HELP! Really odd problems...

[TighTheChevyGuy]

so where should i have put the grease?? and also, the injector problem persisted on the passenger side, so i swapped the clips, problem moved to the driver side. how do i tell if its a bad clip or something else??

between the module and mounting base in dizzy. when you say clip you mean electrical connector?

 

[TighTheChevyGuy]

yessir. thats what i was referring to.

it would probably be very wise to do a continuity test of feed and ground switching wires on injectors to eliminate bad wiring as the cause. if the injectors wiring is good then the ecm must be the issue.

 

[TighTheChevyGuy]

please explain that procedure in more detail as the ECM is still under warranty and id like to replace it before that expires

 

[SunlitComet]

pm email address for wiring diagram.

if its in haynes manual, ive got it. how do i go about doing a continuity test???

 

[SunlitComet]

well make sure your connectors are clean. ensure the red and white wires on connectors are receiving the same voltage when key is on. trace the other two back to blue connector i think on the ecm. and continuity them individually. might even measure the voltage of them at ecm with key on using the same body ground for neg probe of multimeter to see what voltage makes it thru the injectors. if measurements are the same roughly and indicate no broken or loose wires(wiggle the engine harness a bit to make sure)the ecm connectors or ecm has to be cuasing the issues.

 

[TighTheChevyGuy]

so measure at the electrical connectors on top of the injectors, then again at the electrical connector on the ecm? and if those are the same, all my connections in between are good (thank god) and its gotta be the ecm? correct?

 

[SunlitComet]

something like that.
