99' Base 5 speed Cranks / No start / No codes / New CPS

[Chi-Town]

Ok, got up early before the heat started and did some basic diag.

Fuel pressure while cranking 34-36 psi

Showed spark on rear cylinder LH side

Pulled the plug, wet with fuel

Tried a squirt of starting fluid no change. (open or closed throttle)

No codes in any Modules

Cranks smooth, no noise

Does anyone have a video of an M96 cranking with a broken timing chain?
I'm thinking there would be a code stored if it broke even if it's only cranking?

I have a spare 2.7 but I was hoping to avoid the engine swap.

You say it cranks smooth no noise.
you could do a compression check on a few or all cylinders to verify correct valve action. If you have a broken timing chain I would think a piston would have hit a valve by now.
You mentioned oil leaking at the spark plug tubes. How bad? is there any chance that the oil is grounding your plugs out so your not getting spark in the cylinders?
