Question about 2000 Ford Windstar

1 Answer

2000 Ford Windstar, 3.8. Crank, no start. Believe fuel pump is bad, but when I tested voltage at pump harness, it shows 10-11 volts for 1-2 sec, then 5-6 volts as key is left on. Is this normal?

    BTW, I was checking voltage w/ positive lead in position 6, black lead in position 7. I also tried the black lead on body ground. Same results. I thought at first that the low constant voltage could be my problem, but further tests did show a 11+ volt current for 1 second. Got the same results at green/yellow wire at inertia switch. Looking more like just a plain bad fuel pump after all.

When you turn the key to the on position without starting the engine, you should hear the pump run for a few seconds.
If you don't, found out what terminals are the fuel pump on the pump itself and apply 12 volt power and ground. The pump should run. Pumps are expensive and sometimes a pain to install, so make sure it is bad before getting one. You could spend a couple hundred for nothing.
If your engine has injectors, you can check for fuel and pressure by finding a valve that looks similar to the one on your tire on the tube going to the injectors. Press the small pin inside and gas should come out. Be careful because of it is pressurized, it can spray you in the face.
If all the above is good, then the injectors are not firing. This could be a security lock-out if you had a recent dead battery and tried jump starting. You will need to follow the reset procedure to release the lock-out. If you still can not stay it, then you will need to follow the diagnostic procedure to find out why the injectors are not

    Thank you Don. I did check the pressure with an actual tester gauge from Autozone, and there was zero pressure on cranking. BTW, I did check spark too! Only thing I haven't done is apply 12 volts directly to those terminals because I was so reluctant about dropping the tank when if I could avoid it. Have to get 3/4 tank of gas out of it.

    BTW, I cannot hear pump sound at all, but then I never could when it was working too. When I get this fixed, I'm going to train myself to listen to it! :)

SOURCE: 2000 ford windstar won't crank over,but pats keys good, and batt.

First thing I would check is to see if you have power at the trigger wire of the starter motor while someone is trying to start the vehicle for you. It will be a Yellow with a light blue trace. If you do then I would check to see if the main battery cable has power to it all the time when someone is trying to crank it. If it does then I would hold a test light on the case of the starter motor and have someone try to crank it. Make sure that the ground you use for this test is on the negative battery terminal not just anywhere on the car. If the test light lights while you are cranking it then you have a bad ground. Hook up a set of jumper cables from the battery negative terminal and clamp it directly on to your starter motor and see if it starts. If you check it and the test light doesn't light up and all the other checks are good then your starter motor has failed. If one of the other tests has failed then you have a starter relay problem or something else. let me know what you find out.

You may have a break in the wire inside the tank to the fuel pump. I have seen the wires disconnect as the pump is installed.

SOURCE: Low voltage

what is the condition of the battery cables you are probably onto something about a ground but i dont think your ground issue is going to be at the batteries you may not have a good ground on the alternator. The next thing I would check is ... the alternator itself do you know that you are getting between 13.6 and 14.2 volts out of the alternator, a under charge or a overcharge condition both are bad for batteries.

I would check alternator output first if it is not within the above range you need to replace it

If the alternator is putting out in the range of 13.6 to 14.2 then you need to look elsewhere... you may have something draing the batteries overtime interior lights, electric brake controller for trailor brakes if equipped sound system if anything is getting power without going through a switched circuit this could also be your cause.

hope this helps

2000 Pontiac Grand am Replaced fuel pump today. Nothing no fuel pressure when I crank it. I check volts at the fuel pump plug in I get 4.9 volts. Shouldn't it be 12 volts. Can someone answer this.

yes. It should be 12 volts. Did you use the replacement harness you should have gotten with the pump? GM has an issue with the harness going bad at the pump that's why new pumps come with a new harness. Also check the relay.

Need to test for voltage drop at the ground and feed sides of the relay and at the pump. At 15 years of age corrosion can cause problems.

Where is the inertia switch located on a 1999 Dodge Durango

I don't believe it has one. I've heard some pretty reliable sources say this safety switch is a Ford-only product. First check the fuel pump fuse. It's fuse #1 in the Power Distribution Center, a 20 amp fuse.

If the fuel pump in the tank is not turning on to put gas up to the engine, you have a problem in the pump circuit or a bad pump.
There's an easy way to determine which it is. You will need a voltmeter or at least a test light.
Find the gas tank electrical connector. It will be near the tank. A wire loom of about 4 wires will likely come from the top of the tank and run down to an electrical connector, probably close to the side frame rails. Pull the connector apart, and on the harness side (or chassis side, not the tank side of connector) identify the dark green with black stripe wire in the connector. This is the power wire to the fuel pump. You need to check if it has voltage on it when the pump is supposed to be running and pumping.
You will need a helper to turn the key to start and crank the engine over while you check for power with the voltmeter or test light. If the voltmeter says battery voltage-right around 12 volts, 11.8 volts or more- or if the test light comes on brightly, then you know the pump has failed (90% certainty) and you need to replace it.
If there is no voltage on the dark green/ black stripe wire with the engine cranking, it is not a pump problem. You will need to consult a wiring diagram to diagnose the fuel pump circuit. I just looked and there is no inertia switch.
Good luck.

Not enough power to fuel pump

The 7 volts tells you your dropping the other
5.6 volts somewhere

Check the entire circuit with the problem for
voltage drops to ground or poor grounding

Pretty much need a wiring diagram to even
start on it

How do you check if there is power to the fuel pump on 2000 ford windstar. should there be power to the fuel pump shut off switch when checked with a test light?

yes. power comes from the fuel pump relay to that switch then to the pump Of course the wire will only have power in the crank mode, or for 2 seconds when key is turned to ON.

I have a 2000 Ford Windstar. My problem is it will not start sometimes. I can crank it over it starts for a sec then dies. The only way I can keep it running is by keeping my foot on the gas pedal. please...

sounds like a fuel regulator or fule pump. your going to have to test the fuel pressure the port to hook a pressure tester is on the fuel rail. anything below 35-40psi you will need  to prob replace regulator
