Have you tested out the fuel pump? check for plugged fuel filter?
plugged fuel lines to the fuel rail, injection pulse at the injectors? power to the fuel pump relay? grounds needed to make certain systems work must check those also. get a wiring diagram of the fuel supply system and back trace all the wiring and see if you have power and ground and signal.

Why is there no power coming to injectors


What kind of vehicle. Most deisel injectors are operated under pressure and not electric. If no fuel to a diesel injector you may have a lift pump issue in the fuel tank

What is blocking the fuel from getting to the injectors?


I'm not a professional mechanic but the fuel pump does that and it has to have a clean fuel filter to do it effectively.

My 2001 Saturn, will start but not stay running. We have checked the fuel pump and all fluids. Did a compression check this morning, fuel injectors are not injecting fuel into fuel rail. Why is engine...


You said, 'fuel injectors are not injecting fuel into fuel rail' but it's my understanding that the fuel rail gasoline is supplied by the pump, and the fuel injectors just pulse to allow fuel to get to the cylinders. I would check out the fuel delivery problem further. Check for pressure in the fuel rail that is within specs.

If not, then the pump or fuel pressure regulator may be the problem. Check the fuse for the fuel pump. If good, then the pump may be bad in the tank.

Good luck on this.

FUEL INJECTORS WON'T LET FUEL PUMP OUT


Check your fuel filter and see if fuel is getting through it. You will know whether to look forwards or backwards after looking at the filter.

If you have the switchable gas tanks check the switch. Usually one side will always work, but if it came apart inside it may block the lines.

Since you have pumps at the tanks you should be pushing fuel, not like a diesel that pulls fuel. I would say a TPS (throttle position sensor) could be bad as it tells the injectors to let the gas in, but you say the injectors are dry. When you test, block the TPS open a bit or test for fuel before the injector rail.

Need step by step instructions for fuel injector replacement for 2001 mitsubishi eclipse. hooked up to computer and said injector in number 4 bank needs replaced. can't find instructions on how to


First and foremost, understand your working with a highly flamable fluid here, make sure engine is cold, that being said, what you have to do is remove the fuel pressure(very important), then the fuel rail. All injectors are going to be on that fuel rail and will all have to come off at the same time. Be very careful when pulling on the injectors that some o-rings don't fall into the combustion chamber. remove the lock holding the injector in place and remove it. to install the new one, simply follow in the reverse order. make sure you follow the instructions given to you by the new injector on how to intall. On some you may need to lubricate the o-ring so it installs easier.
