Question about 1984 Nissan 300ZX

1 Answer

Initial Idle problem with 1984 300zx turbo automatic

Here fuel pump come on , starts on 2nd or 3rd try. I would describe it as a weak idle with low rpm that feels like it's going to shut down. Car will not take gas during this weak low rpm period, makes it choke up. This goes on for 3 to 5 minutes and gradually the idle evens off nicely and then I can drive off with ideal acceleration as if there is no problem. This doesn't get worse, it's always the same. I did replace plugs, wires, distributor, battery and starter. I can take this car anywhere once it's warmed up and as long as I don't leave it standing till it cools down it will start fine. Diagnostic tests did not reveal any problem so far. All fluid levels are fine, car has only 67000. miles. All recalls were done prior to my owning the car and it has not been abused. No rust since it is a west coast car. Please offer your opinions.

Will not idle


I suspect that your fuel system is faulty. Check for a clogged fuel filter, or if your fuel pump don't run at all, replace the "fuel pump relay". Sometimes your fuel pump will run, but be too weak to hold pressure, which will let your car idle somewhat, but be too weak to run the engine at speed or under load.

Hard to start, dies, missing out, hesitation, low rpm take off missing out


Fuel filter clogged, weak or faulty fuel pump. Have fuel pressure checked, if its ok, then check igniton coil or module.

Very likely a low fuel pressure problem. Have you changed the fuel filter? Check the fuel pressure against vehicle spec's while running at idle and again at about 3000 RPM. Also check pressure with key on/engine off. If you lose pressure between idle and higher RPM's you probably have a weak fuel pump. Same goes for if you lose pressure after initial key on/engine off. You could also have a problem with a weak ignition coil, spark plug wires or spark plugs but not as likely.

Having a problem with my 1994 eagle talon. no


shake at idle means u have a cylinder misfire or low commpression, here are causes of misfires most commonly seen.

The most common misfire causes on the cars I've worked on have been:
  1. Spark plugs
  2. Spark plug wires
  3. Ignition coil
  4. Fuel injector
  5. Wiring to fuel injector
  6. Timing Belt
  7. Vacuum leak or stuck open EGR
  8. Contaminated fuel or bad fuel pump
  9. Weak compression
  10. Blown head gasket

Doesn't start on first turn, by 2nd or 3rd starts. Idles rough.


Battery should be around 12V the alternator puts out 14V. Sounds like a fuel problem, leaking injectors or injector's O-rings. Weak or faulty fuel pump, clogged fuel filter, faulty fuel regulator. Try this, when starting the car while cold. Put the key all the way to the ON position, wait five to ten seconds then crank the car to start. It should start the first time the longer you give it the more fuel pressure there will be to start the car.
