Is there anything anyone thinks I can check?? If it helps any I can post a video of me cranking it. One thing I notice when it’s cranking is it sounds like it’s misfiring and the injectors on my intake manifold have been leaking slightly now (wasn’t doing this before)

The car need a manifold pressure drop detected to start. look at manifood pressure when ignition on it should bead 14 psi or 1 bar or 100kpa, when cranking this should drop. if itdoesnt car wont start, if map sensor manifold pressure is bad or not stock it wont start.


check the di computer on side of engine has all three mount bolts in and tight or won't start or run or run badly.


Im assuming your runnog stock tune and engine jas stock injectors and map sensor fitted.


Also try unpligging the Mass air flow sensor this is the on on intake near air filter ( not the map sensor on intake manifold) with maf sensor unplugged see if engine starts. unplugging tgis sensor forces the ecu into a very basic limp mode.
