Possible fuel solenoid failure
Long read. Fyi
Went to the Dyno to get a retune after a dedicated fuel system install. First time activating the system this year. (System is only one season old).
Made a test hit on the Dyno and she leaned out bad. We traced the fuel pressure drop to the nitrous fuel solenoid.
Unhooked the dedicated fuel hose from the fuel solenoid and perfect pressure coming from the hose. Fuel comes out like crazy.
Hook it back up and take the fuel hose off the plate and activated the solenoid (it clicked). The fuel just dribbled out of the hose.
I unhooked the solenoid and put it directly to battery power and it clicked. I look through the fuel port and notice the plunger only moves maybe an 1/8 of an inch, leaving the port only partially open.
this didn't look correct to me, but can anyone tell me if the plunger opens the port fully? I just don't see how fuel can make it out of such a small opening.
I called the company and they told me to send it in. So I did.
I took a video of the plunger. If anyone is interested, shoot me a pm and I'll text the video to u. In the meantime I'll try and see if I can upload to YouTube.
Thanks for the help.
