damn . problem is back continously opened injector plz help!

[People16vT]

me and a friend resoldered all the output section and resoldered the odd looking solderings to be sure all is correctly soldered with a good welder and tested back on the car

injectors keeps grounded by the ECU when On
a friend told me to get the static electricity off the board buy grounding all the pins together with the ecu disconnected didn't fixed the prob

now im thinking about a sticky FET driver that i have to test but i dont really understand how to test it and i made a thread in the appropriate section of the forums

i took my DVOM and saw 9.9v between the 2 pins at the injector harness while i see 12.6v between the inj harness + and body ground when the ecu is on

redid the continuity test with the body to be sure nothing shorts out anything and everything is okay


i ask for testing the FET because i can'T really get into electronics shops because i work in the day and the closer shop is at a 30mins car ride
