I'm about to buy a 350z for 4k there is things wrong might need a new ecu, here is what he said
"The current status of the car is that it will start but won't drive. The ECU which was I had flashed for a bunch of parts I've since removed (larger injectors) is either bad or needs to be reflashed by a dealer. I attempted to reset it myself but no success. Car is locked to idling below 3500RPM. I don't know if this is ECU related or if I disconnected some sensor that I'm unaware of. Also, the alarm system that I tried to remove will trigger as soon as I connect the battery."
what should I do to fix these issues?

 

Welcome, but that's a helluva way to introduce yourself to this board. I'd simply advise you to move on and look for another Z33 that hasn't been so badly neglected. It sounds like the car is in limp mode, and you are so desperate to effectively repair it that you're willing to go onto an internet board with the hope any of us can magically help you.

This repair won't be easy or cheap and odds are, you'll find plenty more wrong with this Z as you go through it. No if and or BUTS- just walk away and learn from the experience...

 

You'd be krazie to buy it.

 

I'd run and don't look back!

 

No, DON'T buy this car, it's not worth the headache or your hard earned money.

 

I agree with all that's been said above. There'd be more trouble than reason in buyint this car.
