Also going to change the oil this week and send it in to Blackstone Labs for analysis.
Car is still not 100%, I think near the end of summer I'll do a major overhaul of maintenance items.
Thanks everyone for their input and advice!!
Here's a video of a cold start up after the fuel pump install - night and day difference: |
Makes me wonder, since you say your HPFP was replaced 3 years ago by the previous owner, how reliable actually are the rebuilt HPFP they're selling today? Did you buy your HPFP from FCP?
