Hello, I have a 1999 Ml430. It has a brand new fuel pump, a brand new CPS, and a new battery. It still will not start. When attempting to start it, it goes straight to auto-cranking and it does not fire. I took off a spark plug cap and grounded it with a spark plug in it to see if it had spark, and the spark is very weak. The fuel lines, when hooked up to a fuel pressure gauge, show sixty psi when cranking and fifty-five afterwards. My ML has been down for quite sometime now and I would really appreciate some help.
