I have a 1999 Honda CRV that stalled on the road and will not start. The starter and engine turns over and I have gas. How do I check the spark or fuel? Do I need to buy an analyzer?

That code is for the idle speed control valve. Please follow the link P0505 Honda Idle Air Control Valve

stalls, with you doing a fast rigth foot , to prevent said stall?
yes? /no?

Inside the fuel pump moduel in the gas tank is a little known part called a

FUEL PUMP CHECK VALVE ! The pupose of this check valve is to keep the fuel lines an fuel rail full of gas . Having it checked would involve hook up a fuel pressure gauge . An no it's not you starter .

The IAC [idle control motor] may be sticking. This problem usually occurs once the car exceeds 80,000 miles in service. Remove the IAC and clean it's interior with carburetor cleaner. Reinstall it using a new gasket. Sometimes, cleaning will not suffice & a new IAC must be installed. A sticking or leaking EGR [exhaust gas recirculation] valve can cause the same problem.

no the surge that high is not normal a normal cold start should go to around 1500 then settle slowly to 750 or so but this all depends on engine temp and ambient air temperature

You need to replace your coil pack. It sounds to be over heating which results in no spark being sent and the enige dies. Very common fault and easily fixed.

timing belt broke? are you getting spark? fuel?

, pull a plug wire and ground it to the engine body and check for spark. if spark then
check your fuel system pressure, fuel pump

I had that same problem a while ago. I changed the coil and the ignition and I have had no problems since. Give that a try and see if it works. I have a 1997 honda crv myself and it seemed to work.
