injector flush

So i have tried twice to flush out my injector,the first time i tried tapping in at the fuel filter and turning pump off,of course this is being done with the injector flush machine,proceeded to start car and had a crank no start.
The second time i tried to do the flush i tapped in through the regulator quick disconnect and blocked off return line then shut off pump,proceeded to start car and had another crank no start,has any one ever done a successful injector service,and if so how is it done?????

Successful? Yes. Remove the injectors, box them up, and send them off to an injector cleaning service.

How did you shut off the pump? Did you pull the fuse or relay? If so, that fuse or relay also runs the injectors. You need to pull the electrical connector to the pump that is by the back of the fuel tank.

i shut off the pump by disconnecting the electrical connector at the pump

:iagree:

The pump and injectors share a fuse and probably the relay, remove either and you lose power to the injectors.

There's some small screens in the fuel inlet to each injector. They can be removed and cleaned, and it's a tedious task.

There's a few pics in this thread somewhere; I can't link the pics; I'm banned.
