With all the talk of jumping the RPM relay, I want to add something to it. If I'm wrong on this someone correct me. When you jump the RPM relay and the engine is not running, if the injectors are still in the heads (pointing into the cylinders) aren't you dumping raw fuel into the engines cylinder?? If the pump is running then it is building up pressure and opening the injectors to spray. If this is the case then not only are you going to flood the engine but you are "washing out" the cylinders which is very bad. It will wash out any lubricant (engine oil) that has coated the cylinder walls for protection. If I'm not wrong about this then I think the safest bet for anyone that wants to troubleshoot their fuel problem and needs to jump the RPM relay is to remove the injectors and place them in suitable containers...like a glass jar or something.
