I m having issues with my ML320 not starting it cranks, starts 2 seconds then dies, I have read that it could be the immobilizer my question is how can I confirm it is the anti theft system?

 

You must scan for codes in every module.

 

Welcome TeacherRiveron,

There is a red led on the dash -left side of the radio.
Check to see if the red led blinks once when you turn the key to #2 position.
This relates to the Drive Authorization System DAS (Immobilizer) as an indicator.

Please update your user cp info:

 

Thanks for the reply, I turned the key to #2 position and the red led light blinks not only once it is constantly blinking.

 

Teacher,

If you wish some solid help, you need to follow the replies provided to you.

1) Scan (as advised by Dundee), and post any codes.
2) Update your user cp info.

There are no shortcuts, unless you want "needle in the haystack re$ponse$", and throw $$ at it.
Right now, it could be a number of issues.

EDIT:
To answer post #4:
LED should ONLY blink ONCE. If you have spare keys, fob, try them. Only those keys which blink once can be used to start the truck.
Note: If none of the keys blink, you have an $$ problem on your hands.

 

Before this ordeal that the SUV wouldnt start there was a hesitation when accelerating the car, the codes were P0137, P0170, P0400,P0115,P0105,P0130

changed MAF and cleaned throttle body as stated by the mechanic after that it was sparkplugs and coils, so my car would start up fine then after changing the air filter, changing the MAF and cleaning the throttle body Im stuck with a crank no start issue, the car starts for 2 seconds then dies. thanks for your help

 

You replaced all those parts and you still have the same problem.

That is why you need a scanner.

 

I scanned it before changing
parts, thats why I replaced the air filter, MAF and cleaned the throttle body. I wasnt able to change coils and plugs because the car did not start back up

 

It blinks continously not just once

 

I have only one key, and the red light blinks continously, what kind of $$$$ is it?

how is it repaired?

 

Khomer, as you can already see, he ignored your request to update his profile and my suggestion that he scan for codes.

He only wants answers and can't be bothered to answer our requests. Why should we continue?

 

What are you talking about man! Im
totally new here I didn't know I
had to update my profile or how to use this blog and as for the codes I did post them. Thanks for your help anyways

 

He gave you instructions on how to update your profile which would have taken 1 min. and you ignored it. Plain as that, MAN.

 

Plain as day, after post #10.
