I have a 2000 Dodge Grand Caravan 3.0L front wheel drive. Was driving from Va. to Tx. Got about 4 hrs from texas, has the vehicle on cruise control and was driving on the highway at about 65mph. All of a sudden the vehicle is on but starts losing speed so I put on the gas and nothing happens. I pull over and let the vehicle sit for about 10 mins to cool a bit (my temp gage wasnt reading hot) and then fired the vehicle back up and moved it a little more off the highway (about a foot was all i tried to move it) and it moved but kind of jumped when i hit the gas petal.

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. 4) If all of these things check good, then you would need to do a complete compression test. Once you have determined which of these functions has dropped out, you will know which system is having the problem. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Hammer is absolutely right about the diagnostic procedure . If you wanted to try one throw of the dice, i would try a new fuel filter . Most vehicles are overdue for one so its not a waste of money . However if if this does not solve the problem then bite the bullet and stay with Hammers advice. LIFE'S SHORT GO FISH

I agree, fuel is very likely. There are other things that can knock a fuel pump out so you may have to do the testing in the end anyway. You have it if you need it. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
