Are you sure you aren't getting an unknown vacuum signal to the shut off valve, shutting down the IP?

I know I'm having vacuum issues because my door locks are rock solid they will not push down! What I need to get straight in my head is can the original shutdown issue be caused by the aforementioned vacuum issues? Will the engine actually shutdown do to vacuum problems? Or is it an air issue in or around the pump somwhere?? ...

Yes, if somehow vacuum is getting to your shut off valve, it will shut down. Something is wrong with your door locks. I would remove the brown line from the shut off valve and rely on the shut off lever under the hood for a while and see if that resolves your problem.

Oh while running drivers door lock locks fine, other three doors hard and spongy. So I guess the question is now? Where exactly does that leave me? |

Ok, I'll accept that designation and request that the moderators replaced 'Registered User' with 'Genuis' under my name.

That is easy to trouble shoot. Disconnect the Vacuum Line at the Vacuum Shutoff on the Fuel Injection Pump and plug the vacuum line end you disconnected. If you can start and drive with out the problem showing up then it is likely you have some vacuum issue. Altenativly you can disconnect that Vacuum Hose at the Vacuum Shutoff and connect a Vacuum Gauge to it. Start the Engine. You should be getting no vacuum reading. High crankcase/blow by pressure can push the Vacuum Shutoff towards the shut off position. Make sure the vent on the valve cover and the related tubing are not obstructed. You can start your Engine and remove the Oil Fill Cap and see how much blow by chufs out.

If it runs fine with the brown line removed it is highly unlikely that it is internal crankcase pressure activating the shut off valve. It is likely an errant vacuum signal in the brown line.

A bad injector won't shut the engine down. Try driving it with the oil fill cap off to relieve any crankcase pressure.

OK//
Did that.. No change just a big mess... I'm stumped! I can make it bog down if I lay into it that's when it really starts to get bad I would still go for fuel supply but I've had that auxiliary tank hooked up and there was definitely no air getting to it then and I had the same issues. I just don't know these cars are crazy....
