By fire I assume you mean spark at the plug. When turning the engine over with the key and the oil alert light comes on the spark is interrupted by grounding the system thus the engine cannot start.
First, look at the obvious things, check oil level if it is at the recommended level smell the dipstick if it has a strong smell of gas
change the oil and try to start it again. Be sure the plug is not soaked with raw fuel before you try the restart. I the problem persists you can disconnect the wire from the top of the low oil sensor.Try to start the gen. if it starts change the low oil sensor.
I hope this all makes sense to you , good luck with it.
i usually do a quick test of a small few onzes of fuel down the plug hole and reinstal plag and see if i9 fire up and run for a lil bit. maybe 5 -10 seconds. now i know i have spark . most usually our wonderful fuel is the problem. its just nasty now. it can stick a needle to the seat. it can hold her open . one way ya flood out. the other ya starv out. give it a try.
Code 32 is a low cranking speed sense. You didn't mention a Spec # which would help. You say batteries are ok, but the generator is not getting enough cranking amps or voltage to maintain the control properly. Check, battery voltage, wiring, any in line isolation solenoids, check generator solenoid, also make sure there is no mechanical binding on the generator, a good way to do that is remove the spark plugs DISCONNECT THE BATTERY to prevent starting, underneath where the air intake is under the alternator is a plastic plug, remove that and you can put a socket I believe 3/4" up onto the alternator shaft and rotate the engine, if it tuns freely there is no binding, if you feel it is hard to move, check the drive train, belts, pulleys underneath (A lot of work, best to take to a dealer if it is mechanically bound)
I have a EM5000SX. My problem is my generator will not start unless I turn the fuel selector to off. Then crank it until it does start, turn the fuel back on. Run's normal . I run this generator for my cabin every weekend.
Make sure that the generator is full of oil. It has a low oil level sensor that will ground the spark if the oil is low. If you have filled it to FULL with oil and still have the problem disconnect the low oil level sensor (one wire) and check for spark again. IF you now have spark the oil level sensor has either failed or is dirty. (yes you can clean them with carb cleaner.)
If after doing the above you still have no spark... I need 2 things.
1. the actual model number off of the generator Will start with PM or PMO
2. the engine model number / type / series number off of the engine
Always troubleshoot with new sparkplug. Remove the oil sending unit connection from the coil. The coil should work without any wires connected. Usually the only connections are oil sending unit that will short to ground when low oil condition and other wire must be kill wire to on/off switch. Use carb cleaner spray directly into the carb with air filter removed and choke off as fuel supply. Just a short spray and another short spray after a couple of pulls. If engine wants to start you will need to keep spraying cleaner for engine to continue to run. If engine wants to run, replace fuel with couple gallons of premium fuel to get it going. Hotter fuel will help if the compression is low. Good luck
1. Fuel selector: ON
2. Start run sw: ON
3. Oil Level : Full
4. Choke selector FULL ON for no more than 2 pulls initially The half choke then off
5. Spark at the Spark Plug YES? NO?
a. No spark suspect low oil level sensor is grounding the ignition either due to low oil level or it just is not working properly.
After doing all of the above...
Spark Plug WET or DRY? Dry and still won't start check fuel supply. If you use the choke with the start run switch in the off position the spark plug should get WET. Spark plug does not get wet... with choke on and ignition off. Fuel supply problem.
At this point I suspect either the Oil Level is incorrect or... that the FUEL SELECTOR is OFF.
