Loose connector? Who needs glowplugs.?

Sent from my phone that somebody didn't help me get.

You did clear the codes before retesting with a scantool right.????

check both connectors at the glow plug module

the connectors break and the glow plug module breaks causing the connector to not lock in. sometimes wires will pull out from the back of the connector too or dirt gets in the rubber seal. They are a pain, I avoid unplugging the gpcm at all costs.
