What color is the spark? Spark should be Bluish/white for good spark. Spark that is Orange is Weak Spark and vehicle won't start.

Have you check fuel pressure, if fuel pressure low could cause no start.

Is your engine light on?

My vehicle was running rough, missing as I ecellerated. I just had the fuel tank reolaced and the fuel pump. Thinking this was the problem. However today when I went to start it, it will not start. The vehicle turns over but no spark to fire. Is there another sensor or control in the fuel system itself. What should I look for?

Was the check engine light on? Is there power to the coil? Have you checked the crank sensor?

Let me know.

Have you tried to reset the inertia switch? I had a 91 ford explorer and the switch tripped the explorer just died on me. I had to have it towed home. Broke out the book on it and started reading. Read about the inertia switch went down and sure enough reset it and stated right up.

Hello,

No the Cam Sensor will not shut down the fuel pump.

Check the Fuel Pump Relay in the Power Distribution Box in the Engine Compartment.

Also check the Inertia Fuel Shut Off Switch locate behind the Passenger Kick Panel.

1995 Ford Explorer XLT mileage: 160,000. Occasionally (seemingly as a random occurrence) my vehicle will not start. The engine cranks, but nothing happens. And then just out of the blue it will start. When it starts the car seems to run fine. No warning lights come on, everything in the car functions properly, no strange noises can be heard, etc. However, as soon as I stop it seem like it`s a russian rullet if the car wil start or not, some times it start like à clock, and somtimes it can take over an hour before it starts. I can usually get the car to start in the morning and after work but if I stop for 5 to 50 min to fill gass ore somthing, it will not start. When the car doesent start ther is no spark I the pluggs. The strange thing is that the only thing that I do is to tourn the egnition and if it doesen`t star I wil just keep on tourning and the car will start after when it feels like it. But it`s bugging me like hell that I can`t troust my own car. Of course, since this is a random, but somewhat common occurrence, this never happens when the car is at the service station. Therefore, the dealership has told me that they can't fix the problem if they don't know (or understand) what is wrong. Since I live in Norway the service station are more inn too europeen cars. I thought you could help me out so I could tell them what the problem is.. Please let me know what you think about my problem. Thanks for your help!

Don't know what engine you have.I am guessing it is a 4.0L.

Sounds like a crank sensor. They are notorious for running a few minutes when cold then shutting off the car. Or not starting after you turn it off for several hours when they cool off.
Most of the fords I have had crank sensors go out on. Just quit totally and no start until new one installed but. It does sound like a crank sensor problem.
You will have no spark when this sensor CPS goes out.

When I try to start my car, it cranks but it doesnt turn over. I think it is in the fuel injection system. I should be able to hear the system when I turn the key in the ON position, correct? I was wondering where all of the fuel injection components were located on my car so I can examine them.

You should be able to hear the fuel pump energize briefly, may be hard to hear so try sticking a funnel in the fuel fill tank and have someone turn the key.

Check for pressure at the fuel rail

Maybe there is no connection but I installed an alarm on my car, and since then, my car decides when it wants to start. It turns over but it sounds like it is not getting gas. I had a mechanic look at it but it started, and now I can not get it to start at all.

I thought that it was a fuel cutoff alarm, but it is an ignition kill. Sometimes I hear the fuel pump, and sometimes I don't. Is it possible that the fuel pump works periodically.

Sometimes after turning the engine off it will not start right away.
There is plenty of spark and cranks over fine. If I crank it over several times and it still will not start I let it set for a while ( sometimes a few minutes sometimes longer ) eventually it starts right up like nothing ever happened.
This only seems to happen once or twice every other day or about 1 time out of every 20 or 30 start ups.

It doesn't seem to matter if the engine is hot or cold, it can happen early in the morning or anytime while traveling. The first time it happened was first start up in the morning, it started fine, I drove about a mile and a half and turned it off. I came back out about 1 hour later and it would not start.
I turned it over several times and the let it set for about 30 minutes. I tried again and it fired right up just like nothing ever happened. No sputter no nothing.

Later that evening after driving it, starting and stopping many times during the day without a problem, it again would not start. After sitting for a short time maybe 3 or 4 minutes it started right up again.

PS
No one I have talked to seems to be able to help. THANKS !

I appreciate your help,
Thanks.

Ok you say it has spark but have you checked to see if spark is present when you are having the starting problems? Next time it won't start I would like you to have a philips screw driver handy and pull a spark plug wire off of a spark plug and put the screw driver in the end of it and put near metal (like the valve cover) then crank it and see if there is spark. Now I would like to know what has been done thus far? What all has been replaced and is the check engine light on? Get back to me and we will go from there.

Read the guide below, it will help

I checked for spark the very first time. Right after it would not start. There was fire at that time.
I put in a spare plug and grounded it to the engine There was very strong spark.

Other than wiggling relays and checking for bad connections I have not changed anything.

The local mechanic said it has to be broke down to show up on the error code.?
Nothing has been done other than that.

Ok have you checked the fuel pressure when it dies to see if there is fuel? If not get a can of throttle body cleaner and next time it won't start spray some into the throttle and see it starts. If it starts and dies then we will check for fuel pump or fuel pump relay or injection problems ok.
