mitchell1 you are not telling us what you have checked regarding the fuel situation. Now here is how it all works according to the SM:"
The ECM activates the fuel pump for several seconds after the ignition switch is turned on to improve engine startability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump." So what the means is that you need to check your pump, the relay after that the POS and the camshaft position sensor as well as all the wiring in between. Then if still no error found you need to check the ECM.
Without sending you on a wild goose chase I recommend that you check the fuel pump fuse (see image for loaction)
Next is the fuel pump relay
TEST ITEM
FUEL PUMP RELAY
CONDITION
Ignition switch: ON (Engine stopped)
Turn the fuel pump relay “ON” and “OFF” using CONSULT-II and listen to operating sound
JUDGEMENT
Fuel pump relay makes the operating sound.
CHECK ITEM (REMEDY
Harness and connectors
Fuel pump relay
The relay is built into IPDM E/R

Checked fuse it's good changed relay nothing changed pump nothing was getting code 0702 and 1574 but car was still running. When I shut it off and then back in again the 1574 problem would go away do u think those codes have anything to do with no fuel cause it starts if I spray starting fluid
@edwad same car? Same problem? Same engine? Give us a bit more information.
Oldturkey,
I have the same problem with a 2006 Nissan Altima 2.5 S except that it is intermittent. Sometimes it starts sometimes it doesn't. I am leaning toward replacing the Crank & CAM sensors after reading what you wrote.
I'd say crank angle sensor.
I have a similar issue on a 2004 nissan sentra 1.8L car will crank but wont start, throw a little starting fluid at it and it starts sometimes but not always. Pulled fuel line of at fire wall and fuel pours out but seems weak. I've tried 2 fuel pumps, fuel pump relay, plugs, coils, crank and camshaft sensors all out of another running sentra and even an ecm, and still nothing?

OK easiest answer is if you don't hear the fuel pump prime. Then suspect bad fuse or pump. Check fuse box either in car or under bonnet (hood). If fuse is good, chance are your pump is bad.
It can only be one of 3 things, fuel, air or spark!
Air isn't the issue, spark probably isn't the issue. If it is a fuel injected car, turn key on as you would to prime it, then turn off. crack the nut on the fuel hose to the fuel rail, start undoing it, if no fuel comes out. Bad pump, if fuel dribbles out but not under pressure as it should be, bad pump. Change out pump. If fuel comes out under pressure, tighten nut. Turn ignition on, as you would to prime pump, then off again.
Wait ten to 15 minutes. Then crack that nut again, should still be pressurised, if not bad pump.
If pressurised, then your pump is prob on the way out or just silent. Check fuel filter, could be clogged, change it out and try to start, if starts. I'd order a new pump anyway. If doesn't start, bad pump.

Ware is full filter located 2000qwest mini van gxe
Put new fuel pump in still no spark
I figured my 04altama is the crank and Cam sensor so I taught I was pulling one of the two but I think I pulled out the oil sending unit instead ??

There are so many people helping with their experiences and throwing parts at their cars, lets start with a real world back yard mechanic diagnosis without a scan tool and no experience. Can you run power, 12 volts to the connector back at the fuel pump (correct wire of course) and see if it will work and start the car. We will work our way back to the fuel pump relay as the computer controls the input to the relay as the computer also needs to see certain items working prior to letting the car start, you say if you spray in some form of fuel, the engine will start, this does point to a fuel related problem. Do you have a volt meter to check for power and grounds at the fuel pump connector while trying to start the car?

Hey my altima when i purchased it was doin same thing . the fuel injector fuse under the dash was blown .started right up after replacing fuse ..the car was at a shop for over a year they could not start it..they said fuel pump bad lol i started 2nd day after i got it home
Omg! I had no idea there's a fuse for the injectors, just put in new fuel pump, relay for pump is fine, as is 15 amp fuse for relay. So, am going to check injector fuse. I'm praying this will work. Say a prayer for me.
Did this work

Im not sure if it is the same on the 2002 but on a 1999 there is also a ignition relay that is behind the sterio mounted to floorboard if you lay in pass side and look behind radio you can see it but is pretty hard to get to . Ground a test light and with key in on position probe the 4 pin connectors and one should make the fuel pump run if so change this relay and you should be fine . Ps… this relay controlls fire to the distributor as well as fuel pump so if it has no spark or fuel it would be my first guess.hope this helps

