need to step on the gas while start it up in the morning :(

[hangout]

on my 97 Maxima, while I start up the car in the morning, I need to give it a little gas as soon as it fire up. but just for a few seconds. otherwise, no way can just start it up like normal. RPM will drop down to zero !same thing happened on my se-r before,

anyone had the same experience before? how did you fix it?

it's not a big big deal that I step on the gas to start it up. but just wanna learn this then I know how to deal with it..

Thanks

If you don't have a problem once the engine has started, you may have an internal fuel leak somewhere causing the fuel to bleed back into the tank after engine shut down. You have to perform a leak down test below:

Fuel Leak Down Test (4th Gen Maxima/96-99 I30))1. Verify that there is no external fuel leak in the system.2. Depressurize and empty the fuel line by pulling out the fuel pump fuse while the engine is running. Once the engine dies, crank at least once more to ensure the line is empty. CAUTION: ENSURE THE FUEL LINE IS EMPTY BEFORE BREAKING THE LINE – FIRE HAZARD. 3. Tee in a fuel pressure gauge between the fuel filter (besides brake booster on firewall) and the fuel rail (A fuel pressure gauge kit may cost @ $20 or can be borrowed for free from Autozone). 4. Install fuel pump fuse and turn Ignition Switch to ON position for a few seconds to prime the fuel line. Verify pump is running (humming can be heard behind the rear seat, pax side. Turn Ignition to OFF.5. For the actual leak down test, turn Ignition to ON position (do not start the car). The fuel pump should run for @ 5 seconds then shuts down automatically. With the pump running, fuel pressure should read 43 PSI. Once the fuel pump shuts down, if the pressure gauge drops rapidly or more then 10 PSI in 10 seconds, there is a leak somewhere in the system which needs to be isolated.Note: With engine running (vacuum on), fuel pressure is regulated to 34 PSI.6. Repeat the process (Pump ON) but pinch off the fuel line between the fuel filter and the pressure gauge as soon as it reaches normal pressure. If it continues to leak down when pump shuts off, the fuel pump Check Valve is good and the problem lies in the fuel rail, Fuel Pressure Regulator (FFR) or even Fuel Injectors. If it didn’t leak down, the fuel pump Check Valve is bad.7. If leak down persisted, problem may be on the FFR or fuel injectors. Repeat the process (pump ON) but this time pinch off the return line. If it still leaks down, repeat the test but this time, pinch both lines. If it still leaks down, the fuel injectors are leaking and must be repaired/replaced immediately (may cause hydrolock). If there is no leak down when the return line was pinched, the FFR is leaking and must be replaced.

Good luck.

BTW, is the CEL on? If so, go to Autozone and have a free scan and get a printout of the fault code, if any. The MAF sensor could also be a problem (may not necessarily throw a code when dirty or has partial internal failure).

One of the forum members have suggested that you may have a Upper Plenum Gasket leak, causing the engine to stall when cold. The leak is sealed when the engine warms up.

I see a tiny leaking spot on the ground.. I will go check..

this happened to my car, my buddies max, and my buddies altima. it was the fuel pressure regulator

FUEL PRESURE REGULATOR OR CAT IS CLOGED

is it a big deal to fix it?or I can just leave it like that,,coz I will sell the car after 8-9 months.

Would be better to replace it, @ $80. Should be the same for 95-99 Max/96-99 I30. Make sure you have a new o-ring that goes with it.
