3000ish psi is 200bar I can't recall what it needs to start, 200, 250 or 270 ( i might have said 250psi in previous post, i meant bar, brainfart.)
If you have a friend, get them to crank the car while you do the next test.
Standard disclaimer about not getting body parts stuck in moving engine parts.
Let's see if you're getting injector pulse as part of the starting sequence ie. fuel pressure ok, injectors are firing.
Grab a test light, take the wiring connector off the first injector.
Slap your test light ground lead onto the battery negative post.
Key ON, but not cranking here...
Touch each of terminals on that connector, one will be 12v live with key on, the other is ground.
The ecu pulses the ground on these injectors to fire them.
Once you have located the 12v constant, you're going to want to put your test light ground clamp on the positive battery post, and touch your test lamp probe to the ground pin in that terminal. Hold it there.
Now have your friend crank the engine.
Keep an eye on your test light and see if it starts pulsing.
If it does, great, ecu thinks fuel pressure is ok, and is trying to fire the injectors.
If not, we look into fuel pressure issues.
Either way we learn something and get to move to the next issue.
By the way, did you snapshot your codes, clear them and start from scratch?
What were the new codes generated when you tried to start the car?
Then after giving it a huff off starter fluid and the car actually started running, what were the new codes generated?
