I checked fuel pressure and it was great, even after sitting for 30 min it still held.

The car would start and run for about 3 seconds, and then not fire again until some hours later.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I just picked up a 99 Boxster and am trying to bring it back from the dead. It was last running in the fall. The car would start and run for about 3 seconds, and then not fire again until some hours later. I took a chance and replaced the Crank sensor (no tach movement when cranking). Then the car started for like 20 seconds with me feathering the gas and backfired and died. I looked under the car and there was a puddle of fuel under the passenger side from an exhaust junction. I checked fuel pressure and it was great, even after sitting for 30 min it still held. I took the throttle body T section off from between the intakes and there was fuel in both intakes and the T. My guess is some sort of vacuum issue that’s pulling fuel into the intakes? Any ideas? Thanks in advance!

POST 2Original post

Fuel pressure regulator has a ruptured diaphragm?

POST 3 / ORIGINAL POSTEROriginal post

Would that suck Fuel into the intake?

POST 4Original post

I guess not, my error. In the moment I was thinking that the regulator had a vacuum line like many Porsches, but these cars do not.

Evostumpy, you've got two identical posts going on. Were I you, I'd kill one of these threads and focus on just the one. Sent from my SM-G970U using Tapatalk
