Its a 94 5-speed 2.2 liter, I think F22b. In the mornings it will start and die for awhile before it stays running. I was driving yesterday and it died on me about 4 times and began to have a very slight misfire sound to it. When driving on the highway it seems as if its trying to die at random times as it feels like a slight misfire or loss of power. The issue is on and off and happens a few times during the week. At idle it may seem to have a very very small miss in it randomly. It seems like something is about to give and I wish it would..

-I have changed the fuel filter, plugs, wires, cap and rotor in the past 3 months.

-I hear the fuel pump kick on along with the main relay.

-I dont think its an ignition switch although it acts just like it is. I tried starting it and holding the key in the on position and it didnt help.

- I dont know if it would be a coil, distributer, fuel relay, or whatever else? Honestly I am not sure how to check them other than replace them.

 

There are few different things it could be with quite a few testing procedures and not enough time in a day to cover them here.

Fuel Pressure Regulator can cause this too.

 

thanks guys and I am continuing to learn..

 

I claim the Main relay as the culprit. Damn Mitsubas **shakes fist in air

 

i have almost the same problem with my 94 honda del sol sohc vtech one day the car was running find and the next day i went to go start it and it cranks but doesnt turn over so i check to see if i had spark i have spark and then i put a new fuel pump in and new distibutor cap and rotor and spark plug wires and spark plugs and igination coil and still nothin it still cranks but doesnt turn over....did you think it could be my main relay??

 

doesnt the main relay click off with the engine light when you turn the key in the on position? I thought this was how it is tested...

 

Your problem is more than likely the ignitor and not the PGM-FI relay.

Yes it does a self test but it can pass that test and then intermittently fail. When it starts to get hot there are a few suspect solder joints that have been known to crack and separate at times. There is a DIY fix somewhere on H-T or you could just replace it...

Have you done any of the Ignition system test procedures form the Manual I sent you?

Have you tried to retrieve any stored codes from your ECU?
