Same problem different car
I have been out all night installing a new fuel injection head on my 560 SEL. Before the car would start after cranking for several seconds (seems more like minutes). When it did start the car idled very roughly, and any pressure on the gas/air pedal would would result in the car shutting off. So I replaced the head as my local tech suggested, now it won't start at all. I can hear fuel at the head, and the car will fire IF I let the pumps run for a minute or so. I checked my OVP fuse it is ok, however the car has been jump started several times. Should I replace the OVP, or do I have a mixture problem.
I am going to the dealership in the morning, they are happy to help me because I went to UTI. Any help here would be appreciated.
