hey guys i dont really know much about mechanical problems and what not so bear with me. my car wouldnt start, it wouldnt even turn over so i decided it was the starter..... replaced with new starter and my car turned on.....great then after parking and going into a store i came back and it wouldnt start, it would sound like it was about to but it just wouldnt turn over, and the thing is sometimes it will turn on but other times im stuck like chuck............any solutions on what might be going on??? ive been told maybe its the fuel filter or pump then i was told its my ignition coils.........please help out a fellow org'er

 

how's your battery? have you tried to jump start it? got that route.

 

Unplug your MAF sensor and see what it does, if nothing changes...it might be that.

 

i thought it was the battery too..... so i went and got my battery tested and it was dead..... so i got a new battery and nothing changed...ill try the maf today went i get home and ill let ya guys know...... what are other symptoms that it could be the maf??

 

ok update on my car...........still nothing.....my car just doesnt like me............ i tried unplugging the MAF sensor and nothing changed so im thinkin its the maf but now it sounds like something is grinding when i turn the key, i cant even jump start it....... how can i test to see if its the alternator??...........i was also told that my timing could be off?? how would that happen tho???

 

Slow down ... I read the entire thread, but it's hard to keep track of what the symptoms are at present.

Does the car turn over but not catch? or is the problem that the car just won't turn over?

 

If battery was dead when tested and car started after u got a new battery and a new starter, your altenator is no good. Maybe im wrong but I would look into it.

 

the car does turn over but wont start..........i dunno man........ i checked the spark plugs to see if it was gettin spark and it wasnt so i changed the plugs since i was going to anyway down the road and still nothing has changed except for the fact that now with the new plugs it looks like its not gettin spark...........i talked to a mechanic over the phone because i cant even jump start it and he sounded really confused as to whats happening, an all he said was i have to get in there and look but it was a nissan mechanic an the diagnostics is $90 just for them to look at it!!!!!!! an the car was being towed alot before this happened i dunno if that is a factor in it not working or what

 

Try your other key. Might be a keyfob problem.

 

i thought of the keyfob thing as well and nothing

 

no spark... so check the coils...

if you're getting spark and it's turning without starting.. look at your fuel system.. maybe bad fuel pump, clogged fuel line or filter, or even bad gas

 

Cam/crank sensor issue is my bet. Probably dislodged a sensor when you changed the starter. If you are not receiving spark, the plugs should be nice and wet with gas after 30-45 secs. of cranking the engine.

BTW, clean your battery terminals and inspect the wiring harness to and from the battery and starter for corrosion. You probably wasted money.

 

fuel line isnt clogged because i unplugged the line and turn the key and gas spilled everywhere...lol but maybe it was just a bad job when the starter was installed and pushed the cam/crank sensor, im going to check that now. by the way where is it exactly??

 

Sounds like a bad engine ground possibly. Is that main ground that goes from the battery to the body to the engine on ? It should connect right around the area where the upper radiator hose attaches to the engine.

Personally I would look at sensor readings while cranking the car over to see what it does read. I'm seeing a possibility of that wire being knocked off. Do you have a aftermarket intake on the car ? Is your boost sensor hooked up ? Its the one that sits on the air scoop that runs from the radiator support to the air box. Only 1995-2000 Maximas have this sensor, 01s have utilized a MAP/BARO sensor into the ECU just like the 02-up cars. Boost sensor will cause the car not to fire up eighter.

 

yua i checked the wire that connects to the battery ground to the tranny and its on there tight and i do have a injen CAI the sensor that hooks into the CAI is hooked up too
