I hear the fuel pump come on. The shop seems to think it is a electrical/wiring problem. But it does seem odd that it will start right up after sitting all night. But after sitting for 8 hours it will give problems. It always starts however, or it used to.

Get the fuel pressure checked out fuel pump could be failing, The best way to catch this when it refuses to start is do below it will tell you if its a fuel or spark problem

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

Hi,

I am having trouble with my car and I figured i'd try and get help.

Let me start off by saying, I have changed the fuses, distributor cap and wires, the brain fuel pump, & coil. I have a friend who said it could possibly be the injectors which I have yet to change. Anyways onto whats wrong with my car. For awhile it would run and randomly shut off when I would brake. As of now it wont start at all all my functions work like the radio, lights, ect. So any clue what is wrong with my car?

Two tests to run 1.) Check for spark
2.) Check for gas. Till you narrow it down you'll never figure it out.

1994 Ford Taurus 6 cyl Front Wheel Drive Automatic 160K miles

I started out to replace the water pump, and because of a stud that refused to come out, I had to go the long route and remove the timing chain cover and all of the other things that go with it. All of the replacements being in place, I am in the process of trying to start the car. I removed plug #1 and since you cannot get your finger or thumb in place to feel the compression at the top of the stroke, I used a small screwdriver to feel the top of the piston at the top of the stroke. At the same time, I assured that the pointer on the timing chain cover and the notch on the damper are in line and the rotor is pointing in the position of the #1 post on the distributor cap. In other words, by the book. It still won't start. Help

Was the chain replaced?

What do you have for engine size?

Pull back out the distributor
turn the crank one full revolution
install the distributor

I apologize for the missing info. It is as follows;

No, I did not replace the chain.
The engine is 3.8 V6
About the third part of your reply where you say pull the distributor and rotate the engine one full rev and then put the distributor back in; There are three things that I do according to the book. (1) Rotate the engine until the piston is at the top of the stroke. (2) Line up the arrow, which is cast-in as part of the timing chain cover, with the notch in the damper. (3) Line up the rotor tip with post #1 on the distributor cap. Now if I do all three, what will removing the distributor and turning the engine one full revolution and put the distributor back in do?

Over looked many myself
thinking its at power stroke and in fact is not

if you are sure that its on the power stroke just please ignore what I suggested

let go back to basic and check for fuel, spark and compression

A friend of mine has a 1994 Ford Taurus that turns over but won't start. I checked the fuel pressure on the fuel bar (getting 40psi) and checked ignition for fire (getting good fire). He replaced the black box on top of the radiator. Checked all fuses both inside cab and under hood. Any other suggestions? Thanks in advance.

You need 4 things for a car to start: gas, spark, compression, and timing.

You're getting gas and spark. The next step is to check your compression on at least 3 cylinders. If that passes, then check your timing.

The two main components that directly affect timing are the crankshaft position sensor and the camshaft position sensor.

I don't know if you are allowed to adjust the timing using a timing light - that is usually covered by the two sensors mentioned above.

I have a 1994 Ford Taurus (3.8) Fuel Injected V6 with about 81,000 miles on it. Recently I went to start the car to warm it up in the morning for work and it would not start. It sounded like it had a little bit of juice because I could hear it sounding like it wanted to start. The lights and everything were able to come on but it just wouldn't start. I ended up having it jumped and it started right up. Later on when I went to start up the car to leave work the same thing happened but this time it didn't sound like it wanted to start (less juice). When I gave up I noticed now the power (stereo, clock, door locks etc.) Would not work. My question is does this sound like a bad battery or an alternator problem?

I would say if you made it to work with a low battery the charging system should be working. Change battery.

But if my alternator was bad or going bad would it still allow me to jump the car to get it running? I didn't notice any signs of my battery being weak prior to this incident.

Sounds like the battery just failed, it's how most go away, a cell will short out or something along those lines, no warning. If the alt is bad the car will only run as long as the battery has enough volts to power it, hence reserve capacity number when you buy the battery, that number is theoretically the time your car will run with minimal accessories if the alt fails. If your jump=starting the car and it runs alright, but you still need jump, the battery is shot. A little tip, buy the most powerful cca and reserve capacity battery you can fit into your battery tray

Thanks for the knowledge and advice. Pretty much how it happened was I went to start the car in the morning so that I could warm it up as I got ready to leave for work and it wouldn't start. It made an errrrrr sound like it wanted to start but nothing. I had it jumped and it started right up and I ran a few errands before work. Leaving the car running just in case. Once I arrived at work I obviously had to kill it so I did and when I went to start it up to go home the same thing happened except it sounded like it had nothing left. When I went to lock the doors I realized there was no power to lock them unless I manually used my finger to press down the locks. The clock went off and radio was unable to come on as well. One thing I did notice was after I jumped it that morning my Anti Lock light lit up for some reason? I'm guessing because I jumped it something electronic happened? I had no problems with anything else, just that it was lit up. Anyway, from what i'm hearing i'm dealing with a dead battery. I just wanted to make sure it wasn't something else first that way I didn't waste money on a battery if it were the alternator or some sort of circuit.

Thanks again.

Engine Cranks, but does not Fire. Starts fine with Starting fluid, and idols for about 30 Seconds then stalls. I don't want it to be my fuel pump. Any other ideas?
