I've been having this issue where the car cranks for 30 seconds to a minute before finally starting. Once I can get it going it'll run fine and I can even start it back up right away within a couple hours of turning it off.
New fuel pump, fuel & air filters, spark plugs
Fuel pressure is 35psi when running/in accessory mode
I'm pretty sure it's running rich, I've also cleaned the MAF sensor but that didn't seem to fix it.
