Hello and welcome! My name is ***** ***** I can assist you with your question. So the engine cranks over but does not start? And it does not run on starting fluid? No codes in the computer?
It is very possible! How do you know there is not enougbh spark?
Ok. let me do some digging
Ok, if the engine does have spark but does not run on starting fluid, then yes, the engine is out of time. Ignition timing or valve timing. This could be related to the timing chain (broken or jumped timing chain) or a broken/cracked flex plate/flywheel.
We are not done yet. We are just getting started. I have a lot more ideas.
What is the engine compression at?
That is a good reading. However, that does not mean the engine is in time. The timing chain can still be off a tooth or two and it will still produce good compression readings. Are there any codes in the computer?
Ok, if the crank sensor or cam sensor was bad it usually sets a code. Also, if the cam or crank sensor was bad, the engine wont have spark when cranking.
I completley understand. But it is what it is. If the engine does in fact have spark but it does not run on starting fluid, the engine is either flooded or simply out of time.
YES, you can remove the spark plugs and line up the pistson on each cylinder at TDC. Then remove the valve covers and check to see the position of the valves. With the piston on TDC (going up on exhaust stroke and coming down on the intake stroke, the exhaust valve will close as the intake valve starts to open as the engine is being rotated slowly. This is called valve overlap. Valve overlap should only occur with the piston at TDC.. not before or not after TDC. If it does, then the valve timing is off. Keep in mind, you wont be able to see the valve inside the piston.. but you will be able to see if/when the camshaft lobe is pushing or forcing the valves open when veiwing from the top with the valve cover removed.
