Well my car still runs bad.

It worked fine for two trips. After changing the fuel pumps and strainers I assumed (yeah I know) all was good and did not check the fuel pressure.

Car started right up and no cold start issues. Went downtown and ran a few errands, sat in traffic, and had no problem passing on the expressway.

I let the car sit for a few hours and the symptoms came right back. Maybe they never went away.

New fuel pumps, strainers, and filters.

Here are 4 videos I made.

* Ignition on, no start.
* Ignition off after no start
* Start up
* Shut off

I am lost. Only thing I can think off is the fuel pressure regulator or maybe the ECM due to this thread with the same similar start up issues.

I see no leaks anywhere and all the lines are nice and tight.

Thanks for the help.
