I tried jump starting a mersades suv with my honda crv and nothing happened?

Will this do damage to my crv? Side note honda crv is gas mersades suv disel

A diesel requires more battery power to turn over.
Let your CRV run a while to build a charge in the SUV battery.

It won't damage your CRV. Try hooking up the cars again, and make sure the CRV is running for a little bit. This will charge the battery in the Mercedes. When you're ready to start the Mercedes, take the CRV up to about 1500 to 2000 rpm's and start the Mercedes. Also make sure the connections on both batteries are clean and connected correctly.

Try the same as above and rev your engine a while but I connect the red cables the the positive terminals and the earth cables to the chasses, try it that way, Hope this helps
