Hi guys, been working on this 00' A4 1.8TQ w/ Tip. for a few months now. Yes I'm an idiot cause I believed the young kid who swore car ran good till fuel pump died, but that's another story. Put in a used, exact same, ECU I ordered from ebay since other 1 was fried. Fuel pump works good when I run + to fuse 28 or manually press in contacts to fuel pump relay w/ ignition switch in on position. I have + to fuel pump relay & relay clicks when ign. swtch is in on, but no fuel when cranking. Also new OEM fuel relay. New OEM ECU relay & have + to that relay but not getting to fuse 29. Put in new crankshaft sensor as well. I hate not knowing if this new used ECU is bad & was hoping some1 nearby could help me out. I have new Hex-Com-USB from Ross-Tech & will help any1 who is in need of it anytime if they can help me. I was told to plug it in a working car & see what happens. I have Bentley for A4 B5 & ELSAWIN 4.2 for every VAG car. Please let me know ASAP if u can & will help. I'm in Suffolk county, Shirley. My name is Jimmy & my cell is 631-514-9055. Thanks.
