I was driving and came to an incline and halfway up it lost power and never regained it. Then it started sounding like a hissing sound almost like a hose was off but can't find one missing and when I made it to a friends driveway close by soon as I turned in it quit running on me. The car will crank back but when you give it gas it spits and sputters and cuts off.
Do you
have the same problem?

Hi and thanks for using 2CarPros.

Many things can cause this. However, based on your description, the first thing I would check is fuel pump pressure. If it is weak, this can be the result.

Here is a link that shows in general how this is done:

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

Here are the directions specific to your vehicle. The attached pictures correlate with these directions and the manufacturer's specs are included.

FUEL PRESSURE TEST
Pressure Gauge Connection

Picture 1

- Check that the battery voltages is above 12 volts.
- Disconnect the cable from the negative (-) terminal of the battery.

CAUTION: With Airbag, work must be started after approx. 30 seconds or longer from the time the ignition switch is turned to the LOCK position and the negative (-) terminal cable is disconnected from the battery.

- Put a suitable container or shop towel under the fuel filter.
- Remove the union bolt and two gaskets, and disconnect the fuel in let hose from the fuel filter outlet.

- Install the fuel inlet hose and pressure gauge to the fuel filter outlet with three new gaskets and the union bolt.

Torque: 29 N.m (300 kgf.cm, 22 ft.lbs)

- Wipe off any splattered gasoline.
- Reconnect the battery negative (-) cable.

Installing Jumper Wire

Picture 2

- Using a jumper wire, connect terminals +B and FP of the check connector.
- Turn the ignition switch ON.

Reading Pressure Gauge

Picture 3

- Measure the fuel pressure.

Fuel pressure:
265-304 kPa (2.7-3.1 kgf/cm2, 38-44 psi)

- If pressure is high, replace the fuel pressure regulator.
- If pressure is low, check the following parts:

Fuel hoses and connections
Fuel pump
Fuel filter
Fuel pressure regulator

- Start the engine.

Checking Fuel Pressure - No Vacuum To Regulator

Picture 4

- Disconnect the vacuum sensing hose from the air intake chamber and plug the air intake chamber outlet.
- Measure the fuel pressure at idling.

Fuel pressure:
265-304 kPa (2.7-3.1 kgf/cm2, 38-44 psi)

Checking Fuel Pressure - Vacuum To Regulator

Picture 5

- Reconnect the vacuum sensing hose to the air intake chamber.
- Measure the fuel pressure at idling.

Fuel pressure:
206-255 kPa (2.1-2.6 kgf/cm2, 31-37 psi)

- If pressure is not as specified, check the vacuum sensing hose and fuel pressure regulator.
- Stop the engine.
- Check that the fuel pressure remains 147 kPa (1.5 kgf/cm2, 21 psi) or more for 5 minutes after the engine is turned off.
- If pressure is not as specified, check the fuel pump, pressure regulator and/or injector.
- After checking fuel pressure, disconnect the battery negative (-) cable and carefully remove pressure gauge to prevent gasoline from splashing.
- Connect the fuel inlet hose with two new gaskets and the union bolt.

Torque: 29 N.m (300 kgf.cm, 22 ft.lbs)
