2002 trailblazer oil pressure drops when stopped returns accelerating


Usually means the engine bearings are worn out, or the oil pump is weak.
As the oil gets hot, it gets thinner, which reduces pressure. When the engine is at idle speed the pump is not pumping as fast as it is at highway speed.

How do you replace an oil pump on 2002 Chevy trailblazer


The engine is shot. Throwing an oil pump on it , is throwing away money and time. Oil pumps rarely go bad. Pull the oil cap, if the is sludge on it, it is way worse inside the engine. You'll clean it and slap on a pump. Only to find out the crank bearings are worn out and it starts knocking. Change the oil, add oil additive to it and drive it till it dies. Then scrap it or replace the engine.

Oil pressure low stop engine and check guage


Fist check oil level, the sensor is a pressure switch worked by oil pressure, hopefully the sensor has gone faulty. The oil pressure needs checking, if the oil pump or relief valve has gone faulty, the engine is being starved of lubrication and is causing internal damage. It is advisable NOT to run the engine till the pressure has been checked. (hope it's the sensor)

THE OIL PRESSURE GAUGE DROPS TO ZERO AND LIGHTS ON THE DASH FLASH WHEN STOPPING ON MY 2002 CHEVY TRAILBLAZER


poor oil circulation may need either more oil or a new oil pump, any other symptoms?

It could just be the pressure sensor, as this is cheaper get it looked at first.

Hope this helps

In my 02' Trailblazer oil pressure gauge goes below 0


I have this same problem with my 2002 trailblazer; however, I goofed up and had a mechanic look at it, since I was perplexed as to what was going on with it. He told me the oil pump needed replacing and it ended up costing me around a $950. Needless to say, it still happens. A grand down the drain - it wasn't the oil pump. The oil level is always good. This generally occurs when I've run the vehicle for a while and then come to a stop. It occurs quite often during the spring/summer and doesn't happen all that much during colder months.

Where is oil pump on a tril blazes 2002


Your oil pump is mounted to the underside of your engine block, inside the oil pan. To say it is buried would be an understatement. Depending on clearance to remove your oil pan, you may have to pull the engine to gain access.
