check your mass air flow sensor . tap on it GENTLY . should start
check for spark from the number one plug wire if no spark then start with the coil
A 2003 Chevy Suburban will crank but not start if it has no spark or fuel. Checking for a clogged fuel filter or fouled spark plugs can help to resolve the problem.
If the car will not start...the spark-plug is bad.
are you getting spark?
Does it have fuel, spark, compression?
make sure its not getting to much fuel and check the timeing/and if the wires are in the right order
You are missing fuel or spark.
if it is cranking but wont start check for spark, fuel, air and compression.
For an engine to start it needs spark to the plugs and fuel. Without both it will not start.
My 86 vette was doing that ,was getting fuel and spark to the distibutor , but had no spark to the fuel injector ,fixed fuse problem , started are away and stayed running
check for spark
