Question about Chevrolet 1500
When an engine stops running it is either lacking spark (at the right time), fuel, or compression. When in your situation, I first check for spark by removing a plug wire and (while the engine is cranking over), watching for an ark (or spark). The spark should be blue/white not yellow/orange.
If no spark, repost your findings here. There are a few items of concern in the distributer that may need to be checked such as the distributer cap, ignition coil, rotor, and the ignition module. Also locate your pickup coil inside the distributer (beneath the rotor) and check for broken wires. Also inspect the reluctor wheel for cracks in the magnetic portion of the star shaped area.
If you have spark, use a timing light and check to see if it is firing at the correct time. See your tune up data for correct specs on ignition timing. (I think it may be at Top Dead Center.)
If you have Good Spark, and it is in time, try priming the engine by adding a small splash of fuel down the throttle body/carb/intake system.
If adding fuel causes the engine to fire and actually run ok for a short period of time, then look deeper into the fuel delivery system. Start by checking the fuel pressure, fuel pump, fuel filter, regulator, pump fuse /relay etc.
If after adding fuel it still does not start, check the cylinder compression to rule out any more complex mechanical problems.
Please repost your findings for a more precise diagnosis.
Please let me know if this helps amd Good Luck!!
