SOURCE: the cilynder #1 and spark

Did you change the spark plug?? Your car (1993) has a distibutor assy, which means it has ignition wires for each plug. How are your wires??cap?? rotor?? Have you ever done ignition tune up?? If the answer is yes and you have already installed new injector and pressure regulator (althoug it still could be a injection issue/ECM or computer, because ECM is what drives the injectors. If the ECM or wiring to #1 injector has an issue, the injector will not fire off and put gas into the cylinder, resulting in a misfire.) Remove #1 injector connector and check to see if you have power/12V on one side of the connector. If you have 12V there, than check the other wire for continuity to the ECM. You will need wiring diagram to find the right wire color at the ECM. That other wire goes into the ECM to the driver which opens and closes the injector depending on your demands as far as gas pedal input. That driver may be bad, causing the injector not to shoot gasoline. Than I would be looking into a engine issue, such as burned valve, or head gasket problem (coolant getting into #1 cylinder, flooding your spark plug). Tough to diagnose over the computer and not looking at it my self. Let me know what you find.

SOURCE: 1998 nissan sentra cranks but wont start parks but no fuel.

Just had the same problem. replaced cap rotor, plugs wires..etc. still would crank no start. i got really angry with this so i went old skool on it, and treated it like my 1975 chevy one ton.  I hammered the gas and cranked it till it sputtered and eventually started. note: by pressing the gas to the floor and cranking will put computer in recovery mode and not let new fuel in to the engine. now it is able to try to burn all the left over fuel sitting in each cylinder. after about 45sec. to a min of cranking she started to come to life again. one other problem did come up. after blowing out all the extra fuel and ****, it did blow my pre-cat o2 sensor. no big deal $45.00 at checker. hope this helps

SOURCE: 1995 Nissan Sentra, The engine light and brake

You could have faulty altenator or short causing the battery to drain. The engine light usually comes on when anything electrical or sensor wise is faulty. Brake light will come on if, low brake fluid, e-brake handle is up.

2004 nissan sentra won't start, battery ok, just keeps turning over


Check for spark on any spark plug wire. If you have a strong blue spark, the ignition system is probably good, so then check for gas-is the fuel pump turning on for 2 seconds with key on, not start? It should and that will put gas up to the engine. If you don't hear the pump turn on briefly to pressurize the line and fuel rail (where the injectors are), you will need to troubleshoot the fuel pump circuit. Check the fuel pump fuse-probably under the hood in a fuse/relay block.

Change the fuel pump and still won't start on a 2002 chevy avalanche


Check for spark to the spark plugs, while cranking the engine. If no spark, you could have a bad ignition module, or a bad crankshaft position sensor. The crank sensor sends a signal to the computer, to start the fuel pump and signals the ignition module to start firing the spark plugs. It also drives the tachometer through the computer (PCM) Powertrain control module. The ignition module can be removed and taken to a parts store to have it tested. The crank position sensor is not as easy to test. Easier to just replace it. Good Luck. But wait, I have seen people replace the fuel pump, checked the fuel pump harness for power, and all was good. However, if the fuel pump does not have a GROUND, it will still not operate. Might want to check that. Have fun.

Nissan Almera 52 plate. not starting when it stalls.


One of the items you can try is to turn on the ignition switch, so the dash board lights come on, and wait 10 seconds before you start the engine. You have an electric fuel pump and it must build up pressure so you have the correct volume of fuel going to the fuel injectors. The fuel from the fuel pump goes to the fuel rail that supplies fuel to the fuel injectors. There is a pressure regulator to keep the fuel at the proper pressure. The excess fuel is then returned to the gas tank. On my 2003 Nissan Sentra SE-R SPEC V, I had similar problems. By waiting this amount of time I have ensured the pressure was up in the fuel delivery system and it was working as designed. I may have a bad check valve which then allows the gas to drain from the fuel rail, but I have not gotten this far yet in my own repair. This has allowed my car to start and not flood out, if it stalls as I had seen before. You may be experiencing the samething.

If your check engine light is on, you may have fouled spark plugs, check these out also, especially if you are seeing cylinder misfire in one or more cylinders.

1996 Nissan Sentra doesn't have sparks


Hi and welcome to FixYa,

Initially, to my understanding, 1995 to 1997 Sentras share the same ECU (except the '97 1.6L). Below ECU pin configuration may be of help.

Additionally, depending on the regional version that you have, the '96 Sentra may be sharing the same electronic ignition with an Altima. If so, this might interest you.

Good luck and Thank you for using FixYa.

1995 DODGE RAM B1500 NO START


You need to use a LED type test light for the injectors or a Bosch style Noid light for the injector. To test the cam/crank sensor signal you either need a scanner to read them or a lab scope to show you a signal. The pickup plate in the dist handles the injector timing, the crank sensor provides a RPM signal. They both feed the computer information for ignition timing. Good fuel pressure, injector activity(Noid), and good spark out of the coil. The coil is what I replace the most of.
