ML430 will not start unless engine is cold PLEASE HELP

Racerx18691 · 10-06-2009, 11:36 PM

I have a 2001 mercedes ML430 won't start unless engine is cold. I was told this might be a crank shaft sensor. Is there another possible reason for this problem and can I replace it myself? Please tell me where it is located in engine. THANK YOU

CRANK SENSOR. IT HAS ONE BOLT AND IT IS ON THE BACK OF THE ENGINE ABOVE THE FLYWHEEL.

i'm experiencing the same prob...just died sun. while setting in the drive runnin wouldn't restart till i let it set for a few minutes...thought it might be the fuel pump...let us know if the crank sensor is the problem!

I will let you know. It might be 2 weeks though because I am disabled and short of money. But as soon as I fix it I will let u know. Thank you to all who responded.

The first time it happened to me it started after 20 minutes, then took longer and longer. When it is hot it takes over 5 hours for my money sucking ML to start. I have put over $10,000 into my ML and only has 80,000 miles. What a money pit. Will NEVER buy another mercedes that's for sure!

Crank sensor is the easiest culprit to pin down here.

I had the same problem on a 99 ML320. I replaced the crankshaft position sensor ($150 at Autobahn) and problem gone.

Here's a link on how to change it.

have u had lots of problems with ur ML as well? I have a list a mile long of crap gone wrong with it in less than 40,000 miles. since it was SUPPOSEDLY certified

LeviDenim · 10-10-2009, 08:57 PM

Rock Auto has the one pin connector lock or two pin connector lock version at about $80. I got mine from the dealer for $97 two years ago.

However I see that autohausaz.com has the Bosch for the ML for $42. That is a bargain.
If it is the two pin connector lock then look under ML 320 or call them. That one is $54
and is also Bosch. Shiping from AZ to CA is two days. Add an oil filter and it is free shipping if the order is over $50. If you need the two pin version
then it will be over $50 and you won't need to add a filter for the free shipping.

Racerx18691 · 10-14-2009, 08:50 PM

did u know there is a recall for the power steering?

LeviDenim · 10-14-2009, 08:56 PM

99% of the time the pump is not replaced unless the recalled part leaked so badly that
the pump was damaged. It is things like clamps, hoses and seals that were recalled.
Our third recall for more an improved recall just came a few months ago on a ten year old truck.
