Looking for a quick read on if I'm interpreting the troubleshooting instructions correctly. Have read through all the various threads, etc. Here's the specifics:
06 T1N passenger with aux heat, REST & 7 day timer. (Also rear heat)
ESPAR was working fine a year or more ago, but we don't use it much. Tried it recently, and it would not start. Here's the specifics:
- No codes on 7 day (no diag wire, yet)
- Interior fan comes on lowest (1) setting
- I think I hear the espar fan running
- Dosing pump clicks after a bit, 8-10 times. Then stops. Then a minute later does the same.
- No smoke, no roar, no noticeable fuel drips
- What I though was the circ pump was not running. (Up on firewall near blower resistor). Now I'm thinking that was not it, as most pics are different and lower.
Since it attempts to start, based on troubleshooting, it makes it sound like:
- It's not locked (no code on 7 day, and it tries to start)
- Not blower problem, as it tries to start
- Not coolant pump as it tries to start???
Likely suspects:
- No fuel
- Plugged air/exhausts
- Glow pin??? (hard to tell on that one)
I'm going to confirm fuel and no blockages.
But would greatly appreciate if any of you ESPAR savvy types could confirm my interpretation of the troubleshooting docs and results are correct. IE: Not locked up, not likely coolant pump, etc.
I'm going to crank the van and see if it will start then, which I think isolates out the coolant pump.
Any input appreciated!
