1986 Benz 560SEL - Went dead during idle and wont restart
I have a 1986 560 Sel and it was running at idle for about 15 to 20 minutes and all of a sudden went dead. I attempted to restart it, and it tried, but would not restart. After several attempts, it would not even try to start anymore, it was just turing over as if it were not getting any gas. I had it towed to my house and then checked to see if it was getting any gas.
Prior to this happening, it had been idling very rough and I changed the spark plugs, checked the distributor cap and rotor, changed the gas filter and was getting ready to place the wires this weekend. After changing the spark plugs and install a new fuel filter, it ran a little better, but it was still running very rough. It would run and idle pretty good sometimes, but during acceleration it was obvious that there was hesitation and a loss of power.
After having the car towed to my house yesterday, I checked to make sure there was gas flowing from the rear and at the fuel distributor. When I turned the car over, there was very good gas flow. I'm not a mechanic, but I'm assuming it is possible that the timing chain needs to be replaced. The car now has about 170K miles on it and don't think the chain has ever been replaced.
Also, prior to cranking the car before it suddenly went dead, there was a very noticable hesitation before the car was cranked and running. I think that was a sign of timing issues, but then again, I'm not a mechanic and have very limited knowledge of symptoms of mechanical problems.
I know it is getting gas up to the fuel distributor and even sprayed to starter fluid, but it did not even attempt to start. I assume that it is the timing chain, or possibly the ignition modulator or something affecting the fire to the engine, since it is obviously getting gas.
I'm on a very strict budget and do not want to just throw this car away and try to get another one, so any help and guidance you may provide will be greatly appreciated.
