Car sitting in driveway NEED HELP!!!

[GMWR07]

I have a 89' 240sx with a KA24E and it starts up fine, drives fine when its cold... and now everything messes up. When its really hot outside or the car is fully warmed up for a lil bit... or both, the car will cut back under full throttle and then tottaly die down to a stop. I have changed the plugs, wires, air filter, and cleaned the MAF sensor and still does it. any help would be greatly appreciated thanks!

Please does anybody have any ideas on what it can be???? could the fuel pump be going out?

if it cuts out under full throttle sounds like a fuel problem. You would be able to hear if the fuel pump is going out, usually makes a wicked buzzing sound behind the passenger, if you lay the seat down while driving you will be better able to hear it, could also be the fpr, or faulty injectors. Is it only under full throttle or always after warm. There are two sensors behind the head, I think, not sure that one of them is designed to help the car warm up in cold climates, that may be faulty, this is just a shot in the dark don't go crazy with it.

I had no idea how important ground wires where till i hade a similar prob, turned out to be a ground wire by my injectors (Also on the KA24E)

yea make sure you get a good fuel pump and not a cheap one

well... i say test the fuel pump first

but from what you are saying..

check your hoses, the ones that connect to your cold air intake.. happened to a friend of mine, his was slit and it shut dead whenever
