What is the voltage on both pins at the injectors?
Wire breakage in the harnesses and connectors is a big problem on these cars..... If you have 12volts on both sides you have a short........ you should see 12 and 10

I think you are right FR....
From what I have read the KLR does not affect injector firing Also the main power transistors can develop cracks at the soldering joints.......so you may be able to re-solder to solve your problem..

i was just looking at a manual i have on cd its for a 944 turbo its says when testing fuel preasure you should get 2.3 to 2.7 bar when jumping the relay they didnt say to remove any vacumm line so if thats the case then my regulator is working right?
