed ECMs will record a fraction of a volt. To me, the K-Test is simple, elegant, and accurate.

I changed the Ecm in my 1992 honda prelude now fuel pump shuts off now but won't start still

If the CEL comes on and goes out after 2 seconds, when the ignition switch is turned to ON (Position II), then replace the Ignition Control Module and coil:

It's firing just not starting so there's spark just won't start

Stop starting new threads.

I have spark the fuel pump is working correctly but no fuel in the cylinders could this be the injector resistor?
