Ours won't start when the outside temp is less than 50 degrees so I help it along with a shot of starter fluid (ether). The inverter control board that controls the glow plugs is inop and would cost $1400 bucks for a new one. I can use a lot of ether before I spend that much. Don't get carried away with the dosage, it's easy to blow something internally.

When I install a new fuel filter I hold the starter button in the off postion for about two minutes. When you first press it down it takes a few seconds for the fuel pump to start and it takes a few minutes for the pump to fill the filter. I haven't a clue how you could fill the fuel filter with fuel. Have you checked your oil level? Low oil could prevent it from starting.

Follow up on the Onan relays. The Onan part number is 307-1886. The Tyco number on the relays I replaced is V23134-A1052-C643.
Here is the trouble shooting Sequence I followed.
1:
Then you need to remove the top cover of the genset.
Above the air intake are 3 relays.

Find the one that has all the wiring marked K2XXXX

At that relay, test the wire at terminal number 30 for 12V - it should be present.

Next, jump 12V to terminal 85 and see if you hear the relay click.
If it does, test terminal 87a for 12V while the relay is activated - it should be hot.

Continuation of Onan troubleshooting

Step 2: If you hear the relay click from 30 to 85, but 87a is not hot, go to step 3.

Step 3:If the relay is activating when you apply 12V to pin 85, and there is voltage available at pin 30, then the problem is a bad relay.

You will need to replace it.

I hope this helps. It's all I know. Al

I had a problem with my Onan 7500 not starting. It turned over, and sometimes tried to start. I got a code 36, which says it is the fuel filter, or the air filter, and something else. I replaced the fuel filter, checked the air filter, etc, etc. Finally I pulled the diesel line that goes into the fuel pump, put my finger over the fuel pump stub, and barely got any suction when my wife pushed the prime button down. I had to use my dremel to ream out the hole to get the bolts holding the fuel pump in, but, after replacing the fuel pump, everything works fine. Make sure you really tighten the fuel line clamps.
