When was the last time you had a tuneup ? Maybe a miss firing spark plug.

30 k ago I put new wires plugs cap and rotor button on. We took on a bout a 100 mile trip 2 Saturday's ago got home late went out next morning to go to town and that's when it started


No check engine light ?

No sir I'm Not sure!!! It won't run. Just turns over fires about 4 cylinders almost like one would do when its out of gas. Check engine light does comes on when you first turn key on when your soppose it check your gauges before you crank it


Does the check engine light go out after vehicle is started or does it stay on ?

Please Forgive me if I mis-lead you its hard for me to put in words on what it does. .. it won't run at all as soon as you let off the switch from start position it stops When you turn key to start it with the starter still in engaged it sounds like 4 of the 8 cylinders fires than than goes back to just turning over with the starter.... never dose it actually run on its on power


Oh ok get the check engine light scanned for codes even if light was on then went off it will store the code in its memory may tell you what the problem is but it sounds like the camshaft sensor just a guess.

Ok thanks for your sopport. Hopefully that'll tell me something I'm about ready to plant flowers in it. For a yard ornament.


Sorry did not answer you right back was night time here and was getting ready to go to bed but that is funny about the yard ornament. LOL
