1985 Nissan 200sx

99k original miles New battery, new motor parts, new starter, new injectors, new fuel pump i bought it and put 6k into it. The motor looks amazing but for some reason it wont stay running and idk what to do…I’ve spent so much money I want some money first. Rims comes with the original I have 2 sets of tires. 4000 or best offer Car has never been in a wreck clean title once it’s restored it’s worth 15k All it needs is to get the motor running fully as it stalls right now. A right taillight as this one is cracked a bit and to seal the back little window and finally some body work to finalize it all. Once those 4 are done it’s beautiful again! I can’t even solve step 1 that’s why I can’t keep it I’m in college, I’m working full time and I have other side business things I’m working on. Come look at it and make an offer I wanna see it complete I just can’t figure out why it won’t stay running.
