You need to check and see if the auto shut down relay is working,with the key on test the dark green/black wire at each injector there should be a constent 12 volt at each wire. if not check the auto shut down relay the relay is located on the left inner finder.
4 wires on the relay the red wire should be 12 volt all the time if not check the fusable link at the positive battery post........the dark blue/black wire is the output wire it goes to a splice and then to the fuel injectors and ignation coil and fuel pump relay and to the power supply for the ECM.....the dark blue wire goes to the ECM and is the computer controled ground circuit for the relay if you ground this wire the relay should close ( click ) and send power threw the dark blue/wire.......the dark blue yellow wire goes to the diag. conector.
with the key on there should be 12 volt at the fuel injectors if not check for 12 volt to the red wire on the ASD relay if there is power at the red wire and none at the injectors try grounding the blue wire if still no power to the injectors then replace the relay if when you ground the blue wire you then have power to the injectors get back with me and i will look up the test to test the ECM circuit....good luck
your welcome
i think you are at the wrong relay, there should not be a green wire at the ASD relay. give me the year and model again and weither it is a ram charger or ram wagon and if it is a ram charger is it a ad100 or ad150 or aw100 or aw150 if it is a ram wagon is it a B150, B250, B350.
4 wires on the ASD relay red, dark blue/black, dark blue, dark blue/yellow NO green so i am not sure what you are testing.
check you fuesable links at the bvattery also check the negitive battery post there is a small black wire on that goes from the negitive battery post it is called a power ground make sure it has not burnt into were the wires go under the battery box we see the harness get croded from the vents on the battery, the power ground goes to the ECM and is the wire the computer uses to close all the relays.

O.K john i will check tomorrow getting dark out will let u know thank's james
hello john have 12 volts to red wire,grounded blue wire relay did not close.green wire with white stripe show to be grounded. manually close relay still nothing. any ideas. james
hello john, red wire has 12 volts, grounded blue wire relay did not close.replaced relay still nothing,green with white stripe shows to be grounded. thanks james
hello john, its a 1988 ramcharger aw-100
my has a red ,green w/black stripe,blue w/yellow stripe,blue w/white stripe. green w/black stripe runs to fuel tbi's and then to coil
john it has 4 wires red, green and black, blue and white, blue and yellow
