Question about 2003 Chevrolet Tahoe
I have fuel and i have spark.
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.

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

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.
