    2000 K2500 4x4 ext cab a/t 454 cid
    Been driving the truck without any problems. I leave work, it starts right up as usual. Stopped to get bait for 5 minutes, came out and it would not start. It just cranked over. Cranked it so much battery went low. Got it towed home, but haven't any clue what to check. I did replace the fuel pump 3 months ago and I can hear it cycle when I turn the key. Any ideas? I am supposed to go to a funeral tomorrow out of town. Please help!

    You need fuel and you need spark.

    Get a can of ether (starting fluid) and spray a little into the throttle body. If it starts, your problem is fuel delivery.

    If it doesn't start, suspect problems with the spark.

    This is a Vortec fuel injection. Can the ignition module be tested?

    Ok, I checked the schrader valve on the fi rail and had lots of fuel pressure. I changed the battery out because it was old and low. It cranks over fast then slows to a point where it sounds like something is hitting. Once past that point it cranks over fast again. Does that make sense? I am going to check for spark at the plugs, but after that I dont know where to go. Any more ideas? I did buy some starting fluid, maybe I'll try that too.

    Sounds like spark....normally an issue like this would be ignition. If you don't have spark at the plug you'll have to check your modules and fuses....I am not skilled on these newer trucks....I work on classics. lol. Hope you are able to locate the issues quickly.

    Ok, update: I checked the oil level to see if it had fuel in it, it was ok. I removed the hose on the throttle body and sprayed starting fluid in it. Still would not start. I pulled the first plug on the Lh bank and cranked it over. It showed spark. Now I am really lost! Where do I go from here?

    Has your Check Engine Light come on? I would check to see if the system is throwing any codes.

    Would a stuck EGR valve do this?

    Is there a way to check codes without a scanner? I dont have access to one.

    local auto parts store willl be able to read them for you...check engine light on?

    just because fuel came out of the valve on the fuel rail, it does not mean that you have the needed 50+ PSI being delivered. It is not possible to tell just by looking the difference between 45 psi and 60psi.

    Let me go back to the fuel pressure. I used a gauge to find 52 psi for fuel pressure. Also, I cannot get the truck to a local parts store to have codes read. They wont rent them either because," they always come back damaged". I dont know anyone who has a scanner either. If it is getting fuel and has fire, why wont it start?

    Also I know the check engine light was on because it is on. I have a EGR code and rear O2 code from earlier.

    When your testing using the spray can of Starting Fluid, you spray it into the mouth of the throttle body while someone is cranking the engine.

    Yeah, did that too.

    What is the best way to check that the injectors are working without a noid light or removing the upper intake to get to an injector plug?
  15. RayVoy

    If the injectors are your problem, spraying the starting fluid into the mouth of the throttle body should have started the truck.

    If the truck does not start, and run for 2 secs, when starting fluid is sprayed into the throttle body, fuel delivery is not your problem.

    You say you have spark, I do not know what else to suggest.

    I am beginning to wonder if there is a timing issue? I pulled the plug wire off the first plug on the Lh side, and cranked it over a few times. When I pulled the plug it was dry. If the injectors were working, it should be wet. My main concern now is when I crank it over, it stops after a few turns
    as if something is hitting, then it cranks fast for a few more turns and stops again. Any more ideas?

    After all the problems I had, I decided to replace the cap and rotor. Now the truck will start and run, but it has a bad miss. I am guessing a bad wire or I didn't get the cap down tight enough. Was afraid to over tighten and crack. I know the wires are on right as I double checked before reinstalling the coil.