Wow, I've looked at online Manual's, diagrams,etc and didn't find anything about a relay behind the stereo. That could be the problem on my 04.
Ben rodeheaver, I have a 03 altima, just wondering if your 04 had a relay there or not .might be what's causing me trouble if it has one there

Alright , Ive seen this over and over and over and everyone always throws parts at the problem without knocking wtf is going on really, turn the key to the on position , is the theft light flashing? BINGO!!! IT WILL NOT GET FUEL IN THEFT MODE , WHICH IS WHY YOH GET THE CRANK BUT NO START!!! unfortunately your car either forgot the key , or the key itself took some damage either way just have it relearn the key , put it in the on position , and leave it for 15 mins or so or get a new key and have it programmed , YW

You're the man. That solved it!
What code would that pull up. I'm just curiouse, and how do you get your car to learn the key again?
Thanks D, I knew it was somewhere in that area because I seen the anti-thief light flashing… you are the man..????
Can you bypass the theaf mode

So, my 06 Altima stalled while I was going 50mph & wouldn't restart. Battery, fuel system, alternator & starter all worked fine & no issues with fuses or wiring. Cam & crank sensors in good condition as well… I was ready to just scrap the dang car but decided to do a Google search & voila!! It was the friggin ignition relay switch….less than $10 fix!!

How did you find the ignition relay?? As stupid as it sounds I have called parts store even the Nissan dealership and I cannot find one. Everyone says they don't have it. My car's doing the same thing I've replaced everything. And an at my Witt's end..
Its in the fuse box under the hood on passenger side front

with the belt off, verify that the components it turns will actually turn. If one is starting to size this could cause the engine to crank at slower speeds which may not let it start. Ac, water pump, tensioner… check them all..

First, check the battery power for its full potential power. Test, battery. If results from test say battery is:Good, then crank the engine and hold down the gas pedal. If car still does not start, visually inspect the fuses. Focus on the fuel pump areas.

I'm having issues with my maxima not starting. It cranks and starts after getting a bit and I think holding down or pumping gas pedal helps it start. I noticed you mentioned to hold down gas pedal so I was wondering if you might know where the problem may be coming from if pressing down the pedal helps to start engine?
when i hold down the gas pedal and start the car it takes more pressor and tries to start and after some time it starts then there is no problem came in the car in whole day.

I believe it's the fuel pressure regulator, not the pump or relay or fuse…

I'm not intimately familiar with this vehicle. Did it say which sensor? Take it to an auto parts store. They'll read the codes for free and help you get the right part. Anyone in the USA who works on their own vehicle... I highly recommend a Chilton or Haynes manual. It'll help you locate parts and replace them.
I have a 2002 Altima it will crank but wouldn’t start my husband took of the serpentine belt and it started and ran put the belt back on and back to crank but won’t start I’m puzzled by this. What is going on here?

I also have this problem with my 2006 Nissan Altima. Did you find a solution?

Hi Guys
i have a 2004 Nissan Almera
the vehicle was involved in accident (Front Smash) and Air Bags deployed.
I drove the car home from the accident scene. After returning from the Panel Beater the car refuses to start. It Cranks but wont start as the injectors wont open.
i checked everything, Relays, Wires, Changed the Fuel Pump, Computer Box, Did Key Coding, Changed Spark Plugs, Checked the Harness etc. EVERYTHING.
I Dont know what else to, any advise?

my 2005 Nissan crank wont start changed fuel pump, crank , cam and mass air flow sensor, spark plugs , and coil packs . But still cranks act like it wants to but wont start . Any body hve any suggestions besides trashing it

Scan it for codes

Yep, I also have a similar issue. 06 2.5s Altima. Had missfire issues from blown head gasket. I replaced that myself as the dealer wanted $2000(14 hours) for the job that took me.... maybe 8 hours of total worktime to complete. Prior to replacing the head gasket we replaced the injectors, coil packs, spark plugs, o2 sensors, cam sensor. After replacing the gasket I tested compression and had no issues there. Didnt want to start at all. However it started after unpluging the cam sensor and ran perfect unless you gunned it (I thought maybe the vvt solenoid wasnt getting oil pressure). Sure enough, we were missing the O ring that goes there. Now we have no spark. And its also not starting with cam sensor unplugged. Ive checked the timing and had my father double check all work (20+ year mechanic) He confirmed that I was on the money. Coil packs have power and ground but not seeing anything from ecu triggering the coils. Ecu does connect and communicate perfect. If I anyone has any ideas let me know.
