Oil Level Sensor Issues

-Make sure good ground.

Good Luck

Check that the fuel tank is venting properly, sounds as though the tank is not venting therefore creating a vacuum that the carburetor cannot over come. Try running the engine with the fuel cap loose to see if that alows the engine to continue to run.

The will be a oil level sensor located in the side of the engine oil pan under the car, it will likely have one wire going to it, replace it.

A poor spray pattern in the injectors can cause starting issues. Have you tried a good (read not really cheap) fuel injector cleaner like Chevron Techron or Valvoline Synpower fuel system cleaner? A weak ignition system (worn spark plugs, leaking wires) can cause starting issues. You mentioned that it has a K&N filter on it. These filters use an oil in a cotton media to filter out dirt. Sometimes that oil can get out of the filter and contaminate the mass air-flow sensor. Follow the air tube after the filter box and you'll find a sensor in the tube with several wires running from it. It is made from aluminum and the wire housing is plastic. Remove it from the tube and clean it with a mass air-flow sensor cleaner. You HAVE to use a mass air-flow sensor cleaner specifically made for mass air sensors. Don't use anything else like carb, brake, or throttle body cleaner. Those cleaners will leave a residue on the sensor and just cause you more issues.

As for your fuel pressure, the system pressure with the key on, engine off is 60-66 psi. Do you really think you could visually tell the difference between 60 psi and 40 psi? I know I couldn't. You'll have to use a fuel pressure gauge to verify the pressure. For my money, I think your pressure is low. But, cleaning the MAF is much easier then putting a tester in, and it wouldn't hurt, so I would do that first.

check the oil level and top it up its most liky low and low oil shutdown is kicking in

if it still wont run try checking main jet , then try cleaning out carb and replacing plug

then check for tight in / ex valve s

cheers

do a full service on it , new spark plug /air filter foam , full oil change , also chane the oil in the pump end , carefully remove the carb bowl and remove any dirt/rust/water etc

ive seen gx160 engines last 10 years no problem and those were hire machines

hope this helps if it does please vote

Check and replace sparkplug. If no result, check sparkplug wire all the way to the coil, make sure no breaks and no shorts. If no then replace coil.

a coil wire may be shorting so look for damage on them!
you can sleeve them or a quality electrical tape will be ok for temp measure ok
Cheers Rob.

could be a bad coil or plug

Most honda engines have an oil sensor that prevents the engine from starting if the oil level is low or oil is dirty. Test coil by disconnecting oil sensor wire. With sensor disconnected coil should fire. If still no fire, check kill wire for short. If still no spark, coil may need to be replaced. enjoy
