Scott Posted April 19, 2014 Share Posted April 19, 2014 Does anyone know the circuit for starting the fuel pump with a Syvecs on board? I'm about to email Ryan but I thought I would ask here just in case I could get the answer right away. I turn the ignition on, the relay on the syvecs loom clicks on but the fuel pump doesn't come on. I've checked the diagnostic port and B+ is getting 12v when the ignition is on, if I bridge the B+ and FP the fuel pump comes on as expected. I'm just wondering if the circuit is exactly the same as stock? I don't want to start fault finding based on the stock system only to find it triggers differently Cheers Scott Quote Link to comment Share on other sites More sharing options...

Scott Posted April 20, 2014 Author Share Posted April 20, 2014 did you find the answer to this ? Not yet, Ryan can be quite busy at times so it will take a few days for a reply. While I was waiting I checked out the EFI relays etc, everything there is working fine so the fuel ECU is definitely getting 12v. I can only assume it's one of the triggers that isn't working now, possibly the wrong pinout or a broken wire or something. Cheers Quote Link to comment Share on other sites More sharing options...
Scott Posted April 21, 2014 Author Share Posted April 21, 2014 Exactly the same as stock. Sorted the issue out, I had disconnected it for safety a while back. Once I knew which circuit to follow I found it in minutes. Pin 22A on the stock ECU plug. Quote Link to comment Share on other sites More sharing options...
