1984 C4 injection
I just acquired a barn find '84 Vette that has been sitting for 26 years. Anyways, I have finally got to the point of starting it and noticed that the rearward(nearest firewall) injector on the crossfire is not pulsing. I have the signal(checked with noid light). Anyways, I was looking around for new injectors and seen that they are different part numbers for each....front is one number, rear is different part number. My question here is......what is the difference between the two???

When its running unplug the injector and take a fresh 9v battery and touch the terminals. Then reverse the battery and try again. Probably just stuck, and this trick has worked for me quite a few times.

If I remember correctly the front injector is 61pph and the rear is 68#
My ASSumption is the size difference is due to the EGR placement on top of the rear runners
