After change batteries car won’t start

[Tero]

Hi
I have problem with start engine. Everything looks good with electric stuff and starter is working but car won’t start. I have a few keys , two masters and one subkey. When I used subkey immo indicator light is not showing. That same is happening for first master key but when I used second master key emergency lights begins light and after one minute or something like that car has short weird sound but it’s not alarm and after another one minute sound repeats and so on. I don’t know what it’s it and why my car won’t start. Everything works good till changed batteries.
car has also factory alarm but I know where shut it off

Whats the voltage at the battery? Immobiliser can kick in if the voltage is low.

If you have two batteries in parallel, you might want to disconnect the negative from one and measure the voltage on each battery to make sure one bad battery isnt pulling the other one down.

12.5V on each

Check the battery connections; check the ground is OK.

When you put your key in, does the immobiliser light go out?

Why did you change the batteries?

 

[Tero]

The Ground is ok
Yes immo light go out.

I changed cause the both batteries ran out. i had batteries for a few years

 

[karl2000]

OK can you check for codes?

 

[Tero]

Do you mean engine error codes ? I don’t have computer with software for it.

if this helps you, I unscrew the screw from the injection pump and the fuel does not come out of it when starting the engine

Yep. I know the immobiliser puts out a code if it's not happy.

Did you put the proper right hand and left hand batteries in it, with the opposing terminals? You didn't possibly short it out when connecting?

Might be worth checking the fuses just to make sure none have blown (eg fuel pump)

Not sure if these have a fusible link as well in the fuse box, and it's too dark to check mine now :-(

When was the last time you had it running? It was OK before the battery change?

 

[karl2000]

Make sure your fuel filter is primed as well, if you haven't already.

Before the battery change everything works fine.
I checked fuses each of them is good.
Last time it was a few days before change. Batteries ran out and Car has not electricity so I changed them . Radio , windows etc works fine but engine won’t start.
Batteries are connected properly

 

[Tero]

Fuel filter also is fine I have checked it

 

[karl2000]

Hmm, are you getting fuel into and out of the fuel filter?

Apart from that, lets see what the experts here say; I think it might need codes reading!

 

[karl2000]

Last resort you can try and reset the immobiliser (thats what it sounds like to me), but see if anyone else has any suggestions first.

 

[Tero]

yes fuel comes in and out

I will try to get the engine errors codes.
Do you know how to do it ? Obd2 interface?

 

[Tero]

How can I do it ? Reset the immo ?

Tero, if all else has failed, disconnect both batteries, leave for around 5 mins. and reconnect. The reds + live first then the blacks earths- to reduce the risk of sparking. Then see if it will start, this MAY reboot the ecu.

What's the cold crank amps of the new batteries they all 12v but new doesn't necessarily mean adequate .

Thats how they are labelled but are they actually putting that out?
