I have a 1995 Dodge caravan, it turns over but will not run. I have given it a tune up and sprayed starter fluid to the injectors and it starts but will not stay running. What else could I check?
Fuel filter, fuel pump sonds like it is not getting fuel. Because when you spray starter fluid in it, it started and ran on what little bit of starter fluid you sprayed it with.
Here are the most common causes of idle surge, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Since obviously you are getting spark, the next place to check is the fuel pump (can you hear it run when you turn the key on?) When did you last replace the filter?
