What did you do with/to your Boxster today?

This week, siphoned out the 5 gallons of old gas. Put in 2 1/2 gallons of new premium. Still won't start. I replaced the fuel filter, it back flowed black gas. No gas flow from the feed line for the filter. Fuel pump isn't working. I jumped the relay connections, the fuel pump isn't working (it did work before all this.) I drained the gas, wiped out the tank of the last qt. of gas. I got some tank cleaner, water based. Mixed with about two gallons of tap water and dumped it in. I sloshed it around with a rag on a stick, fuel pump and sender out and on a table. It sat over night. Siphoned it out into a bucket. I used my shop vac to remove the residual water and then wiped it down with an old towel.

Yesterday, after letting it sit opened up for a couple of days, I installed the new fuel pump & the old sender tower. I put in a couple of gallons (the same ones used earlier) of premium, I'm planning on going out and getting 10 more so that the pump is submerged completely in gas. Then I'll jump the relay and see what's coming out at the input for the filter. That's where I am on the fuel system process. If it starts, it will be getting Techron for the foreseeable future.

I have a set of O2 sensors NIB to put in as well.

I have checked the fuse, btw. With an multimeter. It's the C4 fuse, btw.

Hmmmmmmmm?

I got the 10 gal of premium in yesterday. Pretty much all I could do, I've been cleaning and cleaning around the house as life interferes with Boxster project. I'll probably have time today to try to start it.

Other social isolation projects include a new set of struts for the Boxster. Got the struts, need some of the other parts.:dance:

Ordered a new gas cap because the tether on mine gave up the ghost. I had credit card points so it cost me nothing.
