    Default Car sometimes cranks but won't start. Fuel smell present.

    A few days ago my 2000 CRV failed to start in the morning. The engine would crank but it just wouldn't catch. A few hours later, I tried it again and all was fine. This whole scenario repeated yesterday (i.e. wouldn't start on cold morning, starts fine a bit later).

    Last night I garaged it and this morning, it started fine but there was a very strong smell of gas in the garage.

    Battery is fine.

    My mechanic is suggesting that he change the main relay, which he said will cost about $220 with labor, but he can't guarantee that this is the problem. Does changing the main relay sound like the right first step, especially if I'm smelling fuel?

    Thanks.

    Two possible issues...

    1. one or more leaky fuel injectors, which is causing flooding in one or more of the cylinders.
    2. the ignition switch recall issue.

    I suspect #1. There are instructions in your Owners Manual for starting your CR-V when you think the engine is flooded.

    And I'd buy a couple of bottles of Techron fuel additive. Add one the next time you fill the fuel tank, then drive until you're down to about 1/4 tank left, and add the second bottle when you fill up again.
    Then add Techron once or twice a year to keep them clean.

    You can start it right away per the owner's manual (see flooded engine), then treat the problem with some Techron (or similar) fuel injector cleaner. Gasohol sometimes works as an injector cleaner as well.

    Your mechanic it thinking of the OLD Civic and Accord... CR-V never has Main Relay troubles.

    SEARCH 'flooded morning techron' and you'll understand why it always happens in the morning, or after sitting for several hours.

    SEARCH also: 'morning flooding', 'refuses to start morning', 'morning starter', 'morning failure to start'

    There's a common thread. Several years ago I replaced a Timing Belt prematurely because of your exact problem..... Then I discovered these forums, and stayed.

    Thanks to both of you. I'll try those suggestions and see what happens.

    Much appreciated.

    One additional question though... if it is a dripping or leaking fuel injector and the engine is being flooded overnight, why have I been able to start it later both times after leaving it for a few hours? Wouldn't it still be flooded later in the afternoon?

    It only takes about an ounce of fuel to swing the richness way past the too rich / won't start point. After sitting several hours it evaporates, out the open intake and exhaust valves.

    Holding the pedal to the floor tells the computer to shut off the injectors while cranking, that's why the manual tells you exactly that procedure.

    As you've seen in the other threads I pointed you to, it starts with a great puff of black smoke, and some sputtering, then everything is OK until the next time.

    well mine was kinda doing what you described, my check engine light came on and threw a code p0118 something with the radiator if i remember and if i stop the engine for gas or just to turn it off and turn it back on within a few mins it wouldn't start... it would be cranking for 15 mins (every few seconds cranking then wait a minute) b4 it starts back up. Since my mechanic told me that the sensor was shortening out and would tell the computer that its -40f outside but really its 50f... hope this might help

    Another temp sensor problem! On our CR-V, the temp sensor would say it was 40 deg F when it was hot, thus causing a hot start problem with the gas smell. Probably will become more common as the miles add up and the sensors start to wear out. Tough to quickly diagnose without a fancy code reader that can give you the temp sensor readout. This problem doesn't throw a check engine light either, and your dash temp gauge reads fine so you think the temp sensor is working, but the CR-V has three temp sensors (fan, gauge, ECM)!

    Are you sure that's not just air trapped in the head because of low coolant in the reservoir ? All those sensors depend on being immersed to work correctly.

    That's why the HONDA rad fans won't switch on no matter how much steam an empty cooling system blows past the sensors
