That thing has barely any compression....... Sounds VERY VERY weak! Sounds like it has low compression on 3cyl with none on the other 3

I made a quick video showing how even the compression sounds on my motor. You can hear in your video that it is very uneven. Do a compression check and report back. Shouldn't be lower than 128psi and each cyl should all be within 14 PSI of each other.

No not sure at all. i'm sure it runs on the diag port but not sure if it runs while I'm cranking.
Devin may be onto something with compression, it should be checked, but it doesn't sound like you have lost all compression IMO I would think it would still fire at least a little. Spray some starting fluid or brake cleaner into a vacuum port and see if it fires up momentarily.
Did that a long time ago. Its correct.jonahs_supra;1730517 said:

Hey, if I don't have proper compression, no worries, I wanna do this right. No rush. These cars need to be respected and done right.
I also just notice the throttle going back and forth. Stop doing that. To get rid of your flooding that has compounded the problem, hold your accelerator pedal to the floor while cranking. This will take 15-20 seconds. Then let the starter rest.
updates? my 92 is doing this too. everything is EXACTLY like yours. timing is correct. cps marks are lined up. #1 piston is at tdc and crank is pointing at 0*. Did a compression test on all 6 and all roughly 95psi. i would think that its that low because my block was bored out to 40 over, probe pistons and rings gaped to (top ring).018, (second ring) .019, and (oil rings).013. Updates and thoughts would be great.
