I just got done puting my engine back in the car, and now the fuel pump and my injectors dont seem to work. I know my pump is good because when i jump it with the gray wire in back of the alternator
the pump works. When i turn on the ingnition i dont hear the pump and my injectors are not working because even after cranking the engine my sparkplugs are bone dry.could i have forgotten to plug something up ? or could something have gone out while the car sat there for a few months, everything worked when i parked it there before removing the engine...
HELP! Yves M.T.L. Canada
Check your grounds on the back of the cylinder head, make sure they are connected good. I just put my engine back in and im haveing tons of trouble too ...
on the fuel relay heres what i have.
a pink and black wire hot whith the ing. on
a black and white wire with a good grnd.
a green and white wire with nothing at all ing. on or not.
if i bring current to the green & black wire the relay closes and the pump turns on but doesnt turn off.
i tried to strart the car while jumping the fuel pump but the injectors dont work.
the green & white wire goes to the e.c.m. unit could this be the problem?
the car has sat for many months without a battery while the engine was out could the e.c.m.deprogamed or gone bad because of that?
as you can see i am out of ideas to solve this problem i have to get this car running to drive it over to its hybernation place for the winter wich is right around the corner.
any help is really apreciated thanks, Yves M.T.L. Canada
The fuel pump and injectors power comes via the FP/INJ fuse . The ground for the injectors is made by the ECM so check the ECM/IGN fuse. Also be sure the orange wire going to the + battery post is connected via the plug.
