I am sorry for the long wait
so this engine will physically crank over and not fire up ?
will the engine run on starting fluid ?
compression is over 125 on all 6 cylinders and you are 100 % sure the distributor is up on TDC correctly ?
if so did this problem happen out of the blue one day where it just didnt start one morning or where you driving it and it shut off on you ?
Double-check the firing order.
It should be clockwise 165432
Did you check it twice or did you have someone else check it twice?
The only thing left is, how are you finding tdc of the #1 piston? If you are relying on the mark on the damper, perhaps the damper slipped and the mark is wrong. I would suggest you double-check that. remove the #1 spark plug and stick a plastic coffee stirrer into the hole and feel for the top of the piston as you turn the crank by hand. Feel as the piston comes up, pauses then begins to go back down. now, go back exactly 1/2 way in between that pause. That is true tdc. Now, look at the mark. Is it on zero? If not, make your own mark.
Ok, next check for a spark from each individual spark plug wire. About the only thing left is the spark plugs. What are they gapped at, did they smell like gasoline the one time you had them out? Did you put new spark plugs in? Do you still have the old spark plugs?
Hi there, New expert here. I have a question, the crank sensor, did you replace or check it?
