ok i bought a 1990 maxima se 5 speed ran good for 1 damn day.(i bought it monday and yesterday was tuesday), yesterday i was driving to work and it just shut off. no warning just shut off. now i was thinking ut uh timing belt like what heppend in my 89. but it still cranks and everything. so i thought it wasnt getting gas i went and got the fuel pump out of my 89 and put it in whatta ya know(now i had to walk mighy far to get to my 89 so it had time to cool off) I started to i drive it a little ways down 66th street and it stalled again. ok i thought so i checked rotor and cap again rotor did seem warn but i didnt think anything of itbefore. well i changed the rotor because it was 930 at night and stores were closed so i used one of my maxs old ones that still ahd a little life left. then it started and ran fine all the way home so i figured it musthave been losing fire cuz of crappy cap rotor and wires. well i went to get into it and drive it 10 mins later and it wouldnt start same thing just turn but no fire????wtf???????? something must not wanna work right when it gets warm do any of you know what this could be?? ever have this problem? pm me or reply on here if you have any info that can help thanks guys.....

 

possibly

Fuel pump relay, or maybe another one.
Also MAFS

 

maybe the coils bad

 

did u SEE if it was getting fuel?? pull off the fuel line and start.. and see if fuel comes out..(plz dont blow ur-self up)
check all fuses.. maybe u scraped a wire when u were messing around with the pump and its shorting out.. who knows...

 

changed coil all fuel gets to engine perfect it starts like once every 1/2 hour when it cools down. i think it is something with the firing checked plugs and cap and rotor only i can think is distributor?

 

it restarts every 1/2 hour do you think the mass air flow sensor can make it do that? all relays were checked and are working the whle fuel system is fine. how can i check the air flow sensor?thanks

 

ahhh.. how long does it stay on? (temp. sensor)
is it running rich when it starts? can u smell fuel? exaust color

 

Check your Crankshaft position sensor, and also your camshaft position sensor.

 

when it does start it runs fien no richness exaust colors or fuel smells it runs just like normal but then you shut it off ans it ownt fire up again. but today it finally just stopped starting i changed the ditributor and everything and it isnt doin shiznit it kickin my ***

 

how can i check those?? do they have anything to do with firing

 

Mine did this. Its a 93 SE though, no cap and wires. I had a couple bad coils and fuel pump relay. The coils would trip the computer and it shuts off fuel to rails. Somehow that messed up relay....Just my experience.....I changed filters, MAF, Crank sensor, etc with no results....Look for bad wire at head where it can ground. If nothing else try the fuel relay,its in the truck under the latch(on mine), they are cheap.

P.S. my relay checked fine at store and on bench failed under load!
