Last couple of days when I step on it the truck didnt feel like it was pumping water/meth ( power wise ). So I had some time today a had a look under the hood. Everything looked fine so I took the 2 lines off the intake, and took the boost line off and applyed 25 psi ( air compressor )to the boost line and watch the injections lines. I could hear and see the pump running then stopping, then running then stopping. With a steady 25 psi applyed to the boost line the pump should run steady.( the display was reading 100% injection rate the whole time ) And the volume of water/meth coming out of the line was very very low. This is with open lines, no injectors on the ends. I could stop the flow with my thumb for 10 sec. or so then it would spray out under pressure. I'll try to make this short. I unhooked the line on suction side of pump ( between tank and pump ) and fluid ran out via gravity full volume. Checked all lines, wires, etc. I had it so simple it was just tank pump 20' of line and open to atmosphere ( no check valves, Solenoids, etc. ) And it would still just barely run out the other end with pump running intermittently at a steady 25psi on boost line reading 100% injection rate on display. The only thing I could come up with was maybe the monitor itself is NFG and sending erratic signals the the pump.. I did not bypass the monitor and try running the pump straight off 12 volt. But I will when I get time again. I know a few people on here that have had problems with the controllers. - My contoller was on my dash ( where it is suposed to be ) warm/hot in near full sun when I was doing all of this.
