My 1995 LeSabre (3800 v6, 62K miles) has a stalling problem, no engine power, but still has electric. It happens randomly and intermittenly. Most times it will restart but has been increasingly difficult to restart. The only indicator prior to stalling is the speedometer “surges” and then the loss of power. Dash lights come on (oil, voltage, CEL). Sometimes the CEL will flash in time with a fast clicking that I believe comes from the fuel pump relay under the right side of the dash. Until this clicking stops the engine will not restart. I have replaced ignition control module, and then the crank and cam sensors. Replaced PCM with rebuilt and it was worse (defective?) and put the old one back in. Mechanic can’t find any codes to determine what is causing it to stall, except possibly PCM is bad. I’ve got my own ideas for the next fix but wanted to hear from the community.
Thanks in advance!
