No, what I am suggesting is that the replacement of the PSE DID repair your car since the PSE on a 95 controls the action of the striker tongue. Please reread my previous post. The CA pump only controlled the striker tongue up until VIN 118121. Your friends 92 is probably pre-118121 and may very well have needed a CA pump to repair his car.
I am unaware of the cost difference between the CA and the PSE.
Yes there is a modified striker tongue for the post-118121 cars, it is the only one available for these cars. It is faster acting, they had complaints I guess on how slowly the lid closed.
