Are you using a cell phone to access this site. If so; that might be the reason you didn't see all the info in my sig line.

Does anyone else see a problem with adding a few drops oil into the cylinders from the spark plug hole? Especially if it can be applied to the higher side. The thinner oil the better.
Iíve used that to determine if the compression loss was rings or valves. If itís the rings, a teaspoon of oil in the spark plug hole will produce higher compression. If it is the valves it will make no difference at all.

I have tried open closed and partial. Sometimes she will act like she wants to pop but then she just wont.

In the old days it was spark, compression, and gas. If it had all three and it was timed close; it should start. Now there are sensors and things routed through signal flashers and other causes which might prevent it from starting.

I like the new technology when it works right but I like the old tech for simplicity. Less things to go wrong and easier to troubleshoot with the old.

Just to make sure. When you are running the compression test, are you hold the throttle full open? I saw visionJohnny alude to this, but I wasn't sure by your answer if you were holding it open while trying to start it, or while running the test? If the butterflies aren't all the way open during the test then you are restricting the flow.

I had it closed for compression testing so may try open. I gained a little (10psi) on the rear adding oil but none on the front. starting to look like some sort of valve issue. Or could be a timing/ sensor issue? not sure

Sounds like you would really benefit from one of the bore snakes.

10psi difference is negligible.
If the throttle valves aren’t open then you will get a very low compression reading.
I’m betting that the compression is fine and that it is more a fuel or electrical issue/ not mechanical

I'm inclined to agree and in fact said so earlier in this thread but we generally still need verification which is what these tools do.
