So Blanche ('73 White 914-4 1.7L) was running great last summer until she simply stopped on I-95 in Burlington, MA. Simply no spark anymore. Having no time to deal with it, she sat until today. I figured out the spark problem, but now the fuel pump, won't. Familiar with this type of issue, I open the relay board and check the fuse and the relay. I've got 12V where I'm suppose to - both sides of fuse, pin85 of FP relay when key on (FI Brain energizes to close circuit to join pin30 and pin87 I believe). PIN13 of connector closest to firewall, which diagram says goes out to FP itself, shows continuity to ground, so I'm guessing broken wire somewhere. Sounds reasonable/plausible? Fuel Pump was functional before I put her away.

Pumps do gum up or fail.
Run hot wire to + terminal and another to ground and see if the pump will run at all as a test. If it does, go from there with the tracing of wires. |

Hot wired a spare battery to the pump and it DIDN'T run. Very quick trouble shooting. (I guess the old geezer DOES know what he's talking about). (IMG:style_emoticons/default/lol-2.gif) |
