Pump works, but getting no power.

Solved one of my problems. The inertia switch must have received bad voltage from the relay and melted the plastic around the contacts.

At least now I know what the inside of the inertia switch looks like.IMG_3746.jpgIMG_3747.jpg

That's not a sign of bad input Voltage. That's a sign of resistance from poor contact of the switch contacts. Once it starts it gets worse until you have a melt down.

If you have an "early" inertia switch, there was a recall because they go bad. The newer one has a splotch of white paint on it and it was moved to the side kick panel, not on the Lambda counter.

Correct David the 81 issue inertia switch was recalled for exactly this reason so once this switch is replaced with the revised '82 on switch the problem will not recur. The recall specifies relocating the switch from the lambda counter bracket to the bulkhead panel behind the hood release bracket to avoid incidental activation and more easily identify the switch is updated. All 81's are part of this recall and there are two versions of improved factory replacement parts to add to the confusion. The recall switch #109277 had the white splash of paint. The later switch #111209 used in 82 & 83 cars had a small S stamped above the production number on the switch housing. Both improved switchs were issued as replacement parts but both used a dark steel center terminal in place of the early defective units all brass electrical terminals. All 81 owners who have the switch mounted on the lambda bracket should inspect to see if its updated and then relocate if it passes muster. This is rather important for all '81 owners as the failure rate for these switches is approaching 100%.
