I was actually driving back from the gas station, the car had half a tank . Before the hill I was crusing at about 15 mph never passed 25.the car was running fine 15 min into the ride, I pulled up to a stop and the made a left into the hill. The cars didn't even fully enter the hill before it died(about 45 degree climb).the car studdered and died.

I have a set of (6) fuel injectors for a 78 280Z, I used about a month in very good shape, for sale for $190.00 plus shipping, I went to SU'S. Just let me know if you are interested, they are in the original boxes ready to be shipped. Mark designplus@bellsouth.net

Also have a new fuel pressure regulator for $80.00

Anthony, I'm guessing the car died when you hit at least the 2/3 point in the throttle. That's where the throttle position sensor would have signaled the ECU to deliver "full throttle enrichment." I suspect your problem is a mixture problem, and that's where you saw it. Maybe you're running too rich. I'm just guessing, of course. There could be any number of causes for having the wrong mixture.
