Yeah, that Pierburg pump I believe was for the later model's(different connector)....3.6 took the 040.  My pump ran when I put 12v to it in the trunk,I'm just not getting voltage at fuse or relay which I'm guessing is the issue.   Still haven't purchased the Fluke or Powerprobe, and since my $7 harbor freight one has a bad display, was just using a test light.....but did get it to spark up with starting fluid, so we've got ignition.  Before I parked it, it wouldn't start with the pump attached to a separate battery so am guessing need to find the bad wire/whatever is causing the no voltage at fuse/relay.  Both flywheel sensors are good, but just for good measure, swapped with OEM one's off parts motor that ran when pulled which also tested good.  Swapped ECU already also just to test.  Attached new ignition switch also just to rule that out....Need a real tester.  Gonna have some free time soon, so will either buy/borrow a better test unit with long leads to try and find the problem.  Leaning toward bad wire somewhere, but if anyone's got any input...great.  I enjoy looking at wiring diagrams about as much as I like tax forms, and it's tax time....Ha.  Hope all's well, Tom
