I see, thanks. Do you know if the injectors are getting a pulse?

That i do not know and not sure how I would check
Expert:  Super Mechanic replied 6 months ago.
Normally you can use a special adapter on the harness but there is a way to check with a low voltage test light, (LED). You can test by back probing the injector control wires one at a time just to see if the light will blink. Test light hooked from BAT + to the injector control wire. I have a pinout attached of what each wire is for..

Just to be sure, does the security light come on with just the key on? (bulb test)
Customer: replied 6 months ago.
yes it does
Expert:  Super Mechanic replied 6 months ago.
Okay, thanks. I should be on most of the evening, see how the pulse is to the injectors. It sounds like it may be shutting the off.
