Your fuel pump power is controlled through the oil pressure switch, and if it is showing low pressure due to a leaking/defective oil pressure switch, it may shut off the fuel pump. Oil pressure switch failures are a common source for oil leaks. There could, and probably are, other issues going on. You never mentioned if the "check engine" light was on, and if it is, a scan would definitely be in order to determine the true cause of your problem
If it is not on, GM fuel pump failures are very common, as well as the vehicle security system my be having a programming issue. I would start by having the engine scanned (most Autozone locations do this for no charge) Good luck!

SOURCE: Oil pressure switch

There are no recalls that pertain to oil pressure switches on any Toyota vehicle. I would like to know exactly what part of the switch popped out, the entire switch, or just a part of it. What probably happened is somebody banged into the switch when changing the oil, and compromised the integrity of the switch. The oil pumping out issue: The Oil Pressure Switch is on the first oil galley out of the oil pump. This means that the switch port gets full oil pressure while the engine is running. This is around 30 PSI. With the switch, or any part of it missing, it would not take too long to pump out the 3.9 quarts of oil in the pan.

SOURCE: like 3 days after i got my oil changed in my 2006

This is an idication of a severe oil leak. Check the oil level in your engine to see if there is any in it. Add to the full mark and return to the oil change shop and ask them to see where the leak is. Do not operate without oil. Severe engine damage will occur. Hope this helps Moe

SOURCE: F250 spins over well will not start

Sounds like a faulty crank sensor. Can also be caused by a faulty cam sensor.

SOURCE: A light comes on in my car that says oil pressure

If the light is only turning on during acceleration or deceleration and then goes off, this is normal. If the light is constant, and you are sure you have oil that is up to the "full" or "max" level on the dipstick while hot, then it might point to a faulty oil pump or worn gaskets that will no longer prevent the oil from staying in place in the engine. Is this light accompanied by a check engine light. If so what is the code. You may also have a faulty oil sensor. Hope this helps

On a 06 Chevy Impala 3.5 what do I need to change when the car shuts off and across the dash it says starting disabled service throttle and the oil light come on and it says low oil pressure engine


Newer cars use what is referred to as "Drive by Wire. Instead of a throttle cable that goes to the throttle body, there is a sensor on the gas pedal and another on the throttle body. The signal from the pedal is sent to the ECM, analyzed, and transmitted to the throttle body to perform the desired operation. If something in that chain breaks down, the car is disabled as a safety feature, so that you wouldn't have, say, a wide open throttle issue to deal with. That is what the "starting disabled, service throttle" means. As far as the oil light and low oil pressure indications, if the key is on, and the engine is not running, these are normal indications since there is no oil pressure in the engine when it is not running.

My 2006 impala had low oil level so i added a little too much. Now low oil pressure shut off engine light comes on. what is causing this? is it the oil pump?


Not Likely. You need to have an oil pressure test performed. If the pressure is low than running the engine low on oil has caused excessive main and rod bearing clearances. having the engine rebuilt is expensive. Either install a known good, used engine or get a re-manufactured engine w/ a good warranty. The best reman is made by Jasper Engines and Transmissions and come w/ a 3 year 100,000 mile warranty.

2006 chevy impala traction control


Reduced power is a problem with electronic throttle contol . drive by wire . Do you know what this is ? Taking the vehicle an having it hooked up to diagnostic tool an checking for DTC'S - diagnostic trouble codes is always a first step when trying to find the root cause of any trouble light ! And not auto zone , pep boys , or advance auto parts . Thier diagnostic tool will not check codes in all system control modules .

I got code p2176 I changed out the tps still got same problem did not have this problem with other engine just changed engine out now cant seem to get this code off causing the car to rough idle and low...


P2176=Throttle Actuator Control System - Idle Position Not Learned
Did you use all you old sensors,or is some of them from the new engine,I would swap out the IAC sensor or check for wires not hooked up.
If it can't relearn to idle the Idle air control might be different then your old one,but its not registering with the computer
