Hello all, my 93 850gle still wont start. It cranks over to start but never fires except if I use ether then dies right out. The fuel pump is pumping and I've changed the fuel system relay. I pulled the injector rail off and turned the engine over no fuel came out of the injectors. Pulled one of the injectors out turned it over again and fuel came shooting out. There is obviously something that electronically allows the injectors to open but I have no idea what it may be. A friend thought maybe the manifold pressure sensor but I can't seem to find it. If anyone could help it would be appreciated. Thanks
