starting problems!

[biga]

OK i know there have been numerous other threads reguarding starting problems but i juts want all sugestions!
Car take 3 or 4 turns of the key to start! in the morning.
If it is the TPS what do i do? and wat are people fixing methods>>?
cheers guys

I also here a clud noise when i am driving with low revs,Eg taking off 1st and 2nd gear mainly?

[dirtrace49]

;) It probably is not your tbs. It's sound more like you are , or have a bad temp senser. You'll have to check your codes to be sure. I had the same problem with mine.

[biga]

so wat does my temp sensor haev to do with starting my car? i thought it just let me knoe how cold or warm my car is?
cheers?

[DEVILsEXA]

haha u just answered ur own question! It tell tha comp how hot/cold tha car is!!!

anyway!

I just thought i'd reply this thread aswell just incase u dont read tha other one!

B4 we lost all tha posts there were about 7other posts about this problem all said something different but it was the same syphtoms...

Hard to start, Rev lower when 1st trying to take off, and no power below say 3000RPM...

These are all the same problems i have and i am currently working them out!

Tomorra i am changing tha spark plugs and fuel filter and doing tha timing!

So far the Revs lowering problem is partly due to the TPS... U will need a multi metre to set this correctly (PM me for how to!) but i say *PARTLY* because u also have tha problem of low power b4 3000RPM which in turn amplifies the TPS's problem!

U have a choice to make!

1) Adjust the TPS, and u'll a) fix tha revs lowering problem but find u have a surging probelm when u take ya foot off tha accelerator it feels like ya breaking and put it back on u get thrown bak in ya seat! 2) u put up with tha revs lowering problem, but can find a 'sweet spot' where the problem is less and u dont get tha surging!

And do that till i can find out what tha low power problem is then we can fix both those probs at once! then we'll just have to figure out tha starting prob!!!

(in ma mean time my friend get someone to start ur car while u put ya hand behind tha exhaust and feel for a rush of air! if ya dont get that then u may just have a blocked muffler or CAT!

anyway i'll keep yaz posted!

if this was i...
if i turned the key three times and it did not start i would check the muffler for raw fuel as it may be flooding it self, then i would proceed on to get someone to check the timing...ie mechanic with induction light!
if the timing wasnt out then i would start to look elsewhere...like TPS and CAS.
who knows if someone did a timing belt before you and screwed up on the marks. if it is out right at the start then you will be screwing with numerous problems to band-aid this situation.

hey dude

I think that loud clunking noise would be the engine rocking when you accelerate and back off... Check your engine stabilser mounts.. located under your exhaust manifold and intake manifold.

As for your starting problem... Yes i do agree the TPS can be a problem but i feel that the water temp sensor is playing up. Cos of the age of the motors now... The sensor life would be coming to an end... I've changed mine and it did JACK all!!! Still doesn't start on remote start, takes about 6 goes before remote start can get it running. Thats on a 3 second burst.

I'd get the car check over by a decent mechanic and get those moutns looked at!

good luck

I've got a sim prob, in the morn when i start i have to hold the key on till it kicks over i do this 10 - 15 time. when it finaly turns over it real rough i put my foot to the floor revs drops and stalls, i have to keep it above 2000rmps for a while just to get going mean while i've lost 1/2 an hour of my day just satrting the car. And same again after work it wont turn over. A mate said the fuel pump could be F**ked as once it goes it a little rocket.
any ideas.
:hitwall::hitwall:PLEASE HELP IT SHITS ME OFF :hitwall: :hitwall:

16 rmc...
when you turn the key on in the morning...do you hear the fuel pump come on to build up pressure???

16rmc - I think your TPS is out of position.... when this happens it means the throttle is either more open or closed than the car thinks it is. Therefore allowing more or less air in once you touch the accelerator - the result is the engine choking and finally dying. Adjust this and the problem will most likely disappear completely ----> Anyone who has the 'revs drop when engine cold & accelerator touched' should do this... Impossible to have a properly tuned engine otherwise.

Biga, does the clunking noise feel like its beneath your feet? Does it do it occaisonally when you go over uneven road or up gutters? If so, its your swaybar linkages ($20 from whiteline, swap yourself in an hour).

[exa18]

poor biga, you must be so confused by now huh?

[biga]

ok THIS HELP IS GREAT! BUT HOW DO I ADJUST THE tps? IT HAS TWO SREWS > WHAT DO I DO? AND IS IT SAFE??

[DEVILsEXA]

OK Yes it is safe to addjust ur TPS!!!

