My daughters 1997 Explorer cranks but will not start. The battery was run down attemping to start it. I bought a new battery and the next day the same thing happened. I also replaced the alternator since the new battery was run down due to continued attempts to try and start it. Yesterday I was told to remove the IAC valve and clean it with carb cleaner. I replaced it after cleaning and the truck still didn't start. I checked to see that fuel was present via the Schrader valve on the fuel rail and some gas did squirt out. I'm out of things to try and don't want to get ripped off by taking it to a Ford dealer. Any help will be greatly appreciated.

Hello,

Ok, you done the first thing check for fuel, so now did you check to see if you have Spark? If you can check fuel pressure. If need fuel pressure tester some parts stores or a tool rental store should have one.

Well, I would ask if the Check Engine Light was on but, since Battery was replaced codes were cleared and would have turned engine light off.

Did this Guy ever find out y his car would not start? I have one of the same 97 explore. Cranks but wont start. When I finally do get it to start it will start right up again after being turned off again butt if I wwait say an hour or more I have trouble starting it up again. I've replaced batety with brand new one. Nope not it. Replaced altanadtor with a rebuilt one. Now my battery light is on so I took it to auto zone who said my altanator was bad. So I take it BK to altanator place they show me on two different machines its good. And tell me its a fuse under the hood. They replace it light went off and it drunk. Started and I go home only to get home and look to see fuse is blower again I Called altanator place who then had me disconnected wire in altanator to bypass fuse and well guess what. Nope. Might I ask if its against the law to set ur own car on fire. '''Joke ''' but I'm at my whits end here. Could this be my starter. Fuel pump. If ne one has ne idea please tell me.

1997 Ford Explorer 164K Fuel injection. This problem has been going on for a couple of months. Starting in the morning is no problem. After driving and engine is warm I can start it right back up if left under 30 min. But after that 7 out of 10 times it wont start. It will crank but not turn over. Very occasionally it will try to catch. If I leave it for an hour it will usually start back up or over night. Repair shop tested the fuel pressure and spark said it was ok. They decided it was the inertia switch and replaced it. Worked for 2 days then the problem was back. Obviously not the problem Any ideas? To reiterate problem occurs only when hot and around 30-45 mins after engine has been shut off.

Sure sounds like the fuel pressure is bleeding off. Need to have them do a bleed down test on the pump. At that mileage, I wouldnt be at all surprised if it needed a fuel pump. Any codes in the PCM?

No codes in the PCM(Was replaced and new engine 5 mo ago), can you tell me if there are any gaskets orings between the fuel pump and the injector manifold thst might be leaking and not allowing the fuel pressure to build high enough to open the injectors when hot/

The fuel pressure regulator, the pump or an injector are the only places the fuel pressure can bleed of at besides an external leak that you would have smelled by now. Pull the vacuum line off at the regulator to see if it has any fuel in it, if so replace the regulator

You can start by checking the basics. Check for spark while cranking. Check for fuel pressure. This will narrow down the problem to a more specific area.

If you suspect a key chip problem, you can take the VIN to a Ford dealer, and they can tell you if this vehicle uses a transponder key. If so, they can also look up the codes and cut and program a new key for you.

If you find that you only need an ordinary key, then it is back to the basics. Let me know what you find, and I can point you in a direction that will help you to solve the problem.

IF the car needs a transponder key, you can have it programmed at a dealer. Unfortunately, the machine need to program "chip keys" is expensive, so not many places have them.

First, be sure of what you need. If the car takes an ordinary key, and not a "chip key", then your problem is in the ingition or fuel circuits.

It sounds like the ignition module. Do you have the COP system?

No, it does not have COP. Do you still think ignition module?

It is the most common spark failure on Fords. I am not there to do some pin out testing but if all fuses are good and you have injector pulse then the module is your best bet. Good luck

Thanks for the advice. I'm sure I have injector pulse so I will go with ignition module and see what happens. I appreciate your time on this. Thank You

Lee, I'm being told that there is no ignition module for this year and that Ford stopped using these mid 90's. A dealer told this to me. Is he right and now where do I look?

He is right. CRS came upon me as the 97 is a stand alone system. It is EECV computer. Is it a V-6 or V-8?

The signal is developed in the crank and cam sensors and sent to the ECM. It in turn processes a signal to the coil packs to fire the coil packs and on to the right spark plugs. Have you tried to get the computer codes to see if you have set one. From my info the crank sensor is the highest failure item. Sorry for the confusion. Let me know
