Help!! 320d turns over but doesn't start

Recommended Posts

Hi

Im actually new here and after some help. Ive got a 2002 320d which turns over but doesnt start, however if I jump start it, it fires up straight away. The only time it has trouble starting is mornings or if the car has not been used for like 4-5hours. It starts up straight away if i try just after switching it off.

Ive changed the battery and checked fuses under the bonnet where the ecu is kept because from what i've read online the fuel pump fuse is located there. All fuses there where fine. Before I start spending stupid amounts of money to find the problem I wanted to know if anyone has had this problem and been able to find the solution to fix it.

 

Thanks in advance

Is the replacement battery brand new and up to spec CCA wise?

Is it a recent problem? Cold weather starting problems usually point to glow plugs or injector faults

Ok so a little update which had left me totaly stumped...

I had it on a computer yesterday to get the fault codes read and this is what I got

4212 Glow Plug, Cyl 1

4232 Glow Plug, Cyl 3

4242 Glow Plug, Cyl 4

43F1 Electric auxiliary Heater

4B90 Rail-pressure monitoring on engine start

4222 Glow Plug, Cyl 2

4630 Rail-pressure plausibility pressure-controlled

 

So on the back of that I changed to glow plugs today (mission of a job) but got it all out and back together without breaking or losing anything, BUT when I went to start it, it just turns over and doesn't start up. So thought i'd try jump start it (which use to work before changing the glow plugs) but that didn't work either.

All fuses seemed fine, I also checked voltage across the battery prior crank (12.6v) and on crank (11.2v).

 

Does anyone have any advice on what I should do? Please help, im stuck without my car

Thanks in advance

Is the fuel filter fitted the right way round?

My advise is to check your injectors . If they don't spray a fine mist you will have difficulty starting when cold.Next step would be to take compression test to ensure your compression ratio is correct and make sure your glow plugs are working. A diesel motor will run if it has compression and fuel. If your injectors are dripping it could damage the motor or even burn a hole in the pistons.
