I went to work the other day came out to my car after working 14 hrs and car would crank but wouldn't start . Its the First time it happened .I had it towed to my house. the tow guy said it might be the fuel pump ,but after talking to some mechanics they said it might be something else. i had a problem similar to this with honda accord and it was the main relay. Not sure about the acura's though maybe fuel pump relay? thanks in advance for any help.
