Car stalling help

[240sx_in_209]

Hey well i have a problem lately my car has been stalling... when i bought the car it was all good.. no problems never stalled or anything. Well my radiator blew up so i decided to get a aluminum radiator.. well from doing that i thought might as well got a electric fan. Well i ended up getting a ford taurus electric fan. Got a relay wired it all up to my fuel pump. Well i wired the electric fan so when ever its on it would be on high. So after that happen it would die on me... like the battary would die. after that the car would start to stall never driving always when getting to a stop sign. everytime i would do that i would just step on the gas a bit and it would go back to normal. Well yesterday i was driving it and it did it out of nowere. and it keep doing it.. now the car wont idle it would just turn on and then die out, but when its doing it and i step on the gas it feels like its booging out... but when the rpm are high up its fine.. they were telling me because of the fan it might be killing my alternator or it cant keep up the amps.. could this be right.. ill post up a video tomorrow.. thanks...

yup sounds liek the alternator is dying out

well if its the alternator your battery would be dead and the car would not restart after dieing, a few ideas for ya, first when ya wired the fan ito the fuel pump you may have caused the circuit to get less voltage resulting in low fuel pressure, hense the car dies randomly, additionally if you blew the rad a blown head gasket( when it first goes) will cause random rpm issues as well as causing the car to die in some cases, if you wanna check out the fuel issue, first thing get a volt meter and check at the batt poss to neg to see what your voltage is, then check from any good ground to the power wire at the pump if the voltage has dropped as little as .5 volts then you may have a fuel issue, or you could check fuel pressure while having the fan both pluged in and unplugged. if you have any furthur questions or more info to add feel free to hit me up.

fan could be overloading your old a** system. Check the output of your charging system and check the draw on it when that fans running

you should also wire that fan right
