Question about Cars & Trucks
I perchase a cylinder compression tester from ebay i use about couple of time it was working good but now the gauge drop to zero with out touching the release valve what could be the cause?
burned valve is likely the culprit.... or bad rings.... hook air up to that cyclinder one at a time.... and listen where the air is escaping... be aware that the motor will rotate till the piston is at the bottom of it's rotation. if it's a burned valve you will have to remove the head and replace it but somewhat easier job then replacing the rings. darn almost forgot.... it can also be a blown head gasket.... same procedure but you might need a brush and some soap water to test for an air leak at the side of the head. when you are done spray some wd 40 on it to get the water off so the spark plugs do not arc.

Hello, let's see what you need.
Yes, the pump can go out that fast.
Do not start your engine. Go out and check the oil. If you have plenty of oil you will need to tow it to a shop. If your out of oil check the the drain plug on the oil pan and check the oil filter.

I am not really familiar with the setup there but I'd be looking for a second relay to kick the pump on when cranking.

the sensor is on the side of the engine block. there's two thing that monitors oil. a pressure switch turns you oil light on and you oil pressure sensor the operates your gauge, start with your sensor. that is near you oil filter that is where it gets it pressure reading from

when u press the gas pedal to go this opens the throttle valve, the idle speed of your engine is computer controlled, this is done by the ISC (idle speed control) airbypass valve, these parts get full of gunk and then get a stalling problem at or near idle, clean them by doing the following, if u don't understand the instructions seek help from your friend.
, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
