Hey everyone I am new and I searched a little but cannot find a single drop of help on my situation.

So I have 01 LX Manual 4 Door 128k
The car recently started to crank and not start out of nowhere. Push starts perfectly. No CELs
So I changed the fuel pump, crank and cam sensors and have checked for compression and spark (all good)

When cranking it sounds like a healthy good crank also.

I am extremely confused. She runs great after a push start, but I have to do that every single time I start the car now.
Again; compression, spark, fuel pressure and battery are all good and she runs really great when started

Thank you in advance.

Immobilizer system working as it should? Is the green key light flashing? Electrical portion of the ignition switch OK? Bad main fuel relay bad (behind the glove box)?

You need compression, spark and fuel as you say.

Yes Immobilizer is good .. I was suspicious about a main relay but I ruled it out due to the fuel pump engaging when key is on and car runs fine when push started. I could be wrong though?
