2003 nissan extra has gas has spark wont start

could be a problem with engine electrical or still with fuel delivery. unhook a fuel injector line while it cranks and see if it shoots out spurts gas, just as the fuel pump line is supposed to shoot out a stream of gas while cranking. if you replaced the fuel pump, and no gas shoots out the disconnected fuel pump line, there is an electrical problem, (fuse, relay or wiring issue) to your new fuel pump. if the gas spurts out the loose injector line, then move on to electrical:

first ensure your ignition coil has spark by disconnecting the coil ouput lead and shorting it out to the chassis of the car. you should see a spark, when you short that circuit while cranking. if you have spark, you will have to move on to the spark plugs/ cables, then the distributor cap/coil packs.

if its part of the electrical system, it will be sensitive to temperature/humidity, and that may be why it only fails to start early in the morning. if it were the fuel injector, it would be more likely to start cold, and NOT re-start after it had already been warmed up and cut off recently.

TIMING IS OFF,BELT COULD OF JUMPED,

dear friend ,you can check the engine, starter ,and the engine itself fault .

Hello you will need to replace the spark plugs you quoted it is getting lots of gas so your spark plugs are wet.disconnect your battery while your replacing your spark plugs once finished replacing the spark plugs reconnect the battery now try to start it should start up.

Sounds like the ignition system is not firing the spark plugs if starting fluid and gasoline doesn't solve the problem.

Verify by putting a spark tester on one of the spark plug boots and attaching the spark tester to the engine block or ground.

I have the same problem with my 2003 nissan sentra gxe. I don't know about under the hood, but I was told that the gas filter needed to be changed. Something's wrong with the gas intake to the engine. I had it "fixed" but it still does it a little bit everytime.

You pinched the fuel line????
If you crank for too long to start the car, the engine will "flood", this is why the plug was wet. It had too much gas and wouldn't start.
Pull out ALL plugs and dry them off.
Install them.
HOLD your gas pedal to the floor and crank.
This will stop gas from entering the engine.
you need to get that extra gas out beofre it will start.
If you have so much gas in there you can do damage to your engine!!
Now after a few crnaking attempts with your foot to the floor, take your foot of the gas pedal and try to start it again.
But remember if it doesn't start in 3 tries, you need to do the pedal to the floor once or twice to remove the excess gas.
When you crank the car to start it sprays gas into the engine, even if it won't start. So it very easy to "flood" the engine, and then you'll have a hard time to get it going!

Take one of the spark plugs out and let us know what it looks like. Dry and light grayish tan means you have spark but fuel supply problems. Wet spark plug that smells like gas means it is more of a spark issue.

Good Luck

need to know how fuel pressure if way below 36psi maybe why it wont start

Sediment from the bottom of the tank could be blocking your fuel filter. Replace your fuel filter.
