Question about 1998 Ford Explorer
There are 3 basic components that enable an internal combustion engine to run.
3. Ignition or spark
if any of these 3 items are missing the vehicle will not run. I doubt that air is the problem. To me the most likely problem would be fuel. In skynyrd74's case the problem could be the fuel pump, the fuel pump relay, or the injector system itself. To check this you could take a can of starting fluid and squirt very little of it into the plenum of the vehicle and crank it over and see if it fires. DO NOT SQUIRT A LOT INTO THE PLENUM!!!!!! IT CAN CAUSE DAMAGE TO THE ENGINE!!!!!!!! this is just to see if it will fire. If it does then the problem is somewhere in the fuel system itself and will need to be diagnosed with the proper test equipment and proper test procedures. If you are a DIY'er get a service manual and go through the procedures outlined in the manual for a no-start fuel problem.
If the starting fluid doesn't get it to "puff" or act like it is going to fire, the problem could be in you ignition system. in this case you would need to consult a manual or take to your local service professional for repair because there are many causes for a no-spark condition. DO NOT TRY TO TEST THE SPARK YOURSELF!!!! the ignition system on today's vehicles are extremely high voltage and can cause physical harm or death. DO NOT ATTEMPT THIS YOURSELF!!!!!! I hope this will get you started in the right direction. There are many other factors that will cause a no-start condition but these are the basics to making an engine run and in no way should you attempt repairs if you do not have experience in automotive service. I assume no responsibility whatsoever for any injury that anyone would have happen to them or for any damage to any vehicle by attempting the repairs themselves. You should always take your vehicle to an authorized service center for any repairs.