But i hope u've all read my posts on doing this! as it will couter act! U can slove the revs dropping but u cause another problem where ur driving along and u take ur foot of tha gass and it 'brakes' put it bak on and it surges! *this is NOT very safe for city driving so if i was u i'd leave it and put up with tha revs dropping!
Unless u can get ur hands on a multi meter then u can safely set it up! but once the TPS has started dieing u cannot get it perfect!

* for more info or 'now to' PM me*

As for the starting problem i've cut it down to 1) the fuel line/filter or 2) the cold start sensor thingie (it's like an automatic choke).

anyway i'll keep on posted on my progress!

as for loss of power below 3000RPM CHANGE YOUR PLUGS :D

I am not sure if the proceedure I done was correct, but what I did is put the 2 probes from my multi meter (set to mega ohms) across the 2 pins (top and middle) of the TPS, adjusted it to the point where it broke from the 0 ohms to infinity, then slightly tightned the screws, then got someone to press the peddle slightly about 5mm, and set the TPS to register.

The TPS is like a ON/OFF switch, you can also go to test mode II on the computer and the RED Led should be on when you foot is off the peddle, then when you press it the RED Led should go off.

I am not sure if the 5mm setting is a good setting, but for me it seems to have worked.

While your at it, inspect the pins on the TPS and in the plug, if they arn't clean, then try some hot water followed up by some Carb Cleaner, it should remove all the crap out of it. Also check for a nice tight connection, if there isn't then adjust the pins a little.

Hot Water removes the blue coloured corrosion, and the carb cleaner removes carbon and a fair bit of other shit.

I'm not that mechanical minded, so if i take the car to a workshop they will know waht im talking about with the TPS?

[DEVILsEXA]

Yeh thats about it!!!

Well i think i've found tha answer to ALL my problems...

there are 6 yes SIX vaccumm lines with no homes!
So Biga go check all ur vac lines! if there are any unplugged or look like they need replacing then thats where are problems lay! If u dont have any out of place then i know that it's not ma problem! And i wont bother with them for now! I dont have anoter Exa to look at so i dont know where all the lines are suposed to go!

Anyway thats my update for today!

Craig.

(Yes that is how u adjust tha TPS top pin is Red Middle is Black and bottom is nothing!)

Skozzy: When doin that mode two test... does the car need to be running? coz mine doesn't do that aye!

[DEVILsEXA]

WOO fukin HOO

:trippa: :cheers: :hippy: :D :heehee:

Guess what... Figured out where they all went... getting better with each one i put in! Got to tha last one... put it in and there ya have it she started running sooo smooth once again!

Now as for the starting problem i'll have to wait till morning to get tha results (or do tha testing shoudl i say *cold engine*)

If u have a workshop manual look at page 135 find the 'air regulator valve' now go to ur cars... have a look at tha white connector (mine is actually broken), but take it off and check tha pins are clean as mine were very coroded (prolly due to tha broken plug), but i cleaned em up and shoved tha connector bak on as well as i could and taped it there!
You could all try this also... start your car with that plug disconnected and you'll find that the revs keep dropping untill tha car stalls! This is kinda of what happens when we start... (if we're talking about tha same problem) Car starts but stutters and slowly dies... "air regulator" atleast this is what i'm thinking for now!

Craig.

P.S. sorry for tha long post! And more to come as i'll keep u informed on my progress!

[djmike]

just got my exa and yep i gots this problem where the car takes 3 or 4 times to turn over.. if u hit the accelerator the car will stall..

so yes.. i see its a common problem :afro:

[DEVILsEXA]

Ryte so for this problem it's...

1) Check all vac lines are in place

2) Check and reposition ur TPS using a multi metre

3) Check and reset your timing (using tha CAS and timiing gun)

4) Take off all plugs to the sensors and check to see if they are clean... refit and make sure it is a nice firm connection.

5) Now check reset and check again tha ECU (under passenger side seat) then if u get 55 all should be good if u get any other number just post it here and we can figure it out.

Sound like an EGR problem or clogged CAT but best to start by doning the basics

1. Clean all Connectors , Tps Chts, Tps,02 , Air Control, AFM
2. Check Timming
3. Check Vacuum System, 20+-Lbs
3. Check Spark or Replace Cap and Rotor.. Low Spark
4. Check EGR Valve .. Push Up from Underneath see if engine changes speed.. check tube is not leaking or broken
5. Loosen Exchaust at Manifold Connection.. a Bitch
6. Leaking Injector.. pull plugs and check for wet.. change plugs use NGk
7 run ECU test

(from mechanic! whats EGR???)
