Can oil pressure switch be affected when rep;acing sparkplugs and wires on 1993 ford ranger 3.0 motor?

You probably knocked a wire loose for the oil pressure guage when you were changing the plugs. Check all connection and it should work.

Describe your 3000 Watt Portable Generator Problem not getting spark to the plug i know that much because i pulled plug and cranked over nothing but i did get zapped when held plug wire in my hand just...

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.

I need to know where the oli sending unit is and how to replace it?


Fig. 1: Location of the oil pressure switch-3.3L and 3.8L engines


Fig. 2: Location of the oil pressure switch-3.0L engine


Fig.: Oil pressure switch (sending unit) schematic

The low oil pressure warning lamp will illuminate when the ignition switch is turned to the ON 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:

  1. Turn the ignition switch to the ON position.
  2. If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
  3. 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 the engine.
  4. With the ignition switch turned to the ON position, check the warning lamp. If the lamp still fails to light, check for a burned out lamp or disconnected socket in the instrument cluster.

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.
  1. Locate the oil pressure sending unit on the engine.
  2. Disconnect the negative battery cable.
  3. Disconnect the pressure switch electrical harness.
  4. Using a pressure switch socket, deep-well socket or wrench, loosen and remove the pressure switch from the engine.
To install:
  1. Install the pressure switch into the engine and tighten securely.
  2. Attach the electrical connector to the switch.
  3. Connect the negative battery cable.
  4. Start the engine, allow it to reach operating temperature and check for leaks.
  5. Check for proper oil pressure switch operation.

Hope this helps (remember to rate this answerr).

Hello, I have a Briggs & Stratton 7000 watt generator Home Standby with manual transfer switch, it starts but when you release the switch into run mode it dies, any ideas? Generator has been in service...

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.

My 40g shuts off after running perfect for a feww minutes

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.

Hope this helps, please let me know.

Yamaha 6500 watt diesel runs but usually shuts

First thing to monitor is the fuel solenoid power. See if it is the thing that goess away to cause shutdown.

Tracing this back there is only a few things that control this: The battery, the low oil shutdown switch, and the run switch, and associated wiring.

If I were to ventture a guess, I would put money on the low oil shutdown switch.

Starts and will run as long as i hold in start button

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.
