Not hard sit on fuel rail, remove small bolt little bracket that holds regulator, pops right out and install new one, one thing before removing it, remove fuel pump relay, and start engine till it dies, that way there will be no pressure in fuel rail.

I have a 99 ford svt lightning, it starts and idles but dies if you give it any throttle. I soaked a towel in gas to get it home


you should do a fuel pump pressure test it might be the problem, loss of fuel pressure will cause this to happen without notice

I have a 2003 Ford Expedition with a 5.4 engine, when I go to crank it, it turns over quite a few times before it finally starts, any ideas?


Check fuel system pressure if the pump has a bad check ball or the fuel pressure regulator is bad, pressure is hard to pressurize in the lines. Test dead head pressure then operating pressure the a fuel pressure leakdown test. That way you know what actually needs replaced so you don't guess. When you first pressurize the fuel system it should have 30 to 40 psi if it falls fast before you initialize starting the vehicle the check ball in the fuel pump is bad so the whole assembly and fuel filter will need replaced. If you start the vehicle and pressure does not regulate at 30 or 40 and you accelerate and the pressure does not max out it is a fuel pressure regulator. It might be in the fuel rail or in the fuel pump assembly in the tank.

I have a 97 Yukon that we just replaced the motor in, since then it will not start but yet it was getting spark and fuel. We checked the fuel pressure and it was at 10psi - we replaced the fuel pump,...


It may be a bad fuel pressure regulator, or did you test that when checking fuel pressure? A single pressure line from the pump inlet through the external fuel filter and into the fuel rail at the engine- if no blockage or restriction in the line, then the pressure regulator must be at fault. If the regulator is hard to get to, like under the intake manifold, you might want to open the line at some place after the fuel filter and check volume flow into a large container. Be careful, fuel under pressure can go everywhere, it's really dangerous and toxic. Use safety first and last.

Hard starting, no power, idles rough, check engine lite code shows misfire on #1,#2 and #3 cylinders


check fuel pressure, check fuel pressure regulator, change fuel filter. If fuel pressure is low it could be a bad pump, a clogged filter, or a malfunctioning fuel pressure regulator. If all those check out, then check crankshaft and camshaft position sensors.

I need to replace de fuel presurre sensor in a pontiac montana ,do i have to just replace the sensor ,o the sensor came with the fuel pump?thank you


Replacing the fuel pressure regulator, involves just replacing the regulator at the end of the fuel rail in the engine compartment, but fuel pressure sensor - does this mini-van have a fuel pressure sensor?
replacing the fuel pressure regulator: (1) locate it at the end of the fuel rail in the engine compartment,
(2) relieve fuel system pressure (3) disconnect fuel pressure regulator vacuum line. (4) remove fuel pressure regulator retaining screw (retain for re-use (5) using a shop towel to catch spilled fuel, lift & twist Fuel pressure regulator to remove it from the fuel rail. (6) remove/discard retainer and spacer bracket from the fuel rail. (7) remove fuel pressure regulator from the engine fuel return pipe. (8) remove/discard Fuel Pressure Regulator inlet O-ring (9) Check Fuel Pressure Regulator filter screen for contamination - if contaminated, replace Fuel Pressure Regulator. (10) Lubricate new Fuel Pressure Regulator inlet O-ring with clean engine oil & install onto the Fuel Pressure Regulator inlet. (11) Install the fuel return pipe onto the Fuel Pressure regulator (12) Install new retainer & spacer bracket into the slot on the fuel rail.
(13) Install Fuel Pressure Regulator onto Fuel Rail & tighten Engine Fuel Return Pipe nut to 13 ft-lbs (17 Nm). (14) connect Fuel Pressure Regulator vacuum line, (15) Install Fuel Pressure Regulator attachng screw & tighten to 76 in-lbs (8.5 Nm). (16) Inspect & verify that retainer & spacer bracket is engaged in the slots on the fuel rail. Grasp & pull on the Fuel Pressure Regulator.
to ensure that the Fuel Pressure Regulator is properly seated. (17) inspect for fuel leaks with this
procedure: On 2sec,(holy rollers), off 10sec will be left on, inspect for leaks while running.

Overreving with no power and excessive gas consumption air filter cleaned map sensor replaced fuel pump and filter


usually caused by busted diaphram in fuel pressure regulator allowing fuel to be drawn thru regulator directly to intake manifold. Pull vacuum line off regulator, plug line with golf tee, start car and watch to see if gas comes out of regulator. If yes, turn off car, replace regulator. The regulator sits near the fuel rail on the top of the engine as shown below. I will paste replacement instructions below from autozone.com in case you need to replace the regulator. Please let me know if you have any questions.

My 1995 volvo 850 turbo is hard to start when hot.


Check fuel pressure regulator.
Pull out vacuum line from regulator and see if there any gasolin inside . If there is , it's your problem. Broken diaphragm inside fuel pressure regulator.
Replace fuel pressure regulator.
If not , further diagnostics has to be performed by workshop.

1993 jeep wrangler 4.0. Jeep stalls when accelerator is slightly engaged. sometimes hard to start after this. sometimes starts right up. already replaced crank position sensor. What else could be wrong?...


The fuel pressure you listed is to low,
The regulator should keep the pressure down to at least 45psi,removing the vacuum from the regulator it should spike to at least 55-60.
Did it start and run better with the hose off?
replace the fuel filter first,then check the pressure again.

1998 Chevy tahoe Hard to start when cold


replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump
