You might have a bad spark plug or plug wire. I know this may sound silly but make sure the unit is full of oil. It has a low oil shutdown that will kill the ignition. You might check the wiring and make sure that it is all connected. Especially the wires going to the ignition switch. These are great generators. Good luck.
The low oil pressure warning lamp will illuminate when the ignition switch is turned to the
position without the engine running. The lamp also illuminates
if the engine oil pressure drops below a safe oil pressure level. To
test the system, perform the following:
Turn the ignition switch to the
If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
If the wire at the connector checks out OK, pull the connector
loose from the switch and, with a jumper wire, ground the connector to
With the ignition switch turned to the
position, check the warning lamp. If the lamp still fails
to light, check for a burned out lamp or disconnected socket in the
REMOVAL & INSTALLATION On the
2.4L engine, the oil pressure switch is located on the side of the
engine block facing the firewall. On the 3.0L engine, the oil pressure
switch is located on the oil filter adapter housing, next to the starter
motor. On the 3.3L and 3.8L engines, the oil pressure switch is located
next to the oil filter.
Locate the oil pressure sending unit on the engine.
Disconnect the negative battery cable.
Disconnect the pressure switch electrical harness.
Using a pressure switch socket, deep-well socket or wrench, loosen and remove the pressure switch from the engine.
Install the pressure switch into the engine and tighten securely.
Attach the electrical connector to the switch.
Connect the negative battery cable.
Start the engine, allow it to reach operating temperature and check for leaks.
These units are equipped with a low/no oil shutdown. When you hold the switch over to start it, it overrides the shutdown interlock until the unit builds oil pressure in the engine. When you release the switch to the run position the interlock is engaged. Ensure there is sufficient oil in the crankcase, check the wiring from the oil pressure switch to the ignition cutout-(it may have been pulled off or damaged). If that checks out, then either jump across the 2 wires at the oil sending unit or disconnect the harness from the sending unit to test to see if the sending unit is bad. Try both unless you know the switch is normally open or normally closed. Replace the sending unit if needed.
It is very likely you are having a problem with the low oil pressure switch or the high temperature switch. Both of these are connected to the No.85 wire which in turn goes back to the control board. If the temperature exceeds the predetermined level (apprx 305 degrees F) the high temperature switch will then ground wire 85 causing the unit to shut down. Same thing with the oil pressure switch, if the oil pressure switch goes below 10 psi the low oil pressure switch will ground wire 85 causing the unit to shut down. To determine which is causing the problem disconnect first the low oil pressure switch (Located by the oil filter) and start unit if it contunues to run after 10 seconds and does not shut down then the oil pressure is the problem. Then you must use a mechanical pressure gauge connected where the low oil pressure switch is to determine if you actually have less than 10 psi of oil or if the low oil pressure switch is just bad. Try the same thing with the high temperature switch also located close to the oil filter if you disconnect it and it continues to run more than 10 seconds then you have and engine that might be overheating. Anything that gets caught in the air intake on the generator itself ill cause this unit to overheat, I've seen it **** garbage in through the air intake and cause the unit to overheat because of poor air flow. If their are no restrictions and you have good air flow than chances are you have a bad high temperature sensor.
From the key switch you need to run a power wire to the coil positive post.Then the coil negative post goes to point in the distributer.If you don't have an ignition post on the switcn the it gets it's power from the oil pressure switch that will power up the coil as sone as you have oil pressure.Let me know if you need more help.
Your oil sensor is detecting a fault condition, or has become faulty itself.
Normal operation is that the rocker switch breaks the wire going to the sending unit so that engine will try to start. But, once started, if fault exists, the sending unit disables ignition.
Depending on model, the sending unit may detect low oil or low oil pressure. Either way, there is a single wire going to the sending unit, typically located near the oil filter (if equipped). Follow the wire, and you will come to a connector inline that you can pull apart. If engine runs now, and you are sure that you have proper oil pressure and level, then sending unit is bad. Don't run engine without making sure you have proper oil though. You can burn it up in short order.
i would check the wiring going to the oil pressure switch. i had the same problem in my 95 deville. it was the signal wire touching the ground wire. in witch completed the curcit and turned the warning on. so check thair. if all is good. do an oil change reset the oil life.
