1993 Chrysler Town and Country wont start

  • 152,000 MILES
Well yesterday I went out to the van to run down to the store. Needless to say it would not start, after it was running and has been running just fine I checked fuses and relays all looked good. So I turned the key listening for tge fuel pump to cut on andnothing. Turned the key back off and got my wife turn the ignition switch and I got right at the gas tank and still nothing. Replaced the fuel pump lol, and still nothing. Im lost, cant afford to take it in and we are suppose to drive accross country next week. Need some major help. Thanks

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.
