why does it take a few turns of the key to get fuel all through the system to start h
So as said, I have to turn the ignition to the last part before starting it a couple of times to get fuel through the system before actually starting it up. otherwise its a painful long hard start.
what is lacking here?
I have 682cc inj, tuned by a Neo, wideband. and to my knowledge everything else as far as fuel is stock.
is this usually a pump, rail or some other kind of problem? thanks for reading.
haha. yeah, I just wanted to ask knowledgable people so I don't buy unneeded parts cause there's so many others I want. alright, I'm on the hunt for a walboro...thanks
btw, i have a walbro i'll sell you for 50 plus shipping. has about 3k miles on it. just took it out to go back to stock a little while back and never put it back on because i only have stg 1 injectors now and it's kinda pointless but as far as your issue, probably a pump. but to narrow it down, try priming your system by just turning the key to the ON position and listen and look for the red light to go out. if you hear a whine and then it stops once the light goes out you're ok. if not, probably a regulator issue. PM me about the walbro if you need it man.

exactly. I have to cycle it to hear the whine sound twice. then its primed for a good start. so ill pm you on that walboro black and blue prob next week. sounds like my stock is kicking the bucket.
could the fuel pressure regulater have any play either.

yes, worn/missing o-rings will bleed down your pressure, common problem

alright good deal. have it packed up and ready to go for ya. it'll probably be cheaper to just go pump first, if you still have the issue, then go regulator(i don't see as many regulators on here as pumps) and then injector seals etc....let me know when you are ready for me to ship it out to ya.

How about putting a $20 fuel pressure gauge on it to know 100% beyond a shadow of a doubt what the pump and fp are doing before wasting $$ on parts that aren't needed.
With a cheap fp gauge you can TEST pump up time, bleed down rate, whatever in about 10min. And the next time you think you're having fuel system issues you can just TEST the f'en thing instead of taking a bs opinion poll.

yeah, your right. but I dont know what to test for. what pressure tells me what is failing. im asking for a reason cause im still learning..
If the fuel pressure is falling at WOT and A/F is climbing(getting leaner), it tells you that there's less fuel supply at the rail than the jectors are trying to spray. There's either a restriction in the fuel line, and clogged filter or the pump is bad.
Low but stable fp tells you the regualtor is probably not working.
