Do relay boards have intermittent problems? I’m having problems with the fuel pump. I lose power to the pump. Switch relays on the side of the road no go. Get home check power at the fuse ok, take a headlight relay, powers right up. Could I have a bad board connection? Intermittent? Thanks. Dave

Dave They can fail in multiple places that will impact the fuel pump and I have seen them with intermittent failure issues. Last one I fixed was one of the hardest ones I have had to track down and was very intermittent. Issue on that one was at the 4 pin connector to the injection system, weak connection at solder joint for the fuel pump relay trigger wire. It would test out fine when the connector was not on it but with the 4 pin connector installed it stressed the joint enough to intermittently loose connection. I have had other that failed at the relay socket itself. Old relay boards with no availability for new replacements is probably the biggest headache I have with keeping d-jet going these days. (this surpassed old worn out distributors when the 123dizzy became available) |
