I mean yeah. a '73 T3/AT ECU (for example) wouldn't be *right*, but would help troubleshoot whether the fuel pump circuit in your ECU is or isn't the problem. >> I do have a T-3 "D" brain around. I was saving it for when I get the rest of the parts (fuel pressure regulator, and matching "D" MPS) for my wife's car (or my Notch ;D). I've got another T-4 "B" brain coming from Cali in the next few days, but I'd kinda like to know if this one is dead. I can get the pump to run if I ground the #19 wire (attached to the car), but if I plug it in I get nothing. I've double checked the connections, and wires and relays, and they're good / connected correct / and have continuity. About the only thing I haven't tried is grounding the relay terminal to see if the front relay will energize, although I suspect that grounding wire #19 does this. :O Bob 65 Notch S w/ Sunroof and IRS 71 Square, now a 2 seat Roadster, pics can be seen at; http://volksrods.com/forums/index.php?showtopic=2977 and now has a 2.0L t-4 with D-jet FI engine transplant, just finishing up the details. : ) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
