Dodge Caravan No start issue
 

2005 Caravan,3.8.Ran fine yesterday with no issues.This morning it cranks fine but no start.Scanned it and got a P0688(ASD Relay Sense Circuit-Open) P0685(ASD Relay Circuit),P0443(Evap.Purge SolenoidCircuit),P0129(Barometric Press. out of Range-Low).I swapped the ASD Relay with the wiper(Wipers work)Relay,no change.Checked the ASD fuse and it was also good.Any ideas would be greatly appreciated.Thanks.

Welcome to DF
I have pdf files for the code that you have. Since you have a map sensor code, i would open up the wire harness near the p/s reservoir and inspect the wires. If you need the pdf file. Just post your email address or send me a pm.
