I just installed an in line fuel gauge, reading 60PSI survey say to much, car run fine always! after pinching the return hose for a second pressure went to ZERO never came back, now good car wont start , fuel pump hum like normal 5 seconds after key ON but pressure zero kaput feel very stupid maybe tomorrow feel better .. maybe not
any ideas how to revive this zxt will be very welcome

 

Did you pinch the return hose before or after the guage? If you squeezed it after the guage then it shouldn't have dropped, it should've shot up. If you squeezed it before the guage then that was normal. As far as your car not wanting to start after doing so: Are you sure you're not outta gas? It's always the little things

 

pinch after FPR on returning line, the gauge is right after the fuel filter, on the way in, car has NO pressure at all after incident, there is a reset something somewhere or what can be fried?

 

Maybe something got clogged at the filter??? thats a wierd prob..

 

filter is recent, car/pressure die at the same moment return line was pinch, something went south but what? I could sell my soul n buy a new bosch if I knew for sure

 

Sounds like a hose popped off somewhere. Sounds simple enough, but check it out. Maybe you popped a hose off the pump. That would explain the normal hum, but zero pressure. Sometimes the hoses are just clamped tight enough to hold, but when an added force [see also: pinch] comes along, it's enough to go POP ... and off it goes.

 

Im in a mission from God right now,will post results, appears to be the fpr not holding, so pressure just go around but for now just a theory, pinched the return line one more time with key ON n presurized to 60 n hold (residual pressure) so no leaks..got to go.

 

Sorry, I couldn't help myself.

 

You forgot: N you traded the ______ for this?*

* 1974 Monaco 400 police package; owned one back in 85-86 never had so much fun in an 325 dollar car, n the for sale sign with no price on it said: by appointment only GUAU! must be asking for a lot of money..crazy ol man ask for 400 n the rest is history an a set of cheap tires on the back every other week LOL what a punch! you could scream the tires for as long as you want!

 

OK car is back n flying like is was meant to be: from 60 psi to 0 then back to 30 plus residual pressure, in hours for me, minutes for the wise. The solution: new German AFPR. What do we, the untrained, learn from this? fuel pressure gauge rules!
is like having an eye looking 24/7 into the FI
