Randomly no fuel pressure

[undefined0000]

Alright, so I really need to get back to Ohio (can't stay at school) and my car was warming up and warming up and boom, it died and wouldn't restart, I noticed that the fuel pressure was at like 10 when it's usually at like 30 after the car is off, and I can't get it to start. I installed a walbro today and it worked fine all day. I did notice that it is really quiet, not as loud as people are saying. Could I have forgptten something or could it be a bad pump?

Will the car turn over?? Is the pump new or used? I would also check all fuel lines, connections, and fuel filter and just start working from there. And by boom, it back fired or what..?

I see PFR in your mods ..was it installed??

Did you put the o-ring that goes on the top of the fuel pump back in correctly?

Got it fixed, literally took the fuel pump out, looked at it and put it back in and it worked

Check your connections and figure it out unless you want this to potentially happen at the worst possible time.

Best fix ever.

You likely had a weak connection with the plug so the pump was cycling on and off.

I'd bet it was the fuel pump o-ring that wasn't seated properly (as mentioned above). If he was seeing low psi, I doubt it was a connection issue and was just bleeding off quicker than normal.

Wouldn't that cause issues immediately instead of cause issues hours down the road?

 

[snowborder714]

I think it could go either way. Might not have been seated properly and you hit a bump and shift it off the o-ring...maybe?

True, but it would still be a good idea to poke around a bit. What if a teenager in a riced out civic pulled up to him at a light and then his car shut off right at launch? That would not be allowable.

Street racing isn't allowed anyway, so why would he be launching at a car next to him at a light?

If he's "launching" on public streets in an effort to upstage a teenager in a riced-out civic, then he deserves to have a fuel pump quit. It's much more effective (and safer) to just look at them and laugh, and then drive away normally.

hahaha true enough. 2STEP THAT MOFO

Thanks for the replies guys! This happened to me as I had to make the 7 hour drive back to Ohio from Pennsylvania. It made it the whole time and is still working after being here for 2 days or so. I did tighten the ground a little bit when I pulled out the pump, but it already seemed tight. I'm guessing that was it. I'm still weirded out by how quiet the pump is, its a new genuine walbro 255. Do they eventually get loud?

btw, all of my car buddies down here are honda people. They make fun of me for having an "un-reliable" car, but still respect the power, even with my crippled state. I think honda people are scared of DSMs, its those subbies you gotta watch out for.

As stated, it could have been the presence of either the O-ring not being seated properly or a bad connection and it was jarred while driving - shifting parts and things seating/unseating after installation are occurrences that tend to happen. Regardless, make sure to watch it and be prepared for a few days that it could happen again. Keeping this sense of mind will ensure that you're at least somewhat prepared.

As for the loudness of the pump, it can vary. My first pump was quiet as well while my second could be heard outside of the car. The question is - did you perform the rewire for the fuel pump? If this has already been answered and I've missed it, I apologize, but if it has not been rewired than that would likely be your answer as to why it's so quiet.
