Hi I would check under the hood to see if your engine wire harness got wet do this with the battery disconnected, remove the stud from the harness connection and inspect the big wire also open up the black connector and see if any of the wires have begun shedding their insulation, also remove the fuse panel and find out where the smoke came from if it was burning you will find it , for a relay to short it may have a bad ground or it got wet the most likley scenerio is water dripping from the blower assembly you can see this blower if you close the fuse panel wood cover and look up you will see a plastic grating this is the bottom of the blower and if you look carefully around where it comes through the firewall leaks should be evident to fix the leaks remove the blower assembly and get some strip caulk and install on the sealing area, I would also get a fusse/relay prinout from 928gt and verify that your fuses and relays are in the correct positions and are the correct components,Stan

The only place I could find water was in the cowl. I just searched for pics of where the cowl drain is and I'll go check that out. I couldn't find it feeling around last night.
The fuse/relay diagram 928Spec has isn't exactly correct for an 84 Euro. I've sent a couple corrections to DR. I've been trying to figure something out from the WSM wiring diagram, but I haven't come up with anything other than locations it could have shorted out.

All 4 relays that could keep the car from starting were bad. I replaced the "electronic ignition" relay today, hooked up the jumper cables for a minute and it started right up. That is one of the relays not on the 928 Specialists chart. The battery was completely dead today so there is probably a pretty big drain somewhere from water.

After about 30 minutes of trying to get it started, we gave up. The relays are all functioning. The car cranks, the fuel pump runs, but the injectors don't fire. I couldn't find any water near the panel. After we gave up trying to start it, we pushed it down a hill and around the corner to a well light public parking space along a main road. We're going to try to push or pull it home tomorrow.
Something is preventing the LH from firing the injectors. I think either it's not getting power or it is malfunctioning. If the LH doesn't get power, I don't think the fuel pump should run. Any ideas?
Dave, the relay that was in the fog light space is burnt on one of the coil contacts. There has been no smoke since I pulled the relay even though the smoke was coming from behind the panel.

Check the injector FUZE. I think it's #24(?). The fuze gets hot and 'shrinks' causing it to lose contact. Had that happen to me on the road and it was a total PITA to figure out what was wrong(cause the fuze is not blown, it only melts a little and gets a little shorter in length!).

H, I think it's biting me already. I drove the car into the garage today, took the key out... and it kept running. I tapped the gas and it still reved. Reinsterted and removed the key a few more times. Finally I turned it far enough to kick the starter solenoid, then removed the key and it stalled. I hopped out and went to the back of the car. The fuel pump was not running, so its relay is operating correctly. I disconnected the battery and left it for now.
M21, The only fuse that has anything to do with the car starting is the fuel pump fuse, #13.

"M21, The only fuse that has anything to do with the car starting is the fuel pump fuse, #13."
OK, 13 it is then(i really wasnt sure what number it was), in my 83 the fuze got really hot while i was driving, and the plastic body melted a little. The spring tension of the fuze socket squeezed the fuze enough that after i shut the car down and it cooled and contracted it actually lost contact with the fuze terminals. The fuze still looked good to casual inspection when i started TSing the car, but upon closer inspection after pulling my hair out for an hour and a half i noticed that it had melted a little and was shorter than the rest.
I swapped in a new one, lo and behold, the car fired right up.

Double check your Relays & Fuses. The Charts on 928spec don't cover the the Euro S2 - the layout is different due to the LH. Look at the Wiring diagram. I would replace the critical relays.

I swapped the 4 important relays with ones that I tested as good with a workbench powersupply. Then I checked to make sure I could feel and hear them click when turning the car on and off. I'm assuming water got somewhere and I have a short.
The 928 Spec charts have a few errors, but cover most of the 84S2 stuff. I sent DR an email about the erros I found and I'm making an interactive chart on my Rennlist member site in my sig. It's partially done if you want to check it out.

Hard to believe 4 relays could go bad at the same time, but here it is.
