A&Q about 350Z
Q:
Quaddriver: Thats amazing, 214,000 miles and 14 years of continously running out of gas. According to the handfull of myth believers I know, you should have went through alot of fuel pumps, countless filters and injectors, and a few engines. Have you had ANY mechanical problems that might have even been remotely related to doing this?
A:
I ran my 89 Cavalier out of gas several times before I figured out the gague was/is incorrect. That was 15 years ago, I still have the factory fuel pump at 300,000 miles. Doesn't seem any harm was done.
A:
Turbo and sc theory sounds very realistic. Anybody else back that up?
But to restart on a previously empty tank: Electronic non mechanical injection (mechanical pump is rare in injected gasoline applications) Turn ignition switch off and on two or three times (cycling the priming function of the pump) then start. Old school carbureted with mechanical pump: Pour equivalent to three teaspoonfulls of gas into carb. choke stack, start and allow to idle for a minute or two. Repeat if needed. If electric fuel pump: start as normal. This info came from a few owners manuals I've seen. I still havent been properly instructed on how to restart a rare but existant fully mechanical gasoline injection system.
I hear they realy are a pain. Does anybody have any experience or knowledge of them?
A:
300,000 miles. Pure G.M. quality? 2.2L?
A:
well aside from maint stuff, at 175K the pinion bearing went out on the rear axle so I rebuilt that, and fairly recently at 211K I lost the OD spring/roller clutch so I rebuilt the tranny. not sure I can blame either on the fuel pumps tho.
A:
Pump still running, full 50 psi, just slightly warm.
A:
hum this thread might turn into.... Fact or Friction
at some point.
A:
That 1989 is a 2.0 with 88 horsepower. Hold on to your seats folks.
A:
My test pump was still running and sounding just fine and still produced 50 psi when I disconnected it at noon today. No burnt smell or excessive heat. I believe it might be safe to say that "burns up the pump" is eliminated. What about further down the line?
A:
Come on. Anybody? Ok how about that old sugar in the gas tank myth? (sugar dont mix with gas, chemically impossible, stays granular in tank and is caught by the filter clogging it) Myth believers say it "blows up" the engine.
A:
I have head that myth is that true??
A:
Which one? The sugar? No. It only clogs the fuel filter and possibly the "pre-pump sock".
The out of gas? Personally still undecided. But leaning toward no.
Have you heard anything that you think might be a myth?
A:
if your fuel pump is in the gas tank without gas You WILL burn your fuel pump
A:
Again this is a depends situation...
If you were running a top fuel dragster and the fuel rail stopped releasing fuel under full acceleration, you would end up with a very large bill for parts and a lot of labour picking up the parts around the strip.
An old 500cc two-stroke MotoGP bike at full speed along the front straight at Monza would lunch itself too. It would be leaned out and no lubrication...
In an average domestic car cruising along the road - probably would not have any significant effect. Not enough revs, heat or load.
A:
READ the ENTIRE thread.
Quit just repeating yourself. And if you believe this is realy true, how do you realy know?????!!!!!
