Strangest thing....the GC has always started right up and now just cranks but will not fire.

Yesterday morning we backed it out of the garage and hooked it up to the motor home and took off for our summer trip. Towed it yesterday and again today without trying to start it. After we hit this campground in NV I decided to start it and let it run a bit to recharge the battery...it drains a bit for the brake lights.

Reached in and no fire, couldn't believe it and cranked it a few time hoping for at lease a pop, no dice. Fuel is full and it's run perfect since we've had it.

Gotta be something simple but I have no idea where to start so I'm reaching out for help.

Any thoughts would be appreciated.

The first thing to check is the condition of the battery. It may have enough juice to crank the engine, but not enough to also supply the fuel pump and ignition.

Battery is fine. I did drain it down in my attempts to start it but even after recharging it still just "spins" without one pop.

Any other thoughts.

Could be a crank sensor, cam sensor, fuel pump, it's hard to say without having done any diagnostic work. Check for spark and check for fuel. A simple way to check both at the same time is to shoot some staring fluid down the throttle body and try and start the engine. If it tries to start you have a fuel problem. If nothing happens you have a spark problem.

Thanks for you comments and it did get me thinking. The fact that it's completely dead had me focus on fuel delivery. When we got to the RV Park in Elko today I went blown fuse searching and in the process pulled the fuel pump relay, shook it a few time, banked it on the concrete 3X and reinserted.

Started right up. Not sure if it was the shaking or the banging but at least it's running. Now to buy a new one before the bigger hammer approach is no longer effective.
