I have a 1974 FI 1.7, my problem is the relay continues to foul with corrosion. I clean it with electrical contact cleaner, but the problem which clears the corrosion problem for a short time. The car runs flawless except this problem and I really can't rely on the car any longer. I there a way to bypass the relay directly to the fuel pump? Thanks Mike

Mike...how about reaching out to this community on the WTB portion of this site and get yourself a relay board in good condition. Might be a bit safer than hot wiring your pump.... (mike and I have been chasing relay boards "unsuccessfully" on ebay for a while. Can't seem to reach seller's reserve) |

Thanks Mike Have you used dielectric grease after cleaning? It should prevent any corrosion from occuring. |

And instead of cleaner in a can .... try a wire brush too!

There is more resistance somewhere...
try pulling that big plug near the firewall and cleaning those contacts. And the cleaner in a can isn't close to a good physical wire brushing for accomplishing a better connection. Is the fuel pump fused seperately in an unmolested car? If so, I would check/ clean that area as well. |

It's a real nice car with only 56K and this is the only problem I have had. Thanks again Mike |
