So some of you may have encountered bad relays. Fuel Pump, Throttle Control Acuator, and a few others. My 03 G35 Sedan has 4 of these small relays "OMRON G8VL-1A4T-Y" is the part number. These are the smallest relays on the IPDM. Infiniti will tell everyone they need to buy a new IPDM when one goes out. They are so hard to remove you most likely will damage the relay pulling it out, lol. The model we have is discontinued but they have a replacement that is cheap like normal relays are Osrom G8VA-1A4T-R01-DC12 here is an example http://www.newark.com/omron-electronic-components/g8va-1a4t-r01-dc12/relay-automotive-spst-1a-16vdc/dp/05M0229?ost=G8VA-1A4T-R01-DC12&selectedCategoryId=&searchView=table&iscrfnon sku=false
I had a bad relay and is still bad. To test them you can tap on the relay itself and it will click on and off repeatedly if it's bad. Hope this helps some of you not waste money.
