Year and model?

Sudden cutoff after the car is warmed up is a symptom of a failing ignition coil. Check it first. It is on the distributor.

you might have a snapped ac belt that is tugging on the timing belt. check there.

no ac belt i think its a ignition relay, where is that located?

mosthated

1998 civic ek hatch, with b18b motor. new fuel pump , my friend says may be ignition problem but cant seem to find where the main relay is and is ig 1 under the fuse box a main relay or just ignition fuse?

I had a similar problem once was due to bad ground wire.

Ignition coil sounds like a possible one.

I'd say it sounds electrical, but I'm no mechanic.

Start here ---> ICM, coil, and fuel filter

? whats an icm? and has new fuel filter , but ill need to check the coil

Former User

The ICM is inside the distributor and tells the coil when to release its high voltage spark. Have an auto parts store test it. A bad ICM is a common cause of stalling.
