      Did you already check your engine coolant level (refill and bleed the air present in your cooling system if necessary), check your thermostat if your engine coolant operating temperature is below specification and check the condition of your heater control valve operation?

      You'll need to check the components when the car won't start. It could still be the starter...

    My car suddenly idles around 1500rpm. Is this a leak or an issue with the idle air control valve?
    The onset of this problem was sudden (no major or minor car repairs). Although it is not consistently idling high in my daily driving, turning on the blower motor will cause the idle to rise again.

      Can you rephrase the question? Did you mean that while driving the engine suddenly idles? It means that the gear is slipping to neutral?

      What have you done so far to fix your vehicle? Did you already check the condition of your fuel pump and its relay?

      You might have no choice. Often I have to use one inch drive air wrench with 1500 ft lbs of torque to break it free. You could try to use the starter to break it free. Put a breaker bar with socket on the bolt and give the key a crank. Brace the breaker bar against something so it won't move. The crankshaft spins in the correct direction to break the bolt free but the starter might not even overcome that tightness. But heh, if this works, how you gonna tighten it back up? If you do not tighten it down enough, in a real short time the balancer will be loose and the engine crankshaft will be shot. Seen it happen.

      There is a special tool you can buy ton tool trucks, or special order that fits in the hex shaped socket on the crank pulley. Try getting the crank bolt hot, too.
      10/18/2010 HouseCallAuto
      I believe that the hex shaped place for that tool only began on newer Honda cars. AD makes no reference to it for '91 but does reference it on newer listings.

      Replace the main relay behind the left side of the dash. probability is 90%. Just Google "Honda Accord main relay location" in Google images. You will not do that again I'm sure.

      Have you already check the condition of your radiator fins (for any foreign objects that restrict the flow of air that helps cold down your coolant), radiator (for any clogging inside, if possible perform a radiator flush) and coolant (when did the last time that you’ve replaced your coolant? It is possible that the properties in your coolant have deteriorated)?

    I believe my car jumped timing. I was wondering if my car has an interference engine or not.
    Me and my wife was on our way home when at the stop light as I was taking off, by the time I got to 4th geer my car jerked a little then slowed down till it eventually shut off. The motor turns over but it won't fire up. I was told that it was the timing which ...

      OK thx...just wanted a second opinion. I've already replaced the timing belt and set the timing acording the proper procedure, but it still just turn over but won't crank. I believe it might be the fuel pump or a clogged fuel filter because I smell no gas or hear the pump Therefore I'm gonna replace the old pump with a new one as well as the primary and secondary fuel filters.

      Diagnose your vehicle with a scan tool to determine if there is a stored trouble code in your vehicle that can help you identify the fault to your vehicle’s problem (if the fault in your vehicle’s problem is one of your electrical control or sensor it will show in your trouble code) instead of guessing. Even if your check engine light is off don’t assume that there’s no stored trouble code in your vehicle, to be certain that there’s no stored trouble code in your vehicle you have to diagnose it with a scan tool. You can visit AutoZone or nearby auto parts store for free diagnostic.

      It is possible that fuel pump shuts down after start up. Did you check the fuel pump relay, may be defective? Or the connectors are loose or contaminated by dust.
