Hello, I have a problem with my 1996 Nissan Sentra. I had the car without a battery for about two months as I was not using it. Now that I'm testing it, it cranks but it doesn't turn over. I've replaced spark plugs, spark plug wires, new battery but it won't turn over. It turned over twice before dying right away. I have also sprayed starter fluid to see if it's the gas pump and it still does not turn over. I've tested the alternator with a multimeter and it's reading 12.8V. I'm wondering what it could be. Thanks in advance.
At the moment, I've used a inline spark plug tester and the tester lights up.
Here's an update so far on what I've done.
I've replaced the distributor
I've replaced the battery
I've replaced the fuel filter
I've replaced the gas pump
I also checked the alternator again, it's running at 12.6 Volts stable.
The car continues to crank but it does not turn over and start. I'm not really sure where to go from here, hoping someone can chime in. Thanks.
Another update
I checked the fuel injectors and the first one and the third one have a lot of gunk and deposits on them, the second and fourth one seem okay. I tried a fuel injector test by hooking up wires to it and seeing if they spray, almost all of them barely spray and some click and do not spray at all. I also disconnected a fuel injector and it continues to crank but does not start. Could it be a bad fuel injector?
Another thing is that since it has a 14 pin Nissan obd port, I went out and bought a 14 pin Nissan obd and hooked it up to my computer and used ECUTalk software. I was looking at the RPM, INJECTOR, TIMING, AAC, BATTERY, THROTTLE, 02 SENSOR, STARTER and PW/ST SIGNAL. All the gauges except PW/ST SIGNAL were working well, the PW/ST SIGNAL gauge did not respond at all. I'm not getting any codes either.
Does anyone know what an PW/ST SIGNAL is and what it does? Could it be the cause of the problem or is it the fuel injectors? What else should I look with the scanner?
Thanks.
You will need working-as-they-should fuel-injectors, otherwise the car will never run well...
So start with getting all 4 professionally cleaned and tested or insert new ones (at a price).
Bad injectors will kill your engine on the long run (oil dilution/washing away).
