Hi,
I am newb here so please be patient with me. I bought my son his first car a 1988 300E that has only 105.000 miles on the gas engine. It ran great but recently he let the gas tank run very low and now it wont start. I have no spark at the distributor cap and no line voltage power at the coil. I tested the fuel pump relay and bridged fuel pump relay contacts #7+#8. The fuel pump ran OK the next step according to ALLDATA was to check for line voltage power at fuel pump relay contacts #9+ #11 with the ignition switch turned on. This is NOT OK there is no voltage. The next process is to repair the open circuit according to the wiring diagram. The ALLDATA online logic diagrams are very difficult to read clearly the terminal numbers etc. I need some help deciphering what the next step is.
