Re: 90 300E WON'T START-M.B.DOC HELP

I desparately need your help.

My car cranks but won't start either cold or hot. Once I add few ounces of fuel in air intake, it starts & runs on load till I shut down. I ran it more than 45 minutes. But, once I switched off, it won't restart.

I have replaced fuel accumulator. My both fuels are running. MAS relay & OVP are okay.

My initial thoughts are: fuel filter, pumps & ignition system are working.

Question: What else should be checked which can cause restarting problem?
Hi

You may be experiencing an ignition problem, try inspecting the distributor cap and rotor first. On the cap remove the coil wire & look where the boot bottoms out. You may notice a carbon ring running around the perimeter on the center terminal. When the build up is excessive it can create rough idles and or hard/difficult/no start issues. Another problem may be the ignition coil itself, a basic visual test displays voltage output but it will not help you determine if the coil has maximum output. A low budget secondary voltage tester can help you determine maximum output, you should be able to purchase one of these little gems from your local parts supplier.
