This sounds like the fuel pump is shot. The pump has a 'dead' spot and when the engine is started by using 'nasty' starting fluid it will go to the running mode and run fine. Never use starting fluid!!! A bit of gas is best, just use common sence. Frankster016

SOURCE: fuel pressure regulator had no vacuum line connected

another engineers wet dream. think of it this way . what is normally in the intake when the engine is running.. answer vacume, hence the regulator gets its vacume without a hose connected to it as its already in a full time vacume chamber.no hose required . ps be carefull to seat the regulator and o rings securely into the housing befor you reattach the secureing metal clip.
good luck chris

SOURCE: fuel pressure regulator

Two places to look...if you have separate injectors for each cylinder then regulator should be at the front end of the fuel rail. If you have throttle body injection it is on the throttle body itself.

1999 chevy tracker, no power, can't get over 50 mph. Changed fuel filter but no cahnge


I assume you have already checked your air filter and air inlet for clogging. Another simple diagnostic is to sniff the exhaust when the engine is cold. If it smells very dirty or like unburned gasoline, you either have too rich a mixture or ignition problems.

If that is not the issue, verify that your fuel system has adequate pressure, and that it holds pressure when the engine is accelerated. Most fuel injection systems have a Schrader valve somewhere under the hood for this purpose, and for safely releasing fuel pressure for service. You'll need to get a pressure gauge designed for this purpose - many auto parts stores have some sort of tool deposit/loan program so you don't have to buy it outright. Inadequate fuel pressure can be due to a faulty pressure regulator, failing fuel pump, dented or kinked fuel line, or clogged fuel pump inlet screen.
Another possible cause for poor high-speed performance is a slipping torque converter. However, there will be a noticeable difference between engine acceleration and vehicle acceleration in this case (engine RPM will jump, but the car will crawl).

Is there a return hose that plugs into the fuel pressure regulator of my 99 chevy tahoe 350 5.7 vortec?


The regulator located inside the plastic intake plenum? There is no hose. They just work off the vacuum present inside there.

Where do i find fuel pressure regulator on an 2001 tracker v6 the engine is starving for fuel when going down the hwy allready replaced fuel filter


it's on the end of the fuel rail. Vacuum operated regulator failure usually results in rich condition. You should check pressure to see if your pump is getting the job done. Cannot find the spec on pressure but a new pump for your car delivers 80-100 psi. Let me know if you have more questions.
