so - if you hot jumper the pump - does the car run OK?

fwiw - i had a similar problem awhile back on an engine that had sat in storage a long time - turned out that 3 injectors were stuck - it had the same start-die symptoms you describe

But using terminal 20 on the DME plug-in per ECU Doctors, the fuel pump did not work. This method goes thru the DME relay, I think my new relay is bad. What do the wizards at Pelican forum think about my findings?

All of the problems with this car turned out to be at the fuse panels. Bad connections from a VR problem I had a while back, things got a little toasty I guess. New fuse panels should fix the problems. Parts are on order. I sure will be glad to get this car going again and staying running. When I do get it running I am going to wring it's neck for being such a pain in the ass for so long!

I know you told me Joe Bob, I always had good voltage at the DME and DME relay during tests, so I thought that power supply was OK. I sure got a bunch of new parts on her. She has a name now, after a car or truck leaves me stranded on the side of the road like "Gudrun" did two weeks ago they get a name. She has been named after Heinrich Himlers daughter. Not a very flattering name at all. As an adult she worked to free Nazi war criminals.

VR is voltage regulator.
