240 Abrupt Shutdown in Traffic Solved 200 1991

A long while back I posted about my son's 240 that would shut down INSTANTLY from time to time. It was aggrivated by running a/c or seat heaters or any electrical load. That would make it shut down sooner and more frequently. The P.O. replaced fuel pump already. The white FP relay under dash WAS fiddled with because it was greasy and hanging from the harness instead of clamped back in place. We took that relay out anyway and found almost invisible cracks in the expected places.. resoldered and bingo, problem has not come back ever since. Several weeks of driving and AOK. (you almost don't want to trust it, but it's really been fine).

The additional load on the electric system effect really made me go off on a bug hunt. It may have reduced the the overall working voltage to the relay harness by a bit, making the pump trip out sooner and more often. That's my only explanation of why the extra load made more aggrivated symptoms. It had nothing to do with that big terminal block behind the battery. There is NO 25 amp fuse there that I was looking for as culprit, just a terminal block junction.

Hope this helps somebody. Even if that relay has been obviously checked by somebody, do it again for yourself.
