so i bought an A33 SE over this past weekend and have some ????


the previous owner had removed the CEL bulb ( checked under the vehicle & the most obvious answer is there is a test pipe and no cat ) but i have yet to scan for DTC's.

at a cold start this morning i noticed it took a few tries to start the engine , and when i mean a few start i mean crank,crank,crank,crank,crank,crank.....let go of key, turn key to run and crank,crank,crank,crank,crank,....let out key then try again , crank crank, push in accel pedal while holding jey to run, crank crank crank crank..vroomm....engine idles fine , let it warm up then engine starts fine after warmup and shutting off then restart.

No problems starting after engine is warm. I am not familiar with the VQ motor as i have been an SR20 guy all my life, but it does sounds like a cam/crank position sensor to me. Maybe even a fuel pump or NVIS issue .

anyone ever hear of this? I mean this Maxima i bought ( for $3900 US ) has no rust and an awsome body & paint ( pearl white ) but that issue i am having a problem with.

when i get to take time to check fuel pressure & scan for DTC's i will have an idea what is going on. Previous owner was a " ricer " kid who had hacked some things up on this and i just want to restore a nice looking 2000 SE.

when i scan for DTC's i will post here what the ECU says.

thank you Orgers for any help

 

may be - should leave DTC though.

not likely IMO.

 

Check for code and let us know. does it do this every time? or just this once?

 

tried again after a long cold soak las night and it had a long crank altho not as long as the very 1st time. When i get to work i will be bringing my DTC code reader, since the previous owner thought it would be cute to remove the SES light bulb.


Also, do the A33 SE's have a chipped key? Because the key he gave me isn't an OEM key , it looks like the generic keys you might get at ACE hardware. The clock does have a red security light next to the clock, and it didnt light up last night when it had an extended crank time.




...the saga continues

 

yeah i'm going to check for DTC's assuming the previous owner didn't decide to slice the DLC wires




haven't checked to see if the fuel pump makes the bbbbuuuuzzzz noise when i turn the key on before starting, will check this morning and report

 

ok so i grabbed my code reader & to my surprise, it had only 1 dtc?
P1336 - Crankshaft Position Sensor (POS) (COG)
edit: looks like the 2000 has 2 sensors 1 position & 1 reference .... how do i determine which one is faulty?

looks like i may need a new crank pos sensor ? i'll check the connector & wiring, luckily it is located right next to the oil filter .

one more question, this thing has no catalytic converter, shouldn't i be geting a dtc for that also? previous owner had a test pipe installed & no cat..

 

just went and tried to start it again and now it doesn't start for ****....so which sensor gets replaced? the one by the oil filter or the one by the tranny?


i know the circuit is ok since i was able to drive it 120 miles

 

there are three sensors if i remember correctly. two cam position sensors and the other one i thing is crank position sensor?

You can rule out NIVS by watching your security light. If it stays on while you are trying to crank the NVIS isnt receiving the signal from the key

my money is on one of the 3 sensors above.

 

iirc there are 2 crank sensors

i pulled dtc p1336 crank pos sensor, but as i read in alldata there is one called "position " and one called " reference"


i did see one by the oil filter and i read one is by the tranny bellhousing.

i know the circuit is good beause it has an intermittent no start. meaning it won't start w/e it decides not to start. can't be a wiring problem and can't be an ecu problem, so that sensor has to be bad ...

found one listing on advance auto parts site

ok so which one usually goes bad ?
i have a 50% shot at getting the right one

 

Straight from FSM:

hey man thanks i appreciate it, it looks then to be 23731TA located on the bell housing side.


will look into the situation further , hopefully it's nothing mechanically like missing teeth on the flywheel
