Hi Michael,

Don't worry about the ECU control of the fuel pump. The only thing it does is switch on the relay. If those wires had been shorting together your blade fuse would have opened. And if the relay got "switched off" your car would die right there. But the fuel pump relay can be a locus of intermittent high resistance which is probably the most documented LH cause of death in Brickboard history. Replace or resolder is consensus advice.

As for re-learning, our LH2.4 cars are all a little stumbly for the first 10 mins after a reset. The idle is typically low and the urge to two-foot is a part of the re-learning. But I don't have any LH3.1 experience.

That kit is good to know about. Many would just like to buy the Bosch flare fittings and procure the rest at Home Depot. In 1999 I made many visits to auto parts stores looking for just those adapters before I found this forum and got the advice from Stoney to grab a fuel rail at the junkyard. Talk about having the time...

Anyway I can't tell you to sacrifice your cold start valve. In LH2.4 that would be simple -- just move to a 951 ECU.
