Injectors not firing

Recommended Posts

Hi, I have recently done an engine conversion from a ca18det to an s15 sr20det vct. Finished hooking up everything and had my link atom wired in but when I go to start my car the injectors aren't firing into the cylinders. The fuel pump is hardwired to the battery and there is fuel going in and out of the fuel rail how ever no injectors are firing. Does anyone have a pin layout for wiring a g4 atom into an s15 loom? I assume the problem is that the ecu is not sending a pulse to the injectors but I have no idea where to start with sorting out that problem. Also, is there a way to check on the pclink if a pulse is getting sent out to the injectors? Any help would be greatly appreciated.

Just running a base map on the ecu at the moment. Not sure if that would automatically set them up. I am pretty new to the link program and haven't checked out too much of it. By triggers do you mean the pattern that the injectors are triggered to spray in? Pretty sure the cylinders fire in the order of 1,3,2 and then 4.

I mean have you confirmed your trigger 1 and 2 are correct. If your crank and cam signals are not synced the ecu wont know when to fire the injectors

Further to Jonny's comment, you can easily verify your wiring using the injector test function.  With ECU connected to laptop and ignition turned on, fuel pump turned off, Go to Fuel>Fuel Setup>Injector test. Set it to Inj 1 (2ms 10Hz), you should hear No 1 injector clicking.
