Mileage?..over heated? oil to top is function of oil pump and oil passageways ..bad worn lower engine (crankshaft/bearings)......oil pump push rod..under distributor driven gear down into block to oil pump in oil pan..clogged passages/oil filter/oil filter bypass...... do a oil pressure test while cranking from port on side of block low and determine if bottom end has the pressure first

Lost all oil pressure and the blazer shut off. its a 1985 2.8 v6. is there a automatic cut off in the car? And how hard is it to change the oil sending unit?


The fuel pump gets power from the oil pressure switch once the engine is started. So if oil pressure drops below 5 psi the engine should stop.
Other than a special socket to fit the oil pressure switch, its not too difficult to change.

I have a 99 chevy blazer won't start but will turn


You may have a fuel pressure problem or the secuirty system has locked you out for some reason due to a false signal or failed part. Do you have any electronic engine control codes? Is the Security light on in the instrument cluster and fishing when you try to start the truck? To check the fuel issue get a can of spray starting fluid from the auto parts store or any hardware store and spray it into the air intake of the engine while someone cranks the engine, if it starts you may have a defective fuel pump, the pump is located inside the fuel tank, the fuel tank must be removed to access and replace the pump.

I have a 99 Blazer that started leaking oil near rear of block. At that time plenty of oil pressure...I was driving to get it checked and noticed I had no oil pressure. Returned home with no problems.


The oil sneding unit is back there on top of the engine. Some times when they go bad they will leak oil threw the top/plug. This is the problem. It is about 3" long Sit in the middle of the engine all the way at the back.

Is there a reset button on this fuel pump


CHEVY DOESN'T USE A FUEL PUMP RESET/CUTOFF SWITCH, FORDS USE THIS FEATURE, ON A CHEVY IT IS DONE WITH THE OIL PRESSURE CUTOFF SWITCH, SO IF U LOOSE OIL PRESSURE THE FUEL PUMP CUTS OFF, THIS OIL PRESSURE FUEL PUMP CUTOFF SWITCH AND IT'S WIRING ARE NEAR THE OIL FUILTER UNDER THE TRUCK.

I have a 1997 Chevy Blazer that has oil, but no pressure


There's something you can do to check if the oil pump is still working screw off the oil filter and start it only for a few seconds if oil shoots out the pump is working if it doesn't the pump could be clogged or it lose prime if it's working check the wire going to the oil pressure switch may be broken.

Why wont my 99 chevy blazer temperature warm up?


You may have vapour lock in your heater lines. Start engine, put heat lever on high, disconnect one of the lines on your heater core, the one on the flow out side, & see if you have any air coming out. Once antifreese comes out stick line back on & retighten clamp. Make sure your cooling system is topped off. Also your water pump may not be functionihg to it's maximum. Take rad cap off cold & view flow rate. If inadequate you may have to replace the water pump. Good luck!

Oil pressure


At idle the oil pressure should be at least 20# at highway speed it should be at least 30# these pressures are on the low end higher is better.
