HELP MY CAR WON'T START! The car is a 1986 300E with the L6. The car ran fine before i replaced the head gasket, but now it won't even start. I have spark at the spark plugs but the color seems to fluctuate between an orangy color and a bluish white, I also have fuel pressure going into the fuel distributor and fuel at the injectors. The timing is correct at the crankshaft and at the cam with the crankshaft at 0/1 and the head at tdc with the cam mark lines matching;

and when i try starting the car the engine starts to fire but just not enough to actually fire up. After trying to start i pulled the spark plugs and found a little gas on them and found they were a bit burnt.

I am wondering if it is one of two things; 1 the ignition coil is not putting enough spark out or 2 i'm running too lean. Either way i don't know how to figure out the problem even with my mercedes owner's bible. Any help would really really help.

This is the second time i'm posting this, i checked the intake hoses at the bottom of the air inlet and they are ok.

 

why did you replace the head gasket ?

 

I replaced the head gasket because there I was losing coolant out the tail pipe. Also the coolant was mixing with the oil and i found a large amount of coolant in cylinder number 6. I took the head off and found that the gasket had blown in the common location for this car around cylinder 5 and 6 between the oil and cooling passages.
