2G injector circuit malfunction

p203

anyone had this problem? My car cranks with no start. The thing is I have pretty much changed everything. I have new vic 2150cc injectors, with new clips and resistor pack delete. I did notice tonight as i was cranking the car the p203 code came up. While checking ohms on the injectors i noticed my return line has a leaky fitting so I will change that out tomorrow and give it another try. Anyone have any ideas on these issues? I had a friend listen to each injector while cranking and he says each one sounds like its working. every now and then it sputters like it wants to fire.

is there any way i messed up on some wiring etc common need help

You are going to have to tune them in. Why so large? 35R still? Getting spark? What all did you change when you say "everything"? We are going to need more information if you expect us to help.

Awesome some help. It's a built 2.0 manly tt ibeams e85 piston kiggly brace kiggly crank trigger 1g head s3 cams kiggly beehives etc. jmf drag mani 1g nt tb. Gt35r, fic fuel rail fic 2150cc inj 450lph etc. I know most of that doesn't matter but it's not a question of are my injectors too big it's that I have a cell and no start.

check ecu...if everything physically inside the engine bay checks out, ecu injector drivers would cause this.

ok i have a bunch of new tests done and it turns out i have two bad injectors and number 3 and 4 injector wiring has some sort of issue. 4 is seeing high voltage higher than 1 and 2 and 3 is low. must have some wires mixed up there. also i have two injectors that do not work at all, I can't even get them to trigger with a battery source. worried about that for sure so I will be calling fic to see what they have to say about that.

If you tap the injectors(quickly, dont hold it on em!) with a 9v battery and dont hear a click then you've got stuck injectors or open injectors. Those are priiiiiicey too. I would def call FIC
