Need a little trouble shooting. Camper broke down today on the way to our last trip of the season. Driving fine then all of sudden two backfires and engine shut down. Coasted to a stop on the side of the road. Had minimal tools to diagnose anything. After pulling over tried to crank engine over again and nothing. Did check for spark which we had. Didn’t get a chance to check if we were getting fuel. Pregnant wife and a nice sheriff had the rig on truck and towing it back home before I had a chance to mess around with it anymore. Any chance it would be fuel? Working with remanded S&J engine. No upgrades or anything.
Jimmy,
Many of us have been there.
As it is a 75 and hence HEI, that would be my first checks, but you say you had spark.
Unfortunately, with HEI, it can recover in the time it takes you to get to the engine room. (BTDT, but not my coach)
So, in the morning run the whole diagnostic and if you still have questions, we are here to help.
Sudden shutdowns are common on HEI failures. This is why I suggest that all carry the complete kit. It is not difficult to install, but I have seen every single part fail (module, pick-up and coil) These are not big or expensive parts and do not require special tools.
Sudden shutdowns can happen with fuel system failures, but they are not common. They are usually proceeded by a succinct loss of power. You did not mention that. So, in the morning go out and pop the air filter and stroke the throttle and see if the accelerator pump spits fuel.
With a recent rebuild, it doesn't sound bad.
