Hello out there....my car has been dying after getting a good warm up but starts the next morning. The tell tale symptom is that the fuel pump does not run when the stall occurs and even after hours of cooling off it still does not start...but it does in the morning....???
So talk on the street is the relay board is too old to work properly.....the description of 914 LTD's improved and rebuilt relay boards matches the symptoms of my car perfectly so as soon as I scrap up the money I will buy one.....meanwhile I have two spare relay boards and one looks really good. Is there a way to bench test the relay board before I swap the boards ?? These cars sure keep you on your toes and a relay board with fresh soldered connections sure sounds appealing so Brad is holding one for me. So back to the swap out....I hate to go to the effort just to install another faulty board. Look forward and appreciate any and all comments and help....thank you very much!!!! gg |

It’s important to collect hard data on these issues. Otherwise you may think you’ve solved the problem, only to have it crop up again. For example…you replace the relay board and everything works fine. Then, a month later it starts happening again. You finally start to methodically test and realize there was a loose connection in the harness plug and the act of replacing it on a new board improved the contact enough to think the board was the issue. BTDT. Like Ringo….I say this with peace and love, but if you want to solve problems with the least amount of frustration, expense, and rides on a flatbed, implement a testing procedure that definitively identifies the problem. If, at the end of the process you can’t say with specificity exactly what the issue was, you’re only guessing that the problem was solved. If it were me… -Use known good relays. All of them. Don’t always assume that new=good. -Confirm that there’s power at the pump leads -Have a friend repeatedly turn the key to the ACC position while you grip the relay board in various positions. If you hear the pump cycle while pressing relays or the bottom of the board, you’ve found the issue. (This is actually what happened on my BB). Bottom line…gremlins are crafty. Being able able to re-create the problem at will…or identify the break in continuity on a DMM is the only way you can be sure you’ve slayed this beast! |
