2000 chevy 6.0 starting problems

Check the fuel pressure at the engine and plugs for spark (ignition module).

Chevy 5.0-5.7-7.4 all the same 1-8-4-3-6-5-7-2

Try spraying starting fluid into the intake. Remove the air filter to do this. If it starts for a few seconds then you have a fuel delivery problem. If it does not, then you have an electrical problem with the ignition. there are 3 things needed for an engine to run if it turns over. Air, Gas, Spark (fire). No air filter solved the easy air issue. Add starting fluid answers the fuel issue. Only leaves spark after that.

Look at the keyswitch, I had one that went bad, the starter would still crank but the ECM was not turning on

firing order for 5.7 v8 is 1-8-4-3-6-5-7-2 mostly all of the chevy v8s are the same firing order. the rotor button in distributer turns clockwise, the cylinder numbers are 1-3-5-7 on drivers side, 2-4-6-8 is on passengers side. To get started get your distrutor cap[new one] look on the top you will see a #1that's where you begin you must know if if rotates clockwise or counter clockwise start in that direction then follow the firing order and cylinder line up. good-day!! if cap is not marked, just pull out #1 plug, put a straw or similar in plug hole on top of piston. turn engine over by crank in front of vehicle with a wrench, when the piston comes to the very top just before it starts going down. this is tdc. and rotor button should be pointing to #1 wire on dist, cap. follow from there. good-day !!

Check to make sure that the grounds are good on the engine...the scanner error could be that...and does the service engine light come on when you turn the key to run position? If not, I would take a close look at the PCM.

ARE YOU SURE YOUR NOT JUST HEARING THE FUEL PUMP RUN? IF YOU HAVE RULED OUT THE PUMP TRY CHECKING YOU VENT TUBE OFF PF THE FILLER TUBE FOR BLOCKAGES.

Have you checked the codes?
Mine was a faulty coil.... Twice. I made a heat shield for the second one.

sounds like tbi has gone out on it thats what happend to my 88 silverado
