1993 300zx Electrical MAYHEM

[300scotties]

I recently became the owner of a beautiful 1993 300zx non turbo. There were no recorded problems on the CarFax report, and the previous owner swore on his life that it ran perfectly (I'm starting to think someone should run him over ). BUT, these past 2 weeks, I've had repeated problems with the engine cutting out at consistently RANDOM times, RPMS, gears, weather, and inclines/declines. i've tried using the product "HEET" to remove any possible air/water pockets in the fuel line and simply, am out of ideas. I'm thinking it's an electrical problem, but like I said : i'm not sure. Please help as soon as you can, for this is my daily freeway driver and I won't feel comfortable driving it to work and school until this problem is fixed.

Sounds like the PTU needs replaced...maybe it never got the recall.

Today i replaced the fuel filter, both air filters, and fianlly got the right PTU on there (the previous owner had put an after market PTU on with a make-shift wiring kit-very poorly done)

Thanks for your advice!
