Car won't start, and it's 10 degrees outside
I have a 1993 4Matic 6 cylinder that won't start. Here is what happenned right before the car stalled. I was accelerating onto the freeway, and the transmission kicked down one gear (I was going about 20 mph at that time). About 15 seconds later the car stalled. The car would not re-start yesterday, and not this morning. I checked the spark plugs, and I am getting a spark. I checked the fuel coming into the injectors (I have the old CIS type fuel injection), and some fuel is coming out sometimes, and sometimes no fuel seems to be coming out.
Could my problems be related to having kicked down the transmission while accelerating?. Also, could it be the fuel pump or relay?. What is the best way to diagnose. thanks....doug |

When was the last time you filled your gastank?
May want to throw a can or two of gasline antifreeze in there. Other than that, yes possibly the f.p. relay or the pump itself.

Car won't start
I filled up with gas one week ago, and only drove about 50 miles since. I also put 2 gallons of gas into the tank last night.
I checked the cold start valve. When I removed it from the manifold, there was a lot of gas pressure and volume, So I am not sure if I am getting too much gasoline.... |

Check the fuel pump relay (probably time to replace it anyway) and the fuel pumps. Don't know if you have the infamous MAS relay instead of separate ones (big bummer, it's pricey).
You have classic symptoms of a dead fuel pump relay, gives only intermittant current, or dead fuel pump. There are two pumps in series, if one is bad, you won't get enough pressure to operate. Fuel pressure is 4 bar, I think, maybe higher. I would also check the rotor -- they are known to crack and jump around, commonly after a sudden high rpm "shock". If it's still turning, it will give you spark, but not at the correct cylinder. Peter
