I have had problems getting the car to turn off. I also have had problems getting the door locks to work. I know I am getting some vacuum so i don't think it is the pump but I will be checking later today with a mityvac. I took it to my mechanic and he said it was the fuel shut off valve. I ordered one from diesel giant and replaced it and viola.....nothing turned off. I thought it might be the booster, but again, i am not having trouble getting vacuum. SO I am still opening the hood to shut it off.

What would be the next step in figuring out this problem?

is the klima off when you are attempting this? locks unlocked?

the doors are unlocked. A few days ago I was working on the switches to my windows in between the seats and after I got down working on them, the door locks worked and the car actually shut off at the ignition. The next morning, it wouldn't work again.

I thought about disconnecting everything to my EGR since I don't have to worry about smog in arkansas.....we don't have any type of standards for that stuff. Maybe, with that taken off there might be more vacuum to be used....

it turns out that when the mityvac is put on the main hose I am getting around 20. I also found out my door locks are leaking bad somewhere because I can turn off the car when I hook it directly up to the main line but if I put it through the 4 rubber joint I can't it to turn off.

Next step get new main vacuum line and start looking my doors the old fashion way....
