Yann Posted June 12, 2022 Report Share Posted June 12, 2022 Hi, I tried the first start of the engine after an injector and ECU change (top feed conversion, and ECU changed for a G4X) but I don't have any fuel distributed. the setup is : Fuel pump 255l/h Walbro Injectors Siemens Dekka IV 80lb (840cc) ; 12.5 Ohms I created a gauge with the injector duty cycle as below While cranking the max reached by the gauge is 0.8 % I tested the injectors out of the manifold and they are not cycling meaning I don't have nay fuel coming to the engine. I didn't measure the impedance at the injector but they are supposed to be high impedance. The deadtimes are coming from the manufacturer's chart so I guess they are OK. I didn't fill the "short pulse width adder" table. Here is the base map I am using to start the engine: Subaru WRX V5-6 Premier demarrage.pclx Do you have any clue where the issue may come from ? It's like for some reason it refuses to send signal Thank you in advance, Best regards, Yann. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 12, 2022 Report Share Posted June 12, 2022 go to >fuel>fuel setup>injector test, then test each injector one at a time to confirm you can hear each one clicking. If they test ok then give us a log of it cranking. Quote Link to comment Share on other sites More sharing options...
Yann Posted June 13, 2022 Author Report Share Posted June 13, 2022 Hi, After continuity check of the command line of the injectors it appeared the adaptors US to DENSO were faulty. After a change the car started up as expected. Quote Link to comment Share on other sites More sharing options...
