Injectors
Hello everybody and Happy new Year.
I'm this weekend going to replace the Fuel Injectors in my 89. I think one or more is not working, maybe clogged. I also want to make sure that they are all getting a signal to fire. Can I use a multi meter to determine if the injector is receiving a signal to fire? If so how? Thank you

If you want to see if they are firing, put engine at 1500 and unplug each injector one at a time and see the difference. No tools Bubba way to check.

Basics. Without a bench flow.
Another method remove the EV1 connector.
Ohm every injector. good condition Ohms should match.
If OE 16.0 - 16.2
1 - 2 Ohms. Higher or lower. warning sign.
Pull FP fuse. Key on. Crank. Check voltage on every EV1
Lastly reconnect. start. Pull one EV1 monitor.
idle should drop. Unbalanced.
Reconnect EV1 idle should restore very smooth.
Monitor the remaining 7

Thank you for the response. I have Ohm checked the injectors. They are good. But, I am replacing them. I have new BOSCH III injectors. I just wanted to see if I can ckeck to see if they are getting a voltage. Thank you

TunePort90,
My bad. D3? Offset battery voltage in the tune? I have used Scott Hansen to program my chip. Is that what you are eluding to. I have TunerPro RT. So after I change the injectors and fuel pump. Get a run on TPRT and then send that to a chip tuner like Scott?
Thank you
Joe
