Ok I will clean those wires. Should I clean all 4 on the terminal? The. Put back turn power back on and test the way you described? If no reading what would next step be? Trying to verify power is going at all.

I don't know much about those timers so I'll guess that they are wired so there is no power to the heater unless the pump is running.
So once it is cleaned up, turn on the pump and check for voltage (AC) at the black and white wires on that block.

This is the pressure switch. It does look a bit corroded and you might want to think about replacing it unless of course you just decide that all of the work you are putting into this heater might not be worth is and purchase a newer one instead. Sometimes you end up spending lots of time and money on a unit that isn't worth repairing and then it's just time to bite the bullet and buy a new unit.
CarrolltonTXPool, with all the time you have invested in this it would have been cheaper for you to call a professional and have them look over the unit. If you schedule it right and you are there you could learn some valuable info as well. Sometimes you just have to do this. You might start down the wrong path to fixing this old unit and then find out that it has more issues then you thought.
Pool Clown said:I think i would replace that pressure switch, at least. That would sure explain the symptom, "Worked fine last winter and spring, Didn't use it through the summer and now it won't fire." Probably the least expensive part.
Or...
Only if you are comfortable doing this, jump that pressure switch TEMPORARILY! Only long enough to confirm the heater fires or doesn't (as soon as it fires, disconnect), then reconnect to the switch and continue with repair or troubleshooting.

Pool Clown said:Remove the two wires from the switch and connect them together.

I have had customers who are selling and instead of repairing it, they have me remove it and just loop the pipes together and cap the gas. Then they list as is and make no mention of a heater. Yes it might make some perspective buyers mad it doesn't have a heater but for some sellers its better to let the buyer foot the bill for a new one. Also, I read in your signature line, it looks like you just have a pool so a heater isn't really necessary. Let the buyer take care of it.
