Ok guys, I just picked up an 1989 Nissan 240SX Fastback, auto. Well its just gunna be a play around car and hey for $600 you can't beat that! Plus I want it as a daily driver to keep the miles off of my Honda, yes I know you guys hate hondas!

Ok well I put a new battery, fuel pump, rotor, dist cap, wires, plugs, oil filter, and changed the oil, and it runs completely fine, except for one thing, when you turn left it stalls out, what could this be? It doesn't stall out at red lights or turning right, just left!

Any ideas, I want this fixed, some people said something about powersteering and some said timing chain, I have no clue, please give input, thanks guyse!

sounds like a wiring problem since it seems to be related to a specific movement of your car. Check you engine control harness for wear and loosen and resecure your grounds.

my guess would be something with the powersteering. Your rpm's should drop a little bit when turning the steering wheel, but not enough to make the car die...I suspect the ps pump.

but it doesnt do it when turning right. which would cause the same amount of pressure on the system and draw the same amount of load on the engine. There is only one idle compensation switch in the power steering to compensate for the load. it is a pressure switch usually located at the pump. and that is only if the car came with that option.

Yes, it doesn't do it turning the the right, just the left, and if you aren't turning left real sharp it will stall a lil, but give it gas and it will kick back in, but a sharp left it will cut all the way off, it will crank right back up, but this is the only thing keeping me from driving this car, otherwise it drives great!

Wheere is the main wiring harness, I will check that and see if it is loose or not. And about the powersteering, I can't really tell if it has it or not, I am almost positive that it does, but I don't see a resovoir(sp) anywhere to check power steering fluid, so I don't know, anymore suggestions?

resivoir would be on the passenger fender well . black cyl with hoses attached to it. The main engine harness is the harness that runs all over the engine to its different components.

How would I go about checking the harnesses, just kinda jiggle em around, or what? Ok, I checked that, It didn't say power steering, I figured thats what it had to be, just thought it would be on the driver side, and it had plenty of fluid, please give more details on how to check wires, hopefully this is what it is!

Oh and thanks for the help NISTECH

just look them over real good for and rubbing through. especially where it runs along the valve cover at the rear. should of taken some paint off the valve cover by now. make sure the wires havent worn through at that point. also where the grounds connect at the front of the intake manifold. make sure those are clean and secure. wiggle them a bit slowly move them dont use quick jerks. see if it causes any stumbles in idle while your doing it.

Ok, NISTECH, I ran into another problem, I was checking all the wires, and all seemed fine, except when the plugs on the fuel injectors were touched just a little, well I turned the car off, removed them and put them back on, in the correct order, and the car will not start, the fuel pump is still running, is this where my problem in the first place could have been, what happed? Thanks

unplug the injectors and inspect the connections for a green crusty substance. if you have that, the best way to fix it is to replace all the injector connectors. splice them in to the original harness. Then clean your injector terminals with battery cleaner and a pocket screw driver to scrape away the corrosion on the terminals. But if this is not budget friendly and you wanna temp fix it till you can do it right. spary some of the battery cleaner in the connection of the connector, do you best to brush it some what clean. take a scribe and squeez the female connector together slightly where it splits on one side. this will make it fit tighter on the terminals.

Sounds like you need to adjust the float on your carburator. (I'm just kidding). I'd bet those injectors and wires are at fault.

Ok, so should autozone or any parts place have just the connectors, or will I need new injectors? Also, any idea how much they are? I just want the car to be drivable, then I will start rebuilding. Hopefully this was the stalling problem too, I am gunna check and make sure they are getting power, I just need to know where to get the connectors from, thanks guys!

nissan dealer is sure to have the pig tail connectors you just soilder them in and seal them up. not sure if an auto parts store will have the connectors or not.

Check the resistance of the wires @ the injector. If you can wiggle them and the problem goes away, then obviously it's a terminal that needs to be cleaned and/or replaced. My advice is worthless, because I don't know how your car runs, it could be a hundred different things, even a fuse! Just remember: Fuel, Air, Fire.......................vroom
