Hey guys,
Since converting my rig to EFI (3 years ago), I have noticed that when the rig sits for a week or more, the fuel lines seem to completely drain, and then they take forever to pressurize. This has been the same both when I ran external pumps and now with my in-tank pump.
Is there such a thing as a check valve to hold fuel pressure in the lines? I tend to think there must be. My other fuel injected vehicles can sit for months, and they fire at the first bump of the key. My Bronco... a week of not driving it and I've either got to cycle the pump with the key (repeatedly), or ground the test lead on the scanner connector and run the pump for a minute or so.
I don't think I've ever had another fuel injected vehicle that acts like this, and there must be a one-way check valve I can put inline somewhere... or I just deal with this minor annoyance. Once the fuel system primes again, the engine fires right up and runs like a champ.
