ok so i just did a lsvtec swap into 90 sedan and i have no power coming from my ecu, as in my injectors arent getting power to spray so can someone inform me on how to correctly get power from the ecu?

 

check ur alternator/selinold fuse thats what happen to my 91 civic si.

 

i checked all my fuses and they are good, im pretty sure i checked everything and i still cant figure it out

 

have u check ur main relay? theres a fuel pump relay and a main relay under the driver side dash boad. cost about 70 doller for a new one.

 

heres a website where is can be located and what it is

i checked main realy and its good, but i am still not getting sny power to my injectors and i cant figure out why,

 

Is the ecu grounded properly?

 

isnt the ecu ground on the thermostat?, if so then yea its grounded, anything else

 

Injector power comes from the main relay. You need to check the 2 wires in the injector's plugs.

Each injector plug should have battery voltage on one wire (when the key is on). It's the same wire color on all 4, maybe yellow/black. If that's not good, check back (upstream in that circuit) for broken wiring or fuse, etc.

The ground side of each injector's circuit goes to the ECU, which switches it to ground when it wants to fire. Check continuity back to the ECU plug.

 

Checked that your fuel pump is working properly? And how is your ECU grounded
to your thermostat?

 

ecu works fine and i double checked the thermostat ground and its good so im getting new injectors now cause i finally got a pulse, but the injectors were bad
