Sorry Trucker forgot to mention that on that last run, previously mentioned, that when started to conk out in addition to switching to reserve I also tried with tank lid open but fault still apparent. Ialso stuck choke on which made it roar down the road but not smoothly!!!! Early indications that a run is not going to be successful , when cold starting, is that revs do not rise to approx 3000 revs on choke! ? I have to say that I am still in fuel starvation mode eg enough fuel in float bowls to take me down the road 1/4 mile occasionally sometimes fault is apparent immediately. Today purchased some fuel line cleaner etc will, after flushing exercise - raise tank as high as possible above bike and feed fuel directly into rail that joins carbs together and bleed out of each carb drain in turn - leave cleaner and some fuel to soak over night using pump etc to feed carbs. Perhaps given ? mark over pump drain all carbs and feed fuel/cleaner mix straight into rail.

I am inclined to agree that it is a fuel problem with the symptoms so far described, I cannot see it being the pump, I think you gonna have to bite the bullit, whip off the carbs and check the floats, everthing so far, tickover, choke, stuttering etc leads me to think she's only running on three. If that dont work, stick some triumph badges on it and flog it on.

Do not tempt me with Triumph badges, I had two Daytonas even if not running properly Triumph owners would think it was normal. My last Daytona spent 6mths of its time with me (7 mths) in the garage in bits eventually fixed it with plug tunnel seal but so pissed off with it returned to fold with my first SREX.
Just bought Haynes for bike today and found that pump might be working but could have faulty internal sensor. Fuel pump starts working when start button pressed providing Ignition on, "Engine Stop SW" not made, Clutch in etc. When fuel reaches certain pressure cuts pump off - could also mean have blockage and sensor could be working eg in rail for carbs??? If blockage might not detect fuel pressure drop so quickly etc??? Theories are great it is just proving them!!! Pump operation is controlled by relay which is suitably energised by inputs already mentioned. CDI also plays a governing role as some inputs are fed there first.
I once had a very much similiar problem with four wheeled monster which would drive for at least 10 miles then stop, it had two twin choke webbers this was cured by liberal spray of nasty stuff into carbs - blockage somewhere.

Forgot to mention that I have already tried that and also stuck choke on which had an immediate effect of launching me down the road up to about 3000 revs but you could feel that it was not smooth. Eventually managed to coax her home very slowly but noiced this time that she cut out at least three times but always restarted with a rough but maintainable tickover.
Bought Haynes bible yesterday and the potential for expense is enormous if not crud about.
Fuel pump relay needs several inputs to function: stop switch to run and two others from "Ignitor Unit" (CDI???) one of which also feeds ignition coil for pots 1 & 4, the other also feeds starter circuit relay. The bike always starts so both those last two inputs are present - no guarantee that they are both alway present especially very last one.
Fuel pump has internal sensor that monitors fuel pressure and if pressure reached will shutdown uel pump until pressure drops. If sensor faulty may shut down incorrectly or if blockage in rail that feeds fuel to carbs then may shutdown and stay shut down because pressure will stay artificially high for longer.
Theories oh theories. Going to check fuel tap for filter again as couldn't see one last time perhaps inside need to dismantle. Also going to make up cocktail of fuel line cleaner and fuel and leave to soak.

There isn't one for the ZRX. The closest match is No. 1681 which is the one for ZX900, 1000 &1100 liquid cooled fours '83~'87
It barely served me for my previous GPZ1100e.
Gimme 5 minutes and I'll dig out a link for an online PDF manual and PM it to you.

:jerry: ninjaron Hmmm . . . Just skimmed through this thread and was brought up short with the reference to a fuel pump Then re-read and saw that you're talking about a ZX6! Thot I was losing it for a moment there. ;D
