Injector not opening
Hello I?m new to group don?t mind the English I?m from holland.
I?m working on a zr1 1990 when I begun working on the car the client bought the car with no engine, and someone was been cutting in all the original wires. I put in a original used wiring that was cut off at the firewall, solder all of the cables. And put in a rebuild engine. Today we tried to start everything is working we have fuel on the rail, spark is there. We have 2 ecm?s, 1 off them refuses send a signal to the fuel pump, then we tried the other ecm and the fuel pump works🥳 Only thing is, it seems that the ecm doesn?t send a signal to the injectors to open them, we do have a positive on the injectors. Can it be that there is a problem with the vats system? Hope you guys can lead me to the right track, it was not an easy job 😅 |

Re: Injector not opening
Cannot be VATS as that would disable the fuel pump and spark plugs
