Rm8k Wira & Jazz GK5 ownership experience-A long way to go

[parakey]

Everything is ok
starter ok
Crank also turning
It juz won't start. Hahahahhaah

If you get a strong crank, then I dont think it's related to grounding at engine side.

Your car is a VDO right? You should check the crank pulley sensor wiring. Is the sensor in good condition? Dirty? Pointing incorrectly?

Crank sensor have chg to a new one.
1st time the engine can start
After 2day dead agn.

This is most likely the culprit

 

[vr2turbo]

Oh....in that case what can I do to make the grounding back to normal?

Old cars, sometimes the old wires resistant very high. Just get some thick grounding cables and ground a few points. My VR have extra cables to engine, firewall, alternator, and car body ......lol

How was it changed? Check the sensor contacts, wires, etc. If crank is strong and it doesn't fire, there's only a very very small number of things that can cause that. You better pray it's not your ECU

Now what I guess is the ecu got problem. Ini kali mati lah.

Not so fast assume ecu lah. Confirm crank sensor Borrow and test again.

what mati...yours only wira ecu.
mine is waja 1.8 ecu...just check online for the cost.When i encounter my weird problem i even bought another unit of 2nd ecu for about RM500.

Apart from bad wiring or grounding, bad connector can cause weird problem too. My friend blm has the check engine light blinking, speedo not working, and sometimes clock will reset. at first he tought its the O2 sensor and speed sensor needed replacement but a Proton tech said his mileages is too low for that to happened and the tech has never do replacement of the speed sensor and die2 said the speedsensor is very durable. One day i swap my meter cluster with him and everything was fine thus we conclude the meter cluster is fsulty. when we reinstall the old meter cluster.....everything works fine, totally no explanation what happen except the connector is potentially dirty(still dont make sense as its well protected behind the meter in the dash).

Now waiting for the checking result. Juz hope is not the ecu problem. Hahahahahaha

My car now always have the speed & high voltage issue. I didn't go and bother it since my meter still can use. Juz when you go more then 100km/h it will pop up.
The crank sensor one I had changed a new sensor already.

Wah,waja ecu so mahal.

It was originally loose. After some time of using, it became looser and then occasionally lost connection.

P0501 & P0113 errors been there since last year. P0335 is your crank sensor. Did you previously change the crank sensor?

Last Tuesday I had the 2nd one after I own thus car.
Hahahahahaha

Some times I think carburetor car is better, for longetivity that is....my old proton saga never gave these kinds of problems, sure the idling wasnt the most consistent, but it will always run.
