I recently purchased a 914 that had been sitting for quite some time. I am new to the forum and new to the 914 as well. I’m questioning whether I’m getting electricity to the fuel pump I’ve tested the various things I’ve read here and think it might be in the relay board. I have the relay board removed looking at the backside I noticed there’s some of the tarp pieces missing. Can these boards be repaired? They appear to be expensive to buy. Any help or suggestions greatly appreciated. Mike

Hey Mike -- They can be repaired in most cases. You need to remove the black sealant off the back. Soak it in a strong solvent and gently scrape that off. That takes a while. Then inspect the traces visually and check for continuity with a multimeter. If there are any issues or doubts, fix those areas with some careful soldering. When done, you can seal it back up again with something like Liquid Tape (available at Home Depot / Lowes).
Have you gone through the fuel pump troubleshooting guide? There are a fair number of things that can go wrong and keep the pump from operating. (IMG:style_emoticons/default/welcome.png) |
