Okay, so after I finally get a new transmission to buy(another problem lol) i go to start my car and it doesn't work. It cranks and just doesn't start. I have gas, I get spark on the plugs, but don't know how much power is supposed to go to the fuel injectors. A little bit of gas leaks out of the O ring after I crank but i don't know if thats a pressure issue or it just is a leaky O ring.

I Checked voltage from the distributor and it was fine. Checked resistance on each of the injectors and they were all 14 so they should be good. Checked all fuses in the 3 fuse boxes and they were good. I'm thinking its a wire somewhere but can't be sure.

Does anyone know the voltage that's supposed to be going to each injector? If it is 12 i will try hot wiring one to the battery to make sure it works before thoroughly inspecting each wire.

Any suggestions on what to try would be appreciated, thanks for the help

does the engine show any signs of firing/combustion? if it does and just doesn't catch, i'd check both timings (mechanical/ignition).

if it's just turning over and no sign of life, i would make sure you're getting gas flow. check your spark plug wires and make sure they're in the right order.

if you're getting fuel, compression and a spark with correct timings, the thing should start, or at least show signs of hope.

as far as the voltage to the fuel injectors...i really couldn't tell you. i just know they work when power is applied to them :P i do know however that the more voltage applied opens them further.

ok this is guna sound really stupid but if you disconnected both fuel lines at any point make sure you put them back on correctly. line out of filter to the front side of fuel rail. and the other to the fpr side. i had same prob and thats what i had done. next thing if thats not the prob check your fuel pressure. just because you have fuel does not mean you have pressure. do both of those things and i bet that beast starts
