SOURCE: car dies when accelerate. do i need new fuel pump?

Hello;
It sounds from your description that the fuel pump is weak. To check the fuel pressure you need a fuel pressure test gauge for fuel injection. Attach the gauge to the test port schrader valve and turn the ignition to the on position. Record the reading. Now start the engine and record that reading. Unplug the pressure regulator vacuum line and record the reading.
The pump should have pressure with in specs but if low, start with the installation of a new complete pump. It is located in the fuel tank. Also replace your fuel filter.
Hope this helps you.
Thanks;

SOURCE: ford fiesta power loss

You need to check for codes to begin with. If no codes then we can start guessing. A code is pretty strait forward. Without a code, hands on will be the only way to diagnose this issue.

86 el camino stalls under load


As mentioned above, engine could be starving for fuel; but
also consider ignition system - as engine makes more power, maximum cylinder pressures increase. A higher spark voltage is then needed to ignite mixture (at a few degrees before top dead center... top of piston travel).
If coil is weak, plugs fouled, or plug gap too wide, adequate spark may not occur. This may cause missing,
loss of power, sometimes backfiring (backfiring may occur if timing is off, or intake valve leaky, also). If you replace the fuel filter, 'kit' the carb, but problem remains,
look to ignition system.

Diagnostic process - put a fuel pressure gauge in line, where fuel line enters carb. Rig so can see gauge, while driving. Have a passenger watch fuel pressure as you drive; especially while accelerating. If fuel pressure drops during acceleration, then its either fuel pump or filter. If pressure remains stable, consider carb issue.
If possible, test with exhaust gas analyzer, while engine
under load (possibly at an emissions test place). If lean under acceleration, its a carb problem. If not, look at
ignition system (emission test diagnostics should help here, also). Oh, and one thing I did once.... forgot to release parking brake..... duh.

Best of luck !

My KIA RIO 2003 idle OK, but when I accelerate it has no power, I get a code P0325 Knock Sensor. I have notice that this loss of power occurs when the fuel in the tank is below the 1/2 level. Do I need to...


Hi, first check the connector on the knock sensor. If the connector looks good and tight, replace the sensor. This should clear the trouble code and restore some power. If the car continues to lack power, check the fuel pressure at the fuel rail on top of the engine. If the pressure is under 40 psi, replace the fuel filter and check the pressure again. If the pressure is low after replacing the filter, replace the fuel pump. Please let me know if you have more questions, and thanks for using fixYa.

Sounds like itr is not getting enough fuel. Try or check the fuel filter for dirt or water, and also check the fuel pump pressure to see if it meet factory specs.
