    once again thanks for your help. i tried the spark test and indeed i do have a spark. spark plugs are in good condition. tried adding gas, still nothing. maybe its clogged fuel injectors? if so, is it something i could check or fix myself? same question for the fuel pump?

    thanks for your help, i got frustrated and took it to the dealership to see if it was covered by the warranty. they said somehow there was a problem with the headgasket and there was coolant where it wasnt sposed to be. they sent the engine out to get looke at/fixed. and they are going to cover it! anywho, thanks again for your help.

Always verify the easy to do, First using a small diameter phillips head screw driver, remove a spark plug wire and put the screwdriver up inside of the metal contact where the plug normally would make its connection. Place the screw driver around an inch away from the valve cover or any other ground. While not touching the screw driver crank the engine over and have a friend look for spark jumping from the screw driver to the grounded part. If indeed spark is present verify fuel level. Regardless of what the gauge says, put 5 gallons in the vehicle. Very easy to do (not so cheap to do now days) But fuel gauges read incorrectly all the time. If you have spark and it doesn't run after adding fuel we will have to verify its getting fuel. Fuel pump would be the next thing but lets verify spark to the the engine first. If indeed you do, take a second to pull a plug out and check its condtion.

    Sorry for the delay in response. At any rate we will assume the injectors are fine. Because if the chances of all four clogging all at once are slim. Even if half were clogged the engine would run. Refer to your owners manual on fuse locations for fuses in connection with the fuel pump/ecm and injectors. When you turn the key on the fuel pump should be easy heard. With key on engine off listen carefully it should run for around 3 seconds. Try that a few times and see if you hear the pump. If you do not, continue looking for a power issue. Lastly the fuel pump its self is accesible via removing the rear seat. You can test there for power. The wiring color varies year to half year so to determine which is power, which is ground and which is for the fuel sending unit i'd have to know. However the pump if it doesn't turn on audibley but when you hit the key one of the wires have power for the 3 seconds then that is surely the power in wire. Using a test light to each wire won't hurt anyting.

SOURCE: Nissan Sentra 2005 - Car doesn't start - Continuous relay noise when key is in ON position.

Surely sounds like a low voltage issue. Relays commonly flash between open and closed when the power drops below 10 volts. Also other indicators in your descrp. explain the same. I would suggest giving the battery a good charge. Also if you can get your hands on a multi-meter and verify voltage that would be good. You can get one at walmart for around 10 bucks. Volts DC is what you want. Besides if you get it you'll def find other uses for it. Let me know if you need farther help

Make sure you have the plug wires on the correct plug. Check the ignition timming to make sure it is correct. After running for a few minutes pull the pluggs to see whitch cylinders are running rich. The fuel pressure and volume need to be tested.

My nissan sentra 1.8 has to turn over several times before it starts. what could be causing this?

Have a fuel pressure leak down test performed, the check valve in the fuel pump may have failed and this causes longer cranking times.
