ok guys i used to have a 240sx, traded it for this 1988 rx7 its a na but the last owner added a custom made turbo, coilovers, etc etc. now to the fuel pump it has a walbro 225 fuel pump and i have no idea what kind of injectors it has. dosent have apex seals. so i would drive this car daily drove fine sometimes it would stall when i accelerate hard. i would turn the ignition of then wait like 5 mins and it would start back up again. checked the oil, collant everything is fine.about 1 month ago it wont start at all now, so i changed the whole ignition switch and key. cause i thought thats why it wont start now but thats not the problem. i am very new to these cars and i would really be happy if yall can help. thank you guys.

 

The rotors have to have apex seals as the seals cause there to be compression in the rotor housing. Without the proper compression the car would not start or run properly.

 

The reason it doesn't start is the fact that it has no apex seals. You need to get some and at least put them in the glove box. They are pretty important to have!
