I have a 02 s10 with a 4.3 l I have fule pressure and spark no start I tried checking for paulse but all wires to the spider injector have 12 volts and have good compression I am at a lost please help
this systems fuel injectors are ground side switched so you will only have 12v on feed wires with the injectors firing. so it would be 12v & ground only during the firing event. Are you have a no crank no start condition or a no start condition? or even a start run stall condition?
It will start with starting fluid but dies as soon as its gone when I disconnected the harness I got paulse and reconnected it now I have paulse but still won't start cranks really good but no start has 59 psi key on and 65 psi during crank I am so lost
