My biggest challenge was pulling the distributor gear. The varnish accumulated made it difficult to pull - I ended up breaking the gear, so ended up buying a new distributor anyway, which came with the pickup already installed.
Would be cautious over blindly replacing this pickup sensor part - if you can't pull codes, there may be something wrong with the computer itself. Suggest this needs to be figured out first.
Good luck - and keep us posted.
