'91 350SDL overboost protection switch delima
I just replaced the crossover solenoid (over boost protection switch MB part # 001 540 86 97) on the left fender wall and still have no boost. Apparently the old and new switch still think that there is too much intake manifold pressure (boost) from the turbo and they shut down fuel at the ALDA. Without hooking the car up to a computer and pulling codes, how can I diagnose the pressure switch sender on the manifold? If I disconnect the single wire from the pressure switch sender on the manifold the crossover solenoid still cuts off fuel. Additionally the crossover solenoid gets very hot when hooked up.
Any suggestions? Driving without the turbo gets old fast. Mav
