Is this an OPTI issue?

Hey you guys just wondering if you think this is an opti issue before I tear it apart. This is OPTI #7 (Minion)

I put the car in park after a drive and it just dies, no pop or backfire. No codes it just cranks, I used a spare ICM and coil just to see if it was one or the other no issues there. Fuel pump is working with excellent psi to the injectors, has spark but it sounds dry when cranking.

By the way it is my 5 year wedding anniversary and 5 years ago I had some issues with it also before my wedding. I think the car is cursed I'd say, CURSED!

did you check to see if you are actually getting spark to the plugs? possibly check the harness to the opti...

Do u have a check engine light?

No codes, No SES, I am getting spark, used my spare harness to make sure.

Check for an injector pulse. check your vats system, make sure the wire to the tumbler didnt break when you put in park.

The VATS is turned off. Where would this wire for the tumbler be located?

What is the fuel pressure at the rail when you key on, and then again when you crank?

the wire is in the column, but if vats is turned off that wouldnt matter.

Well I rechecked the fuel pressure at the rail and I have zero psi on prime or cranking. But the fuel pump itself is primimg.
I think I am going to re-tune it.

Wait wait wait... if ur getting no fuel pressure, u need to address why u are at 0. Sounds like a leak or blockage. Just because u hear the fp does not mean it is functioning properly.

If u really think it is somethimg tune related... do u happen to have another pcm that u can throw in just to see what happens when key on or cranking?
