jwa fuel pressure sensor
 

Got a jwa and I can't get the fuel pressure sensor to work for some reason. I'm running it at the vp using a fitting that will allow it to work with my airdog. There's the original airdog fitting and then the swivel fitting with a port built in and the fuel line connected to that fitting. I get the default when its unplugged of 34 and when I plug it in I get a reading of zero. Why won't it pick up the fuel pressure? This is the second sensor I've tried because I thought maybe the first one was faulty and edge kindly sent me a new one but still the same result. Anyone had this problem? Any help would be appreciated. Thanks guys

Can u post a pic of the fitting your using?

Well I don't have my computer its in the shop so I'm using my phone. I got it from summit and its red and blue anodized. About the only thing I can do is give a website because I don't think I can post a pic from my phone.? So ill get the site and if you want to look cool but I will have to wait until I get my comp back to post a pic.

Hell I can't figure out the page on my phone but its a russel performance fuel pressure takeoff -6 an male to -6 an female with a 1/8 in test port if that helps at all.

does the test port have a shreader valve in it? is the regulator opening it if it does?

Is it one of these?:

Just something to try, a shot in the dark, try grounding the fuel pressure sensor. In theory it shouldn't need a ground, but maybe that aluminum fitting isn't allowing a ground to happen and not allowing a reading.

That's exactly it. I didn't even think about it being aluminum and maybe not being compatible but since the unit is grounded I don't think I would have. But I guess it is definately worth a shot. Would I just splice into the sensors wire and run a ground from there? How would you do it? And what is everybody else using because I know I'm not the only one with a jwa and an airdog running its fps?

I'm running a FASS, but I have it run into the filter base. I have a Banjo bolt with a 1/8" NPT port in it for my pressure gauge.
Just try taking a wire from a known good ground, frame, block, or battery, and touch it to the frame of the sensor, where the wrench would go to install/remove.
It's a long shot, but it may work.

That's an idea. Ill give that a shot bud. Thanks for the feedback. Keep ya updated

Well gave that a shot. It was strange. I got nothing at first and then I moved the wire around and got a reading of 31 but I hit the throttle and no change from 31 but I also jiggled the wires to the connector that go to the fps and that's when it changed I think. But it went right back to the default. Arrrr this is becoming quite frustrating. This was a big reason I wanted the attitude monitor. I don't get why it won't pick up the pressure. Unless its in the module itself and the edge tech guy was no help what so ever this afternoon. He suggested putting a fitting inline like a t filling. That's all and well but that just doesn't seem like the best way to run one. Ahhhhhhhhhhhh

I searched for a fitting for a while and this is the one I found. There's gotta be another one out there that is brass

There is a possibility that the wires and pins weren't crimped properly at the FPS harness plug. Only way to tell is disassemble the connector.
I assume you have the JIC fitting on the VP, and not the factory Banjo?

The fitting coming from the vp is the flare fitting supplied by airdog and then the anodized fitting yes.
