20 Most Recent 1996 Chevrolet Tahoe - Page 9 Questions & Answers

Hello,If the engine is not turning over, you most likely have a dead battery, or your starter is bad. If the battery is going dead, you will hear clicking sound and the lights will dim. If you have jumper cables hooked up between the Tahoe and a car that is already running and it still won't start, I would remove the starter and bring it to a place like Autozone or Advance Auto Parts, where they will test it for free.I hope this helps you!Mike

do you know if your switch is good? i believe your truck uses vacuum preasure from the motor to activate the front axle accuator. your problem could be the switch, accuator, or vacuum leak. vacuum leaks for 4x4 are a pain to find and follow, i had the same prob with my jeep so i ran a vacuum hose from the accuator directly to the motor to make sure everything else was in working order. hope this helps.

14 is good, (10 is bad). Any other issues with the electrical system?The gauge may just be off a little. If you put a voltmeter on the battery with engine running, it should show anywhere from about 13.5-14.5 volts. That's the alternator output to charge the battery and run the car's electrical systems.If voltage truly dropped to 10 volts when car was running, I think your check engine light would come on, and there would be serious issues with lights flickering and dimming. Check the alternator output. Good luck.

fuel pump relay?

Sounds like a fuel problem. Check for restrictions in the fuel filter and test fuel pressure.

Sounds like the camshaft sensor.

If the starting fluid works then you have a fuel pump or a fuel pump relay issue. The fuel pump relay allows the pump to come on for about 2 secs and prime the fuel system. Once the engine starts then the power to the fuel pump runs through the oil pressure circuit.
If the car starts on starting fluid and then continues to run... I would lean toward a fuel pump relay issue. Hope this helps, Good Luck!

this model does not have a cabin filter. chevrolet did not start running filters until 00 model tahoes

ARE YOU GETTING GAS ..DO YOU HEAR THE FUEL PUMP WHINE WHEN YOU TURN THE KEY OVER.

That sounds like a brake booster problem. The brake booster runs on engine vacuum to help make the brake pedal easier to push and easier to stop the tahoe. When a booster develops an internal leak, you can hear the vacuum escaping through the leak when you step on the brake. The engine stalls because the vacuum leak in the brake booster also causes a large vacuum leak for the engine.

To verify that this is actually the problem, go outside the vehicle with the hood open. Find the large brake fluid reservoir attached to a large round metal black (usually) canister on the driver's side of the firewall. (back of the engine compartment.) There is a large black rubber hose pushed into the top of the black canister, which is the vacuum line attached to the brake booster. Pull the rubber hose out of the grommet on the booster and stick your finger over the hose. Have someone start the tahoe. You will feel a considerable amount of vacuum pulling at your finger, and if you take your finger off the hose, the engine will stall. Also have someone step on the brakes while your finger is over the vacuum hose. If the noise is gone then you know the problem is in the brake booster.
Don't forget to re-attach the vacuum line to the brake booster. Failure to do this will result in the engine running very rough (if at all) and the brakes will require excessive effort to try to stop the tahoe.

• Bank 1 is the side of the engine with cylinder 1 on it.
• Bank 2 is the side of the engine with cylinder 2 on it.
• So as you are looking strait ahead at your engine the right side is Bank 1 and the left side is bank 2.

• Hope this helps and thank you for using FixYa.
