HELP! 99 durango had issues last winter cranking but not starting. Starting fluid would make it start. Also, if you hold the accelerator down, it will sometimes start. Replaced fuel pump. All summer, no problems. Now it is doing the same. Tried the air intake temp sensor. no change. any suggestions?

 

Maybe a vacum leak? TBS Sensor?

 

i would take a look at the iac (i seem to remember my old truck being hard to start at times until we replaced that, and holding the accelerator to start is a pretty common symptom of the iac) or the tps (throttle position sensor)

 

Remove the Throttle Body and clean every nook and cranny. Place a new gasket on and re-bolt. Clean or replace the IAC on the back of the Throttle Body. Do not push the IAC plunger in while cleaning. Or simply replace the sensor.
