Check the oil level in the engine. If it's low then add some oil. If oil level on the dipstick is between full and low then you better have a mechanic look at it, could failed oil pump.

The oil pump can be changed without pulling the engine.

The impressive looking thing is the balance shaft assembly. These counter-rotating shafts balance out the inherent vibration of the engine. You can remove it, as long as you do not disrupt the gear placements relationship to each other. The balance assembly is set to a specific point.

HI. this could be a faulty sensor or a bad oil pump screen as well. the oil pump malfunction is the worst scenario in this case. You can actually test the sensor with a voltage needle to see if its getting the proper voltage. i would inspect the wires that are attached to the sensor as well. if the wires are good and the current level is ok as well, it will most likely be a faulty oil pump or bad oil pump screen as well.

In this case, i would recommend inspecting the oil pump assembly. here is a inspection guide below that will help you confirm oil pump failure.

--OIL PUMP INSPECTION GUIDE--

  1. Clean the oil pump components with non-corrosive solvent.
  2. Dry the oil pump components with compressed air.
  3. Inspect the housing and the cover for cracks, scoring, casting imperfections and damaged threads.
  4. Inspect the gerotor gears for chipping, galling or wear.
  5. Inspect the pressure relief valve for embedded particles and/or damage.

The internal parts of the oil pump are not serviced separately. If wear or damage is noted, replace the entire pump assembly.

Please rate and have a great day:)

I really doubt if your motor siezed up while sitting there. But your battery could have gone dead, or your stater may have locked up, or a battery cable is loose or dirty.

My 2005 Cadillac CTS ran out of gas the other day. I filled the tank about half way. Now my car will crank but won't start. What do you think can be the problem?


I think you damaged the fuel pump by letting it run dry. It needs gas to keep it cool. But check fuel pressure. If you have low or no fuel pressure, you'll need a new pump. Figure around $800...pretty high price to pay for letting it run low on gas

I drove my dodge Durango to day and when I got home I turn it off got out ,got back in to crank it up and it just kept turning over it never did cauth why


Remove the gas-cap, to ventilate the gas tank,
to equalize the air-pressure inside/outside the tank.
Too-low air pressure means that the fuel-pump cannot send any gasoline to the engine.

Replace fuel injector cadillac cts 3.6


First off..Do you have the High Pressure direct injection 3.6 LLT engine or basic 3.6 Engine ? Yes the upper Plenium has to come off, but you will have to probably pull your wipers off, and the 7mm screws that hold the cowl beauty panel on and then there is enough cleareance to remove the plenium, disconnect throttle body snorkel tube at throttle body, remove 10mm bolt at brkt drivers side of throttlebody (ball stud) if I remember right, then there are 13mm bolts at back besides the obvious ones you can see and carefully lift it up off engine, thenyou can get to rails for the injectors, to bleed off 3.6 low pressure fuel system pull fuel pump fuse in trunk fuse box and start it let it run out of gas, then bleed Schrader valve too on rail, if you have a high pressure direct injection llt engine let me know, will describe procedure to you

I have 55,688 miles on my 2003 CTS. The low oil pressure/stop engin warning light comes on after I have been driving for 20 minutes or so only when car is idling at stop signs. The oil registers full and...


The oil pump could be bad, or going bad. Oil pressure is effected by wear on the crankshaft main bearings and camshaft/s bearings. If those bearings are bad, that would make it lose oil pressure, but I wouldn't think it's time for a new motor at that mileage!!! I would find out what the actual oil pressure is, using a "wet gauge" or oil pressure gauge. The oil pressure sending could also be bad, giving false readings.

Will not start when hot. starter makes no different types of noise.


hello. perhaps I can assist you.

Perform this test:

Fuel pump test:

1. Get yourself a helper.

2. remove the gas cap.

3. have one person listen in the gas tank at the gas cap opening.

4. have the other person turn the ignition switch to the ON position ONLY so as the dash lights come on. Do NOT attempt to start the engine.

5. As soon as the ignition key is turned to the ON position, The person at the gas tank should hear the fuel pump run for TWO SECONDS and then it should STOP.

6. Does it ?.


If you do NOT hear it run, in most cases the fault is the fuel pump relay or the fuel pump..


As soon as you turn ON the ignition switch to start the engine a 2 second ONLY battery voltage signal is sent from the computer to the fuel pump relay and from the relay back to the fuel pump in the fuel tank. This runs the fuel pump for ONLY 2 seconds of which pressurizes the fuel system in preparation to start the engine.

Once the engine starts, The computer BYPASSES the fuel pump relay and sends constant contionous battery voltage from the computer to the oil pressure switch of which is now CLOSED because the oil pressure is UP because the engine is running. Therefore the battery voltage flows thru the oil pressure switch back to the fuel pump to run the fuel pump constantly until you turn OFF the engine.

the sensor is wearing out, that causes the gas not to back flow, or you need a new gas cap(pressurized). I would get a GM gas cap, because the after markets aren't that reliable for your car.

ok, woodhujr,if im not mistaken you had another help request of cranckcase pressure...that problem is causing your leak.
ccny, i have no idea what you are talking about, feel free to enlighten us...
Howard, the best advise i have for you in replacing the valve cover gasket(s) is to get a repair manual for this car/engine and follow the steps as outlined there. I couldnt try to give you step by step instructions in this little box without way oversimplifying.
