rapid flickering of dash lights/relays
I'm new here and hoping for some help as I am stumped. The victim is a 95 lesabre, 85k miles in excellent shape, well taken care of and always garaged. The issue with this car is that I get a rapid flashing of the warning lights on the dash (all of them including battery, temp, SES light) along with the rapid clicking of the fuel pump relay. Thinking it must be an ground issue I went in search of any grounds I could find in this car. Cleaned everything including battery terminals but all (that I found) were perfect. It is random and of course when this happens the car stalls and/or won't start. I pulled the PCM out from under the dash and wiggled wires but nothing helped. All connections appear solid. I have done a lot of search on this and found a few topics of people with similar problems but no resolution in any of the cases. Has anyone seen this before and can shine some light my way? Is the PCM (the larger of the two in the car residing inside under the dash) a known issue on these cars? Many thanks in advance.
