Would a bad oil pressure switch cause a no start on a 98 b2500


Hi,
Symptoms of a bad or failing Engine Oil Pressure Sensor
  • Oil Pressure Light comes on, and you check the engine oil level, But oil level is okay, you can blame the false reading on the sensor.
  • Oil Pressure Light blinking constantly. This is the normal >check< oil pressure sensor Warning that the sensor is going out.
  • If the sensor is giving false readings, Dispite oil level, the sensor could be replaced.
If the Sensor is currently not working, and does not warn you of engine oil level, and oil level gets extremely low, The Engine could burn up/stall due to lack of oil, and may not restart.
Then you could probably blame it on the sensor.
But really would be lack of oil.

Intermittent No Start,
Common causes deal with 3 basic systems/areas of engin
  1. Compression, its the build up of air and fuel into the engines cylinders. Then is compressed by the pistons. And is under pressure. FAILURE An Air leak (vacumm leak) will allow pressure to escape.
  2. Ignition System, good battery, good relays, wires are not loose or disconnected, good 10volts to starter, 10volts to distributer>gives 20kvolts to spark plugs>has strong spark to ignite compressed air in cylinders. Other sensors need to work. Crankshaft sensor(ccs) Throttle Position Sensor(TPS), +more
  3. Air/fuel Ratio, Air Intake Manifold, and Fuel Pressure Sensor *Fuel Injection Pressure Sensor---if car is fuel injected*, air filter is clean and intake manifold hose, Throttle Plate Acuater, Idle Air Contro Valve(IAC). Also vacumm leak cause no start. To much air not enough fuel will cause lean fuel mixter==low power, low idle, no start.......To much fuel not enough air will cause rich fuel mixter==too much fuel could cause engine knock, flooding of engine wet spark plugs, No Start
Scan Vehicle computer for Codes, Places like AutoZone---Discount AutoParts will connect scanner for free, And Code Will say What is wrong with Vehicle,

Hi I have just bought a Toyota Celica and found that the engine sump is badly dented !! I have had it inspected and I am told there is a slight leak - should I have the sump replaced or keep an eye on the...


Replacing it will provide worry-free driving, but if it does not fit your current budget and (1) it is a small leak and (2) you are diligent about checking & maintaining your oil level, then let it go for now.

Only you know if the cost of replacement is "worth it" for you. Get several competing estimates to get a true sense of the repair. If you can not check & fill the oil level as often as needed, the leak will lead to a much costlier repair.

Good luck!

2005 grand Prix oil pressure light an dinging comes on


1. Check your oil level. If oil level is not ok, correct oil level and find out why oil level was low and correct the problem. (Leaks, bad PCV, Burning oil due to severe engine wear, nobody has bothered to check it for the last 3000 miles, WAY overdue for an oil change, etc.) If oil level is ok, proceed to next step.

2. Remove the oil pressure sensor and install a manual oil pressure gauge. Run engine to verify low oil pressure. If gauge shows that the oil pressure is low, overhaul or replace engine. If oil pressure is ok, replace oil pressure sending unit and retest.

What causes the oil light to come on?


The oil light will come on orange if your oil level is low. The oil light will come on red if your oil pressure is low. The oil light will come on, then turn off if your oil level sensor needs replacing. Alex

Bmw 530i model 2001 230000 km i have to add l liter oil per 10 day due to oil leak. no oil spot under car but the mechanic told me the rubber between engine and gear box is leaking and no smoke. can...


STP won't stop the leak, only disassembling and replacing the seal. However, the car could be burning oil but the catalytic converter will complete the combustion of the 'smoke' to water (H2O) and Carbon Dioxide (CO2).

At 230,000 KM, I wouldn't be surprised that the rings are worn or the valve seals are leaking internally.

03 Mazda 6: Check engine light on, code po174


The oil pressure sensor does not have much to do with the P0174 code so the leak on the gasket is not the cause, usually it is the air mass sensor, or the intake sensor. if you have a leak of oil, this might as well mean that whoever changed the oil did not put the right specs of it and this caused the oil to get through. After some time you will experience that the rpms will reach only certain level and won't go higher. Change oil to the right specs and get the sensor cleaned if not to late or replaced (will be expensive). Gasket change wil be needed as well.

Gauges say no pressure in engine 1995 vw golf


Get someone to check oil pressure with a mechanical gauge, to verify whether you have oil pressure or not. These engine/vehicles, have 2 warning sensors & a control module in the instrument panel. Once you know you have pressure for sure, then you can proceed from there.
