No but when I read this I got suspicious!
" Car: 94 MTX; brand new factory crate engine, original: injectors, fuel
pump,O2's (100k)".
The factory pumps are not that great when new and now yours is 12 years and
100K miles old. After 100K miles on a fuel pump I consider replacing it as
just normal maintenance.
