Grant GP AUTO-TECH Posted November 11, 2012 Report Share Posted November 11, 2012 Hi guys, just fitted a plugin to a 97my R33GTS-T and the battery went flat, charged battery checked all outputs were set up, tuned vehicle. Next morning another flat battery. Found the fuel pump is on all the time-has a stock pump and is almost silent and very hard to hear in the workshop. Went to loom header and found no wire on pin 18. Anyone else come across this one? Will start looking for wire that must somehow be earthed on another pin in the vipec. Quote Link to comment Share on other sites More sharing options...
Simon Posted November 12, 2012 Report Share Posted November 12, 2012 There must also some form of back feed as the fuel pump should loose its power when the key is turned off. So even if it had a permanent earth it should switch off with the key. Quote Link to comment Share on other sites More sharing options...
Grant GP AUTO-TECH Posted November 14, 2012 Author Report Share Posted November 14, 2012 Yeah Simon you are right, after I removed his sub box amps and other shit to get at the fuel pump relay it had constant power. The no pin 18 is just because I am old, blind and can't count. The isc also had no power to it for some reason. I thought I would take the easy way out with the fuel pump relay and rewire it to the rear wiper ignition power wire-fixed one problem and caused another, when the turbo timer was used and the key turned off the power to the wiper motor also turned off so the engine slowly died so just ran a wire inside up to the power supply to ecu, also powered up the isc to same and all works good. Tomorrow I am taking the car to a priest and getting him to carry out an exorcism on it. Quote Link to comment Share on other sites More sharing options...
