Hi. My 96 civic won't start. I've have read so much on this site and find the information very helpful, but feel it could be a number of things. I replaced the timing belt and water pump less than 2 years ago. I would sometimes get a hesitant start on days when I let the gas tank go below 1/2. Other days I would get nothing, go in the store come out, turn key, dead. Wait about 4 min and try again, starts fine. Don't know if these probs are related to my current one. Well, one night go to leave work and no go, I did let the gas level get quite low that day. After no start I put enough gas in it to bring it to 1/2 tank plus some dry gas (Heet). Will crank, fuel pump turns on, I believe I smell gas in exhaust, check engine comes on when ignition is "on", tried to jump it, all lights work. Just won't start. I attempted to listen to the main relay, but can't hear anything, So many other beeps happening when I turn ignition to "on" position. I know very little about cars, most I've learned about my civic is on here, troubleshooting. Thank you!
