Question about 1994 Buick Park Avenue

Fuel rails/injectore removal

Started to replace leaky upper intake manifold...had everything out of the way of the manifold but the rails. Got shaky here, never fooled with rails/injectors before. After removal of bolts holding rails, how do I get rails out of the way to lift manifold?

They just pull out, replace the O ring seals on each injector before reinstalling, also put Vaseline on the O ring seals before installing them to prevent damage.

How do you remove fuel injectors from a 2003 Toyota rav4


ok now before you start disconnect the negative battery cable then relieve the fuel pressure by opening the gas cap, then remove the valve cover, then the throttle body, remove the two clamps then disconnect the wire harness from the intake manifold, then the four injectors connectors from the injectors,then remove the engine wire protector from the right side of the intake manifold,remove the EGR valve and the EGR valve pipe,remove the top fitting on the fuel filter and remove the fuel line from the fuel filter,move the brake booster vacuum hose from the intake manifold disconnect the fuel line from the fuel rail,remove the fuel rail bolts, then remove the fuel injectors from the fuel rail,and when replacing the injectors always put new seals because the get hard and may not seal properly

Vehicle will not start after changing the upper intake manifold.


You should not have to bleed the fuel system. If everything is functioning properly it should bleed the air automatically just by cranking over for a few seconds. is it possible you left an electrical connector unplugged? It sounds like maybe the injector harness or one of the coil connectors is not plugged in. I would check all the connectors you can to make sure they are plugged in and fully seated.
