Help...Help...Ayaw mag-start: Automatic Transmission Car

[chrismartin]

Lately, bigla nagloloko starting ng automatic
transmission car namin. After turning off engine
or parking it less than about 30 minutes, then
pag-start mo...ayaw start........Then pag-ginalaw namin
shifting gear up and down.....then start mo ulit...mag-start
na engine.....Last few days, we have to do it about 5 times
before it starts.....Pag park naman namin ng matagal...one click
lang start na..........By the way our car is Nissan March 2002
Model..Its battery is still new......Hope you can help us guys...

Thank you and Happy New Year to all!!!!!

Top of mind ko, starter solenoid. Pwede rin carbon brush ng starter or starter mismo.

Happened to me once also, turned out starter solenoid lang pala.

Hello,

It has nothing to do with the transmission, my Alty was like that before too, the prob is your starter... AT requires a bit more juice for it to start properly, unlike in MT. Battery and starter has to be in tip top shape.

Yup, happened to our office's Suzuki APV AT. Starter solenoid dumikit. Baka pwede pa namang madala sa linis.

If you move the shift lever and it starts after you do that, it's the neutral safety switch - responsible for turning on the reverse lights, allowing the ignition to only start in neutral (N) or park (P) only.

as you said ng ginalaw mo yung shifting stick up and down, probably yung safety switch nga ang sira. automatic transmission will start only on park position, others pwede rin sa neutral.

[Galactus]

I'm sure the TS knows that he can start the car only P or N. After all, he's had the car for 5 years na.

Thank you for all your prompt replies.....

We only start at "P" and "N" lever position. The problem I described above
is a "No Crank" starting problem. It seems that there is no electricity supplied
to the starter.....upon moving the gear lever up and down there is this sudden
click sound that we hear.....after that....we can now start the engine.....But lately
as I mentioned above, we are having a hard time starting the engine.......Something
strange thou is when we parked for approximately 30minutesor longer....the cars starts fine.....Before we have it repaired I hope you can share some inputs as my reference to compare notes with the car shop mechanic....Thank you very much

baka yung safety switch talaga ang sira or the relay. maybe that explains why pag matagal naka-park, yung switch or relay got a good contact pag matagal naka-engaged. of course input lang po.

Better be sure and check mo na muna ang safety switch. I guess mas mura i-replace ito rather than yun starter solenoid. Kung naayos, eh di ok. Kung hinde, starter na ang tignan ninyo.

There's no realistic way for us to diagnose your problem because we cannot look at the car and see for ourselves what is really wrong. Best estimates can be said but as always, with online forum advice, take everything with a grain of salt and consider all possible options.

Two of us have already mentioned the neutral safety switch. Why did I say that it's the switch? Because it's happened to me before. Starting is intermittent, there's no pattern as to whether it would start or not. Sometimes it would, sometimes not.

However, since the neutral safety switch is linked to your shift lever, if your transmission or engine mounts are shot, this may also cause your shift lever not to engage Park or Neutral. Or right when you park, do you shift to Park and let go of the brake to make the transmission "catch" and you hear a click? This confirms that the transmission's parking pawl has engaged properly. Sometimes you can be in a hurry and just shift to Park, pull on the hand brake, switch off the AC, radio, etc and take the keys out without allowing the transmission to catch. This is more noticed on inclined parking, when parking on a hill or steep ramp.

Yes, there won't be any sound if the safety switch has not engaged and you attempt to start the car with the key. This is because the safety switch prevents the car from starting in gears other than P or N, and if it does not engage in either, then it won't even click at all.

check if your shifter has a slack as well, sometimes the AT cable (forgot what it is called) gets stretched a little and it'll cause your gear lever not to make proper contact with the supposed gear.

My Nissan before had this problem, wasn't really the cable, but the rubber bushing that holds the end of the cable was worn out, causing the shifter to have 1/4" movement or so, if you move it to a gear, it doesn't make contact with whatever it should contact unless you nudge it a little more.

Good day!

May contact details ka pa ba or address nung pinag-pagawaan mo?

Thank you very much.

hindi kaya may switch na naka connect sa transmision mo papunta sa starter kaya nag kakaganun?

kasi kung sa solenoid or starter lang ang sira dapat di na iistart yan

at saka sabi mo ginalaw mo yung shifting gear biglang umistart?????

check the transmission switch as others have already mentioned ... it probably have developed poor contacts and is affected by temperature, which could explain the 30 minute cool down

maki ride sa topic,
what if ithis happens on a manual car, starter solenoid na ba?
as in brownout talaga. wala man lang redondo
occasionally nangyayari sa kin. 1 year ng ganun
nag start naman after a few tries

medyo kulang sa detail kung ano talaga ang problema pero try natin isa- isahin:
1. check the ameter kung gagalaw if you turn on the key. pag di gumalaw ang ameter may problem sa electrical, fuse or loose contact.
2. if your try to start and you hear clicking sound pero ayaw umikot ng starter, pwedeng may problem sa susian or may sirang relay. if no clicking sound at all baka fuse lang or loose connection.
3. kung umiikot at starter pero walang redondo pwedeng walang kuryente. try pull out yung nakakabit sa spark plug ilapit mo sa makina yung tip then start see kung may spark (ingat lang medyo masakit kaya better to hold it with a plier). kung wala baka loose connection lang.
