My 2003 chevy tahoe won't start in the morning


Many possible causes....Too little info to make an intelligent suggestion. Try charging the problem vehicle's battery with jumper cables for 2 minutes with the supply vehicle running at fast idle (or about 1500-2000 RPM, if it is tachometer equipped) before you try to crank the problem vehicle on a cold morning. If it starts right up, you likely have a weak battery that needs replacing.

Replace the oil sending unit mounted on the engine. It also works the fuel pump when starting the engine to prime. It will have three wires going to it

Tahoe won't start


Is your security light flashing? If your Tahoe has the factory ant-theft system, if the security light is flashing while you are cranking your anti-theft system has been activated. It is common for the Tahoes to wear out the ignition lock assembly, lock cylinder and the ignition switch(electrical) which is attached to the lock assembly. I have replaced all three parts with great success and solved the no start problem on several GM trucks.

The most common problem with these vehicles is the fuel pump. The pump should run for a few seconds when you turn the key on before you crank the engine. If you don't hear the pump run, go to the fuse/relay box under the hood. Look at the diagram on the inside of the lid and locate the fuel pump fuse and relay. Check the fuse to see if it is blown put it back if OK or replace it. Unplug the fuel pump relay and use a paper clip to jumper across terminals #30 & #87 where the relay plugs in. If the fuel pump starts running, you should be able to hear it run at the back of the vehicle, where the tank is. If you don't hear the pump running, hit the center of the tank dead-center with a rubber or wooden mallet. If the pump still doesn't run, see if you can get to the wires going to the fuel pump and wiggle them. If you hear the pump run, try starting the engine. If it starts, replace the relay, if that was the problem or the fuel pump AND relay if the fuel pump was the problem. WARNING! WHEN YOU UNPLUG THE PAPER CLIP. IT MAY BE HOT!!!
The fuel pumps AND connector are big problems with GM trucks. If you replace the fuel pump(which is located in the fuel tank), use only the factory pump which you can buy at your GM dealer or an auto parts store that sells Delco parts. If the fuel pump used the small square four-pin electrical connector, replace it with the fuel pump. The latest GM/Delco fuel pumps will come with the new plug which you MUST change over as it is now a flat four-pin connector.
GOOD LUCK!
