    97 Silverado 5.7 2wd, cranks with no start. Replaced cap, rotor, plugs, wires, coil, ignition control module, crankshaft position sensor and fuel filter. Still cranks but no start. Getting fuel and spark. I’m at a loss. Have been told to check grounds, steering column and even been told it’s the fuel pressure regulator. Any ideas as to what else it cold be? It has no codes. Was driven where it is at and shut off. Went to leave two days later and got the cranks but no spark. Oh, it surged/skipped right before it got home. Thanks

    Ok… a little confusing on your description..

    Replaced cap, rotor, plugs, wires, coil, ignition control module, crankshaft position sensor and fuel filter. Still cranks but no start. Getting fuel and spark.

    Was driven where it is at and shut off. Went to leave two days later and got the cranks but no spark.

    I have to assume you first had no spark and then after the repairs you again had spark.

    First question, How did you confirm proper fuel ?
    Did you attach a pressure gauge to the fuel rail?

    Have you confirmed timing and #1 TDC are correct?
    Also might be a good idea to do a compression test and perhaps a leak down test.
