Hi, I was going around a corner in my 93 w250 auto, when I hit a pothole and the voltmeter dove to the left, the motor started sputtering and lost most of its power. I was trying to catch a plane so I just kept it going, made it about 2 miles and then it died all together. Had it towed home and haven't been able to get it going since. any suggestions?

 

FSS needs 12V. Check it.

 

Yep, start tracing voltages, pothole got it started.

 

well, I took the plunger and spring out of the fss, got a couple chugs after bleeding the second injector, fired right up while bleeding the 3rd.

the plunger shaft was quite worn on the one side, the rubber looked good but it's out of there and the motor runs fine again.

the worst damage seems to be to my finger where the dipstick bracket screw ripped it open.

Thank You
