SOURCE: will start then dies

On the regals they have a ceramic resistor on the passanger side under the fender. It heats up and over time it tends to brake and the wire inside tends to rust away. The fuel pumps run in 2 different speeds. Had the same problem. Dealer only part yet the car would run and you would think it was the fuel pump. Turn the key it kicks on then start and dies out. Ceramic on the pass side would need replaced. It is white about 2-3 inches long or so held on with 2 bolts i do believe. Ill find a bulliten i found online to help me diagnos the problem. :) hopefully this helps someone out instead of spendin $$$ that ya cant afford with the recession eh?

SOURCE: 92 Ford F150 4.9L. starts good, idles rough, dies at slow speeds

4.9 litre ?? you having a laugh its a 10ton truck engine not a pick up -global warming machine,remove the pump/sender unit and check the gauze filter also look inside tank for a something floating around ,i think the idles is not a related problem to the vehicle losing power but their is a possibility you could have a problem with the little vac operated thing on the fuel injector line that allows the fuel through only when the engine is running

My ranger 89 2.3 starts up idels way up then gos dead


Just before a car runs out of gas it will speed up the idle (rev up) backfire and then die. You are probably experiencing a lack of fuel. Put a pressure gauge on the fuel rail that goes to the fuel injectors. It should probably read between 5 and 15 lbs. If the pressure is bad, it could be a fuel pump or clogged fuel filter. Obviously it is cheaper to start by changing the filter. The line could also be clogged. If it has good pressure all the way up to the fuel rail, it could be clogged fuel injectors.

1994 Ford Ranger Starts runs for 3-4 minutes then dies, changed ignition mod, fuel pump, fuel filter, fuel pump relay,checked vac hoses, totally lost!!!!!


As with any no-start or stall problem you will need to figure out if it is a fuel or ignition issue.
The high idle usually means you have a vac leak or a problem with the throttle body or idle air control valve. The control valve is how the computer controls the idle speed.
You'll need to watch the fuel system and spark to see which is being affected when the engine dies.
You might want to hook a test light up to the coil to see if it is loosing voltage for example.

I would suspect that you have a failing fuel pump, the fuel pump pressure is bleeding off due to a faulty check valve, this causes hard starting esp when cold or after sitting. The fuel pump is located inside the fuel tank, the fuel tank must be removed to replace the fuel pump assembly.

1996 Ford Ranger won't start


I had the same problem , and if you read your book, it could be the fuel pump shut off switch, mine was bad and went from on to off position, its usually under the passenger side of the dash, look underneath at the "top" of the carpet, and you'll see a little red switch, check to see if the thing is plugged in , if it is , check to see if the switch is all the way down. i had to get a new one , sombody must have kicked mine and made it broken, but i got a new one and it worked fine

The mechanic should check on the idle .Because the Idle of the truck is adjusting by it self . That causes the truck to stop .check the Idle then lock it up to so that it will not adjust until it will make the truck stop .the main reason why the truck stop and pressure guage going down steadily is that no fuel enters the fuel pump when it adjust Idle by it self . It adjust by closing way or blocking the fuel to pass and go to the engine.then the engine dies .

You could have a slight vaccum leak that is preventing the fuel pressure regulator to operate correctly.

You fuel pump could be on the way out as well

You could have a crack in a fuel line

Have you changed your fuel filter?

Could be a couple of things, start there and see where it gets you.

Not starting..turns over but does not seem to want to start..New fuel pump..Someone told me it was an idle speed control motor


A relay, when jumpered will either close the pprimar circuit closing the secondary circuit and by passin either one will keep the fuel pump runing.. A t relay has two power sources going into it.. when the light circuit is closed it closes a heaveir circuit to handle the current draw of the fuel pum.allowing the pump to run. Yhe primary circuit is key actuated and when secondary engages ,iys oiwer is always present in the relay polug. in power is connected to the fuel pump wire when relay poibts close. On the fuel rail, there is s valve like a tir air stem remove screw on cap. rurn on key and then depress the vlalve center like letting air out od a tire. Yhat shoul purge any air in the system and confirm you are getting ful yp the injrcyors. I hop yjos helps. good luck
