1999 Sentra Start/No Start Dilemma

[buckhardy151]

Daughter moved car, then tried to start and boom, won't start. checked for fire-good. checked fuel pump fuse, pump, pressure-all good. changed the fuel filter and car fired right up! While everyone was cheering, the guy behind the wheel turned ignition off after bout 45 seconds of idle. tried to start it up again. No go. Next morning-started, idled very rough, and only ran long enough to move it bout 20 feet. boom! no start again!!

Does it smell like fuel or anything when you're attempting to start it? I might move this thread to the Nissan Online Mechanic section if you don't get a good answer soon.

Seems like there may be a slight gas smell, but it could just be from accessing the fuel tank to get a look at the pump. I held accelerator to floor yesterday while cranking to see what happened. Seemed to lope a couple of times as if trying to start, but, still no start. checked for fuel leaks, and none found. Could it be the crankshaft sensor causing this?

Usually when those go, it doesn't start (or even attempt to start) at all. Have you tried plugging in an OBDII scanner to see what codes its giving you?

[buckhardy151]

No codes, except in snapshot, and that one was I believe 0p04 or something like that. I wasnt the one who ran it. I know there was a P and the rest were 0's and one 4. Might be our fault for no codes due to checking fuses.

Keep flooring it and cranking - even tho' you might have a fuel-injected engine the symptoms are similar to a flooded carburetor engine. Get a jump from another car so you don't run down your battery.

Here's something to also try: taken from another forum -

All that was needed to fix my car was to pull the fuel pump amp out of the socket, start the car it ran for about 15-20 sec before shutting off, the put the amp back in. Started the car again and has been running and starting perfectly fine since.

[buckhardy151]

Hmmmm. I'll try those, Faja

New plugs, rotor, and cap. Had to change oil because it was dumping gas into oil. New plugs wet with gas, but still no start! IDEAS?

Have you pulled out every single fuse and looked? i had a problem like this in my NX2000 the car would crank but not start i did a quick check of fuses while they were in the fuse holders and i saw no signs of a bad fuse, but when i pulled out the fuses one of the fuses was blown on an area that cannot have been seen by just looking at it from the top-side...
