i have a 95 maxima 5 speed and i am having problems getting my car started. i am getting spark and timing is perfect. i am geting fuel all the way to my fuel rail but i dont think my injectors arent opening up? any ideas???

thanks in advance for all your help

 

Ahhh ... there's a to this site ....




Really, you post a thread that says 'help' but give us NO information on what you have tried, looked into, messed with, or anything else for that matter. And you expect help .... haha

Need more info I think is the point here!

 

Check for any stored error codes. I suspect CPS being it controls injector timing.

 

Haha like the guys above said you need to provide a story for people to get some back knowledge first.

Just pretend like you were going to a shrink for your car and she asked you to tell her everything you did the day your car broke in detail. And that would be the info that technical folks around here need haha

 

this is what happend.....

when i bought the car it wasnt even running.

the timing was off because i wasnt getting any spark....

i redid the timing and i am getting spark....

i am getting fuel to the fuel rail but the injectors arent openning up...

as far as codes, i didnt have time to check....

any ideas??

 

wow somebody's cranky today hu?

anywho.. do as the man says.. check the codes first...

 

did something crawl up your ***????

 

i already change the fuel rail and the injectors....and also had the injectors out to see if the injectors are openning up but i get no fuel....

 

Okay, again.

There are so many questions you are apparently refusing to answer, and information you're neglecting to share.

You obviously don't want to help us help you.

I'm done here.

 

If you did indeed check to make sure the injectors aren't firing by removing the rail and cranking, then check for power at the injectors, they should have constant 12v on the fat red wire, if not start with the eccs fuses under the hood, in fact you should check all the eccs and ecm related fuses everywhere first anyways. But of course, this is all assuming you read the codes, because if you didn't read the codes first before blindly replacing injectors you are.... welll, ok I'll play nice, but you can't just go about replacing parts.

Also, what on earth do you mean you re-did the timing? You yanked the outer cover off and reset the chains? Or do you actually have a '94 and you fuxored with the distributor?

 

i will get codes this evening.....i pulled out the timing chain and re did the timing....the guy i got the car from had it of 2 teeth....and wasnt sparking... i will also check for voltage

 

So are you absolutly sure that you did the timing correctly??

It is very easy to skip a timing marking or skip a tooth ect ect. You should of mentioned this on your OP

 

I think you need to work on one problem at a time and fix it. First and foremost, pull codes! This is a given, if it's a senor (CKPS, CPKS Ref, CPS) then how are you going to figure it out without either checking codes or replacing the part ?!?!

I think you'll find this site very helpfull, but you need to answer questions in order for us to help you. The people who have been here a while really know their stuff about the A32 (Pmohr for instance!). Once you rub someone the wrong way and upset them, they may not be so willing to help you in the future. See my point?

As for your problem -
You took the TC off and aligned everything and put it all back together, correct? You say you have removed the fuel rail to check the injectors. You need to do as Kevin said and check the power to the injectors. There's a procedure for checking everything and if this happens, then do this ... and so on. The procedures are the only way to go about fixing the problem. They can ALL be found in the FSM - which btw, Pmohr was kind enough to like directly to it for us!

 

i am absolutely sure that i did the timing properly... i had a 3.5 swap maxima before and did timing alot of times....been thru a few vq30's and 2 vq35 swap 4th gen with 3.0 timing...

 

the maxima is a 1995 se ecu but i have a 96 maxima ecu...dont know what model or if it makes a difference....

these are the codes im getting:

long short
03 04 : knock sensor (just changed)
04 02 : fuel tank tempature sensor (didnt change)
08 03 : absolute pressure sensor (???)
08 07 : EVAP Canister purge control valve/soenoid valve circuit (not hooked up)
09 03 : EVAP Canister vent control valve (not hooked up)

 

How long have you had this car. You mentioned that you had to redo the timing correct??

By chance did you hook up the fuel lines backwards????

The fuel coming in goes on the radiator side and the return is on the firewall side IIRC (its been years since ive actually seen a 4th gen fuel rail)

 

I would suggest you get a 95 ECU. I had the same shiz with my 96. someone swapped the engine with a 95 one and none of the emissions crap was there and I constantly had CEL and codes including the fuel temp. sensor.

 

yes....timing is correct...and fuel lines is on proper way

 

ok.....
i am thinking its the ecu....i checked for injector pulse and i get none...
