car cranks but dosen't start. Sometimes it will start and then when I turn it off and start it again it just cranks or I'll here a motor like sound at the driver side under the steering wheel. Its a big grey piece with a red connector going into it. What is that and could it be the source of my problems? So far I replaced the dizzy cap, ICM, and ignitionn coil. What could it be? specs, 92 hatch sohc vtec.

thanks in advance.

that gray piece with the redish connector to it is your main relay, and yes it could be the source of your problem if it's about to check out.

if you cannot hear your fuel pump priming (a humming noise when you turn your car on, not start it but turn it on) it's most likely the main relay.

The sound the main relay makes I can't even hear the fuel pump starting because the main relay is ticking, like a motorized back and forth sound and then the lights on the dash are flickiering including the check engine light. Then sometimes it just starts right up fine. Thats the symptom of a main relay failure?

 

ok so you are getting a CEL. this link will help you trouble shoot for the code.

as for the pump, if all possible, try to have someone turn the key for you and sit in the back seat. you should be able to hear the fuel pump make a humming noise. if it's not making the noise, then chances are it's your relay.

 

hmmm... I'll try that out, but keep in mind, I don't always get a cel. Only when the main relay starts acting up.

 

Mr. Roboto,

Were you able to fix this problem? If so, was the main relay the problem?

I'm having a similar problem in my 91 Accord.

Thanks.
