Hi Kathie!

It sounds like you probably have a cracked or disconnected vacuum line going from the engine (intake manifold area) to the transmission modulator valve. This is the only vacuum line that goes to the transmission, so if you can locate it under the vehicle at the tranny, you can trace it back to where it connects to the engine, and also check to make sure it is not leaking or disconnected. If it is bad, you will need to replace it.

If that is not the problem, then the modulator valve itself has probably gone bad and will need to be replaced, but that is an unusual failure.

Kathy, sorry for your troubles, hope this helps you get it straightened out, but if you still have questions or comments, do not hesitate to let us know! And please remember to rate my advice - your rating is my ONLY compensation for providing this assistance!

Thanks!
WildBill

I need a wiring diagram


Here you go.

Starts on page EL-90, diagrams start on EL-92.

Remember, with a vehicle of this age, it may be as simple as the motor brushes are worn down to nothing and you'll have to replace the motor.

92 chevy idles real fast on cold start up, then after run warming up runs fine


Not an uncommon issue for one to idle fast while cold but , 2000 rpms is a little higher than normal. May want to check the engine coolant temperature sensor for proper voltage and the coolant level. Also, check for small vacuum leaks around the throttle body gasket.

You would need a repair book with wiring diagrams to troubleshoot the ignition system. You would need to know if the coil and module are getting power to begin.

Hello i have a 92 nissan 240sx just got car started after installing head gasket car ran great all day other than a small surge under mild throttle, later that night when i went to start the car now i have...


When replacing head gasket you had to disconnect and move spark plug wires and coil wire.Sounds to me if it ran for a little while then died out look for a burned wire by exhaust manifold.Something must of shorted out.Thats why it ran a little while and died.

1993 240 nissan clutch pedal acts like it has no fluid


Check if the slave cylinder is being activated by the operation of the master cylinder (also ensure no fluid leaks are present).
If slave cylinder not moved, you still have a faulty master cylinder or slave cylinder - or the hydraulic system still has air.

If the slave cylinder is operating normally and there is still no return pressure from the clutch pressure plate, you have a faulty pressure plate or throughout lever mechanism.
