When it won't start try spraying a shot of starting fluid into the throttle body. If it runs a few seconds it's likely a bad fuel pump.
put a fuel pressure gauge on it to confirm a bad fuel pump.
A fuel pressure test is used to diagnoses fuel pump.
Have you changed the fuel filter?
It could do that. Or it could run fine and just run poorly for a day or two then be fine again for a while then act like it is out of fuel and go back to running fine. The only way to know for sure if the pump is bad is to have it pressure tested. They can attach a pressure gauge and turn on the key to see if the pump builds and maintains the proper amount of pressure. My mechanic did that for free.
More likely the relay is failing. When you switch the ignition on from cold you should hear the pump running to charge the system, this will start the car, if the main relay fails it will not continue running
Get a fuel pressure gauge and check fuel pressure while cranking.
More then likely the fuel rail pressure regulator diaphragm has worn out and the pump is good, it's a $20 part at auto zone. The regulator is intake manifold vacumme operated so raw gas will leak through the fuel regulator diaphragm and flood the engine intake manifold with raw fuel when the diaphragm fails. If it builds up to 25+ psi and holds 30 PSI after shut down the regulator is OK, then pull the vacumme line and see if it's full of raw gasoline.
Auto Zone Part # 800-127, price is $18.99 at my local store. Pay attention to the gauge psi pressure in the video, not the same ford vehicle but the fuel pressure should act the same way where it pumps up in relay click run spurts and cycle builds up to near 35+ psi before starting. Ford specs 36-40 psi running fuel pressure but they have a pressure sensor on the electric fuel pump that surge feeds the EFI fuel rail in pulses to protect the fuel pump.
It may not be the fuel pump or relay. On some Escorts if air flow is not detected the ECM will shut off the fuel pump. The inlet air temperature sensor "over heats". But a failed inlet air temperature sensor will do the same thing.
I suggest making sure that nothing is obstructing air flow through the airflow sensor and checking to make sure all of the inlet air hoses are connected and tight.
Secondly sometimes the ignition switch is failing to keep the circuit for the fuel pump energized. I'm not sure how common this is for Escorts, but I do know some other cars of the period that experience this because of dirty or worn contacts in the switch. I'm not talking about the lock! The switch bolts onto the back of the actual ignition lock and is separate.
Hi yes so time to be asking yourself is it really worth fixing it now some 21 years old.
- Why doe my car start, sturtter, then die? I have a 2006 Ford freestyle, sometimes when I start it, it will stutter and die. When this happens all I have to do is give it some gas and it will start just fine. Is this a problem with the fuel pump? Or something else?
- Why did my car start and die when put into gear? Now it won't start at all? It's a cold winter day (below zero) Car started right up! I let it run for about 2 minutes, I put it in gear and it just died. I figured it's cold out, not real surprising, but when I tried to start it again, it won't start! Turns over fine but engie won't start! Any ideas? 2003 Ford Taurus 3.0L
- Why would my 98 mustang run for 45 seconds and quit running? It's got a new PCM that has been flashed or whatever from a ford dealership, keys have been programmed, new plugs and wires, new coil packs, new battery, new battery connectors, used CCRM, new intake manifold, new fuel pump with fuel pump assembly, and a new fuel filter
- On my 2000 ford mustang why does my air pump (smog pump) only blow air for 5 seconds after start up? Is that normal? I have p0411 secondary air injection system insufficient flow detected. I've checked the hose that comes out from the pump, it's blowing air but I believe it should blow air for much longer than 5 seconds on start up.
