SOURCE: 1999 Chevy tahoe will not start
check the crank sensor. no signal from the crank sensor causes a no spark condition. best way to check is to put a scanner on and check for rpms.
the crank sensor is differnt from the cam sensor

test and see if you have spark and fuel preasure, you may have bad feul pump, common problem is the fuel pump goes bad, but check before replacing.

What you need to do is check for fuel pressure.The pressure should be 60-66 for central sequential fuel injection and 56-62 for sequential fuel injection.If pressure is good then check for spark at the spark plugs.If you don`t have a way to check for fuel pressure then tap on the gas tank bottom with your foot or hammer while someone is turning the key and trying to start the vehicle.If it starts then replace the fuel pump.If this is good then check coil and ignition module if you are not getting spark.Hope this helps.Good luck.
