Bad Glow Plug Relay?

Having a bit of an issue with Barney. Somtimes when I hit the key, the "wait to start" light doesnt come on. With that the glow plugs dont light. Are these two excluseive? If the relay is bad, does the light not come on?

Thanks yall! :thumb :

The light has no electrical connection with the relay, in fact, the relay is energized for a much longer period that the light shows.

The WTS light ON time is controlled by the PCM only. The PCM decides when, and how long, the light should be on depending on the sensors reporting to it. I'm really not sure what ALL the parameters are, but am sure it involves the EOT (engine oil temp) sensor at the very least....


When you don't get a WTS, does the engine still start? Because a "no-WTS" condition is often an indication that the PCMs not running then.

Good, that makes more sense to me then. It does it just now and then. Seems like it started when we put the chip in. Good stuff!

Take it out and clean your contacts some more. I used a brass brush(PHP suggests!) from the painting section of your hardware store... works way better than ANYTHING.. its very soft and wont hurt the contacts.

Yeah, I can pretty much 100% guarantee it is the chip connection. I had the same issue. No WTS and no crank when it was not making a good connection. Cleaned it a bit more and haven't had it happen since.

The very Best thing to clean edge connectors or even the legs if ICs themselves, is a simple pencil eraser
