Well the third ingredient is compression, but I will assume you have that. You say you have spark, so I will assume you checked for spark at the plugs. How do you know you have fuel spray at the injectors ?

You either have a bad plug wire or have cracked one of the new plugs while installing them. Try watching under the hood while someone else accelerates the engine to locate the noise.
Good luck dont forget to rate.

1. Close all vehicle doors.



2. Insert the key into the ignition.


3. Hold down the power UNLOCK button on the driver’s door panel-continue to hold
down until instructed to release in step 9.



4. Perform steps 5 through 8 in fairly rapid succession.

engine).



6. Turn the ignition switch to the OFF position.


7. Turn the ignition switch to the ON position.


8. Turn the ignition switch to the OFF position.

SOURCE: replacing spark plugs in a 2002 chevy tahoe

EACH ONE OF THE SPARK PLUGS IS LOCATED UNDER INDIVIDUAL COILS. YOU MUST FIRST REMOVE THE BOLT ON TOP OF THE COIL AND GENTLY TWIST AND PULL UP ON THE COIL WITHOUT RIPPING THE BOOT. UNPLUGGING THE ELECTRICAL CONNECTOR IS NECESSARY ON MOST MODELS. SOME OF THE NEWER MOTORS HAVE A COVER ON THE TOP OF THE ENGINE THAT HIDES THE COILS. PLEASE KEEP ME POSTED. THANKS FOR USING FIX-YA. BEST OF LUCK

SOURCE: 2002 Chevy Tahoe sputters and stalls out while driving.....

Fuel filter. Timing/timing chain. Idle air control valve. Idle sensor. Vacuum leak. Probably one of the above, but the filter is cheapest place to start. Change your air filter too, if you haven't for a while.

Usually that's just a combination of fuel and oil wicking up the threads. Make sure the plugs are torqued properly. Is there any other problem that led to the examination of the plugs?

I have a 2002 chevy tahoe changed fuel pump and filter. it still wont start when you turn the key over it reads empty but we put 6 gallons of gas in it what could be wrong?


Check the fuel pump relay or the fuses. Could also be a filter near the injection rail. You might have a fuel cut off swithc. I don't know where it would be, but your owners manual would tell you. Good luck anyways.

2008 chevy tahoe delayed start


The list of possible causes is long.
You'll have to figure out if it is fuel or ignition related to proceed.
I would check fuel pressure and spark first.
If you can't duplicate the symptom it may be tough to diagnose.

The starter turns over very well on my 2002 Chevy Tahoe but it will not start. It acts like it is not getting any gasoline. Can anyone give me some troubleshooting suggestions?


Check for spark at your plugs first, with the plug out check for fuel in the cylinder. It can be a number if issues but you need to establish if you are getting spark at your plugs.

What part get replaced on a complete tune up on a 2000 chevy tahoe?


I would replace
1. spark plugs. Do not go cheap on the plugs use the proper AC Delco spark plug
2. cap and rotor
3. spark plug wires
4.fuel filter
and then i would have a fuel injection cleaning done . there is not a timing adjustment or air fuel adjustment this is all done by the PCM ( Powertrain Control Module )
