1999 ford contour sport se 106k miles engine will start idle for 5 min. then dies but doesn't restart. Sign In

I have a 1999 ford contour sport se 2.5l duratec 24v dohc 106k miles automatic with OD
I purchased this car one year ago 2 weeks later it started bucking and missing it would die and then start back after about 10 miutes as long as it was sitting level wouldn't start on any type of slope had it obd diagnosed come back p0401 which I was told was the egr insufficent flow replaced entire egr system and cleaned throttle body and all egr passages. No change still had the same symtoms. Had it obd diagnosed again then it showed insufficent fuel flow and low fuel rail pressure. I got In the car one day for work it started fine let it idle and warm up for a minute was still running good soon as I put it in gear it quit tryed restarting it no luck. All it would do was turn over there was still fire on the coil pack let it sit a couple days changed the fuel filter it started with no problem idled fine and had no hesitation or cut out while giving it a little throttle then after about five minutes it started idleing low then quit tryed to restart it and no luck and there was still fire on the coil pack I had someone turn the switch on while i listened underneath for the fuel pump i could hear it kick on then go away after about 2 seconds it sounded to be fine couple days later tryed starting it and again it started fine idled fine gave it a little throttle and it done good but again after about 5 minutes it quit again and of course wouldn't start back and there was still fire on the coil pack. I checked the coil pack each time by checking for a blue spark on each wire. I have always thought that a fuel pump either works or it don't. Could the culprit possibly be my fuel pump or the fuel pump relay fuse under the hood. Any helpfull information will be appricated

That code has nothing to do your starting problem.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.



Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.



Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Apparently you didn't read my post then you would know that I have checked for spark the basics have been done that does not help me at all I need to know if a failing fuel pump or a bad fuel pump relay fuse would cause the symptoms I am having with the car starting for 5 minutes then quiting and not starting back until it sits for a day or two
THANKYOU

I believe HT read your post just fine and gave you some professional advice; advice if followed will find the issue and likely save you money.
Yes it could be the fuel pump; no it can't be a fuse, when a fuse bows it doesn't get better. Fuel pump relay possibly but very unlikely.
You've eliminated ignition because you've checked for spark.
So yea this is fuel related but what, lack of fuel pressure; no injector pulse; things need to be tested as to not replace good parts.
There's no black & white answer.
YOUR WELCOME!

Thank you Dan I appologize about sounding rude on the last post I had forgot to mention that I had the injectors and compression checked along with fuel pressure regulator they were all good can you still hear the fuel pump kick on if its bad and is it possible for the fuel pump to work correctly while cold then malfunction when it gets warm I ask this because I have always been told that a fuel pump either works or it don't
THANKS

As stated in my post, until you follow ALL of that testing during the failure, you aren't going to find your problem. This is the system we all use to isolate and troubleshoot a "crank, no start" problem.

As Ht Said you have to catch the gremlin when he sticks his head out.
Yes even though you can hear the pump run doesn't mean it will keep running properly, producing the proper pressure that is required.
I've had to drive these intermittent issued vehicles with fuel pressure gauge and other test equipment connected and visible through the windshield waiting for it to act up.
But if you're bound and bent going on a guess; I'd lay my money on the pump.
The dice are in your hands; it would be a shame if you crapped out.

Noticed from first post. Quote "it would die and then start back after about 10 miutes as long as it was sitting level wouldn't start on any type of slope<<"
There's a clue I think in that???? Do you absolutely know it has enough fuel?

If you want a better confirmation of the pump, you might want to have some shop that has a scope check the waveform on the pump. They can do that through the fuse and it can show a pump that is on the fringe while it is still working normally. Neat little trick that takes a few minutes, but you need access to a scope and someone who knows how to use it.

Ok thanks I will get the pump checked out and post back and let you know if the pump was the culprit. THANKS

Be careful when analyzing fuel pump current waveforms. Especially when doing ones on Ford returnless systems. The fuel pump module duty cycles the pump and you won't get the true waveform. You can run't the pump 100% duty cycle either on those systems because you could rupture the fuel pressure sensor.

I've seen new pumps show what a bad pump's waveform would look like, when they really aren't bad at all. Current ramping the fuel pump shouldn't be the definite reason for fuel pump replacement, but used as guide in troubleshooting. Not all pump waveforms shapes are the same, so it is hard to say ya or nay.

Judging from the diagram that I looked at, this car uses a regular, relay type circuit and doesn't have a FPDM.

Right, just pointing out that you have to be careful analyzing pump waveforms on those duty cycled pumps.

That's my point. I don't believe this one has a duty cycle pump.

You right, it doesn't. If it did, you would have to be careful about that. Had one the other day with low pressure and ramped the pump. Couldn't tell what was going on with it, because that system was returnless. It was the pump that was the problem, but it sure didn't show it on the waveform. Installed the new pump and mysteriously the waveforms looked very similar. Point being don't base your entire diagnose off one piece of information.

Look for lean code(s), low fuel pressure, and O2 voltage going lean at WOT.

Yes, a far as i can see this guy hasn't even used a fuel pressure gauge so everything here is just a WAG.

Well, if the fuel pump is causing a no start, a fuel pressure gauge reading during the no start would definitely point him in the right direction. If he would of followed your advice, he would have probably had it solved by now.
