Hello, Last week i was leaving my house when, i get into my explorer and it starts up. i load my kid into the car and we take off. i get not even a mile from my house and it shuts off on me so i pull over into someones driveway. Now my car will not start at all. the engine turns or try to turn over. it just revs and revs but wont start. i tried putting more gas in it. ive tried jumping it. but all to no success. i have had a little trouble in the past with it shutting off on me when i would stop but it was because it was idleing low and i had that adjusted. any help on what it could be would be great. me and my friends all are thinking its a fule filter related problem . because one thing we did notice was that from all the attempts to start the car we never smelled any gas up front in the engine. but we did notice when someone was at the back of the car you could smell gas slightly. again any help would be great. this is my only car and i need to get it running again. ty

Do you have a Jimmy or do you have an Explorer. It can't be both.
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 test 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 injecter pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injecter 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.
