New year, same old problem. The 93 240 is randomly stalling. The problem is getting worse, it stalled 4 times on a 10-minute drive.

The car stalls regardless of whether it's sitting at idle, or while driving. It gives you no warning, engine just stops like when you turn off the key. Once it stalls you have to wait 5-10 minutes and it will start right up.

So far, I got a new battery because the old one was getting a little tired, and I just put a new crank sensor in. I also resoldered the fuel pump relay this summer, which cured a problem with long crank times.

I can't tell if the fuel pump is running when it cranks and won't start. I figure the next step here is to run it until it stalls and see whether it's the spark or the fuel that goes away.

One thing I can't remember is how to hook up a manometer to the fuel lines. There isn't a nice Schrader valve that I know of. Do I need to splice a T in the line somewhere?
