injectors not pulsing
We went in to this swap blind my son and i are spent on the injectior ar still not working. we swaped 12a-13b 1985. if any can help us please do so far we have done a lot of stuff but no fuel. the fuel is in the rail if appears that all the wireing is hooked up. 12 v all over the place when my son gets off work i will have him do pics of the ecu and engine area. at this point just to hear it start wound be great. thanks to all

If the 85 injectors work like the second gen (which I would guess they do), you should have 12V to one side of each injector. Then you will get a pulse on the other side (as the ecu opens the circuit to ground). If you are not seeing pulses, the injectors can't work. If they are not working, check the signal from the coil, check the grounds at the ecu, you should have zero V.
Check the factory manual for the pin numbers at the ecu to tell you which ones are the ground. Find out where the ground wire(s) are for the fuel injection system and make sure they are connected well. |
