Car belongs to my son and he said it occasionally will run like crap so I pulled codes 0011, 0021 and 0300. Pulled the Vvt solenoids cleaned and checked to make sure they were working. Car still misses terribly. Cleared codes and took it for a drive. Runs like crap until you floor it then it hesitates and surges then will suddenly take off like a bat outta hell. Came back pulled codes 0302. Swapped 2 to 6 went for another drive, same thing. Came back pulled codes 0305. Tried to check fuel pressure but how, I pulled the rear seat and hooked there. Turn key on goes to 50 psi and drops back to zero. Tried to hook into the line there so I could start and see what it does but it just leaks fuel everywhere. Any ideas? Don’t want to just throw parts at it but I will if I have to

What year is this Maxima? Misfires can also be an intake leak! Check your hoses, and even the mating surfaces of the UIM, LIM and intake clamps after/downstream of the MAF....I use an Ole school timing light to watch my ignition events just place the inductive pickup around the coil pack connector pigtail...Then watch each cylinder's ignition signal if it skips a beat there's one cylinder you need to troubleshoot isolate. Swapping coil packs or spark plugs...Good luck!
