Engine light does not come on

Hello friends, my 307 vehicle is 2004 model, I have a question for a few days, when I open the ignition, the engine does not come or it comes late, it works after it arrives, we have connected it to the computer, no problem.

a strange situation, the vehicle cannot communicate with the engine ecu then does the engine start when the engine light is not on. The first thing that comes to my mind is oxidation in the sockets or contactlessness in the cables.

the starter is running but does not work late or after running, the tachometer decreases to 0, the battery light is on, then it gets better

I think my teacher has weakened like a hard battery and have the battery history checked suddenly. voltage status

the battery is 5 6 months old but I have it checked so does it cause such a problem after the battery is stolen

Generally, this type of problems can be done when voltage imbalance or battery is not fully charged. this can cause such problems.

I have to check it starting from the battery then I am having a problem with the ecu, which was messing with my head.

Exactly, if the battery is already new, it may be a situation related to charging. I hope it is not from ECU. may cause trouble from the repaired place again. going from cheap to expensive.

battery voltage and charge normal

We did not see oxide or broken in ecu connections.

I understand that my brother may need to find and test a quit ecu that you can return.

I will try tonight to borrow the medicine from a friend, but how do I make the issue of harmonizing with bsi?

If the engines and ecu models are the same, brother, it can't be a problem.

I do not know the original brand of the ECU that I tried to remove from the vehicle, but before I changed it with bsi and started my vehicle.

probably working teacher

ecu came out the problem is i got the bsi indicator and the ecu to my complete set 2003 brains break down our glow roles and switch to 3000 cycle shortening
