Did that today. Getting 13.6 volts with good ground and no drop.
Driving me crazy to the point I'm guess I'll just find another inline
pump motor to install.

Did you check the tank for crud on the bottom? Might be
plugging the suction line when pump runs.

Yeah, I checked that too. I have pretty good flow, the fluid will
squirt about 8" out of the line but not good pressure through the
line. Thought a new pump would fix it, but it's exactly the same.
I'm stumped.

Replace what you haven't replaced yet.

The same techniques for finding a electrical problem apply to this type of
fluid flow problem. You know you have good pressure at the pump. Move on
down line. Beyond the pump there is a coulple dollars worth of line, maybe a
couple fittings and then the spray nozzles. Hook the line back to the pump
and move to the next connection. Check for pressure(voltage if you are
checking electrical) Process of elimination. But for the money you would
probably be better off just to replace the lines all the way to the spray
nozzles. Use only windshield washer fluid. In the summer some people try to
use soap and water which do not protect against corrosion in the system. A
little piece of rust in the line can cause havoc. Do not use glass cleaner
ever. Amonia will degrade the rubber lines. A flake of rubber will plug you
up.

replace the nozzels, I've had this happen, the nozzels brake oor hard water
build up happens an dthat will probably fix it!
