It sounds like the engine coolant sensor is bad ?

1998 nissian maxima- new problem won't start in cold or sitting it starts after almost killing the battery and having to jump start. runs great when running shutvoff car and starts back up then after sitting awhile won't start again help please. changed plugs cam sensor computer still same problem

Next time it refuses to start-do below

Get a starting fluid or ether and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

the crank and cam sensors were changed it wont start with starting fluid sprayed into throtle body rulinmg out a fuel problem very hard starting or not at all it seems to kick back like its out of time but it runs fine when it gets running

Test the coil's primary and secondary windings resistances and the crank angle sensor

my 1998 nissan maxima is hard to start and engine light is on.just had a used engine put in.code comes up 1335.what does that mean?

Code is for Crankshaft Position Sensor located near crankshaft by oil pan.

I have a 1997 Nissan Maximum with 108000 miles. In the past couple of months, I have had intermittent trouble starting the car. Sometimes it starts perfectly at the first crank, sometimes it starts but with a little missing first then cranking gets sluggish and slow, to the point where the starter makes the "ratcheting" sound as if battery was dead. Then after waiting 5 minutes, tried again and it started just fine... very strange. Had battery and alternator checked... all is good. Dealer can't reproduce problem so they can't explain what is wrong. They suggested it might be short in ignition wiring but can't gaurantee they will ever diagnose. They also suggested towing in at the 1st sign of difficulty, but that could be expensive and huge inconvenience if I'm long distance away (!?!)
I can't see any pattern - hot engine, cold engine makes no difference. Once started it runs well.

Hi chris midon,

Thank you for the donation.

The symptoms described seems to indicate a bad battery. If you are using maintenence free battery, there is a possibility it has internal faults. It can work perfectly one minute and the next it fails. I have encountered a few of these.

The other possibility is a bad starter. The brushes might be failing and intermittently when the carbon contacts are not good, it will fail to crank or cranks weakly.

I have a 1997 Nissan Maximum with 125000 miles. In the past couple of months, I have had intermittent trouble starting the car. Sometimes it starts perfectly at the first crank, sometimes it starts but with a little missing first, and once in a while I can't get it going unless I give it some gas first. I can't see any pattern - hot engine, cold engine makes no difference. Once started it runs perfectly. I ran fuel injector cleaner and octane booster through, seemed to help some but it is still a problem.

take off the fuel pressure regulator vaccum line, is there gas in it? if so it needs replacement.

does vehicle crank normally when it wont start or is it slow and sluggish, faster?

have a fuel pressure drop test. and regular fuel pressure test.

Car has a hard time starting it will start I have fuel and spark its just a hard start need help its embarrassing

what is the fuel pressure when you try to start it. it may have to build pressure.
is the check engine light on??
have had basic maintenance like plugs, etc??

Roy

I haven't check the fuel pressure the check engine light is on and I have a code 141 o2 senser

Yes I did a tune up I even change the crank position sensor and the cam position sensor

All compressions ok?

Car has a hard time starting it will start I have fuel and spark its just a hard start need help its embarrassing I haven't check the fuel pressure but I have check engine light on the code is p0141

Check the coolant temperature and oxygen sensor and also do fuel pressure check-

Quit reposting no worry be so advised there's other people waiting to get fix ahead of you- Don't comeback to this post-stay on the other one

I tryed that I even ground the engine in 3 different places

what to do to fix proublem

Hi jeffreyj, Welcome to 2carpros and TY for the donation.

Do you have a check engine light before this problem started and also when was the last tune-up?

Do a fuel pressure check and get back with the readings I need this info.

replaced clutch had fly wheel resurfaced customer came back five months later complaining of hard start cold but says after driving warm car starts fine after took nissian said fly wheel could be put on wrong they tell me there 6 different ways for flywheel can go on. does any body now of this.

Hard start? Do you mean like parts binding, or cranks ok but won't start? If the latter check the ECT and air temp sensors, would be good if you can keep overnite, and test these two after at least 8 hours down time. They should be within 5-10 degrees of each other...I don't know about the flywheel problem. It would seem to me if it starts ok warm its sensor related, if the fly wheel was the issue, it would get worse with heat yes?

