slow response, now does not start
 

Wondering if anyone has experience this, 91 240 all stock. Was hard to start and when it did it didn't have any throttle response. You could floor it and it would rev up really slow. We changed the fuel filter, plugs, wires, cap, and rotor. Still the same now it won't start. Has compression, spark, and fuel pressure. Removed the fuel rail from the intake and the injectors aren't squirting fuel. Any ideas? THanks

oh and does any one have a 240sx wiring guide. or does any one know where the cam sensor is on a 91 240sx

mine did this....

and what did you do to get it back to life?

mine did too..still working on it.

Check grounds and ECU.

chekc if your is dist is aligned properly and if the voltage from the maf is within spec.

If your injectors are not getting fuel I would start with checking
the fuel pressure regulator, then, I would check my fuel pump.
then I would check injectors for pulse with a noid lite.
