Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello. Most times this is caused by a weak fuel pump. Have you replaced any parts or done any testing ?
Ok so get a fuel pressure gauge and install it at the passenger front of the fuel rail. When you first turn the key on it should prime up to 50 psi + tell me how long or how many cranking times it takes to build pressure.
Understood , are you able to get a fuel pressure gauge and do as I suggested ?
ok that tells me that it very well could be the ignition switch. do you know how to do wire testing or will you have it taken to a shop?
ok i will opt out.
Hi Doug, my name is***** you still like some help with this problem?
Ok, can you explain a bit more about the no start? Does the starter crank the motor but the motor won't fire? Or does nothing at all happen when you turn the key?
I noticed previously that you said the ignition switch was good. Did you replace the switch?