I own 1996 maxima
it have 146937 miles
In the morning it is very hard to start
and if i park 7 or more hours it hart to start.
I replace d a cooling temp. sensor and air flow map
but it do the same
Thank
Frank

Check the fuel pressure if its within specs if okay-Clean out the IACV-AAC and the FICD valve and test the throttle position sensor.

the car is hard to start when cold (morning)
once it starts it runs 100% a OK

I get ecm code 7-7 and 10-5

for the 7-7 code
I am not sure if I should replace the fuel presure regulator
or the rear oxygen sensor I am thinking the preasure regulator, as I dont belive the oxy sensor would effect the starting
I have removed the ground cable from the battery
to the engine and body and really cleaned them
up real good filed them down on both sides also filed body and engine connecting points, they realy were in bad shape

I also dont think the 10-5 error code would cause the hard starting and was going to troubleshoot that later
Am I on the right track

thanks duffy55

10-5 EGR solenoid valve will cause hard starting. Clean your EGR valve and make sure the solenoid is not sticking. EVAP canister purge solenoid also uses the same code, so you may want to check this solenoid as well.

The starter seems to turning, there is a high pitched whiring sound, but the engine only occasionally turns over and starts. I need to confirm if this sounds like the starter, and if there are any other things this could be.

That sounds like the problem... the starter is connected to the fly wheel by where the transmission and motor connect... have the batter disconnected and take the starter out of the car first then bring it in because they will probably have a core charge for that...

Sir is Nissan maxima qx 1995, Is doing hard starting, no sparking on the plug sir. Thanks and God bless.

god bless you to brother,i would get a universal spark tester from like autozone or advanced auto .it goes between the spark plug and the spark plug wire and measures how much spark the ignition has.don't get the kind with the light,get the one that measures spark.test a few cylinders and let me know.

My car, when starting first thing in day, or when it sits for a over 3 hours; shakes. After driving for 2-3 minutes the wobbling goes away for the rest of the day, unless car sits for more than 3 hours. Just stopping, turn off for an hour and start again, there's no shaking/wobbling at first. The shaking is when I back up the car out of driveway.

My problem is that, when I took it to local repair shop, they diagnosed my car as having rack & pinion problems and got charged close to $900. I never had problems with steering at all. They also included alignment, although I didn't have problem with that either.

All I know is I'm out $900; but hard start is gone. What could problem have been and could it have been cheaper to fix? I think I got ripped off for a cheaper problem (oh, 5 out of 6 fuel injectors were already replaced, but car didn't shake all the time to need last injector replaced, plus fuel injector replacement would of been cheaper). Help, please!

Are engine mounts more expensive than rack & pinion repairs for this car; as in researching this it seems I might have had engine mount problems. Also 2 belts were replaced, would it just have been the belts (which repair shop said were so old that they broke while doing other work on car).

hi Lboeche,

If the misfiring is only during cold start, you need to check the plugs and coils for misfiring.

Another thing to check is the fuel pressure.

The steering rack has nothing to do with starting problem. While doing the steering , the alignment would be affected if they had replaced the rack ends or tie-rod ends.

The mounts should be cheaper to replace.

The car is a 1995 Nissan Maxima. the engine was just put in and the fuel will not go past the fuel regulator but we have tired three of them. They can't all be bad. If you switch the lines and put the return on the regulator you can get it started with some effort and it will run great but as soon as you turn it off it is hard to start again it floods out. If you put the lines back the right way it won't start at all because the gas does not go through. We have replaced the crank sensor, there is fuel injector pulse, the fuel pump is pumping 60lbs. to the regulator. We have run out of ideas.

Fuel pressure specs.

@Idle-with vacuum should be 34psi w/o vacuum-43psi

Better check the return line for clogging if its not clogged you need to triple check what's happening with pressure regulator.

BTW do you have vacuum at the regulator?

hello again. i have one more problem of the vehicle. I changed the trans to a used one and now its working fine. But now its having a hard time starting. Before i changed the automatic trans it was fine. When i start it it takes several times before it starts. could it be some sensors on the trans or something else.

You may have damaged a vacuum hose or something like that during removal and installation. I am going to give you a walk through diagnostic on hard starting engines. When it talks about getting trouble codes pulled, go to any Advance Auto ro Auto Zone and they will do it for free.
