how can I measure the amount of fuel injected into a diesel engine in real time in a purely mechanic pre-OBD vehicle?
If the injectors are fired electrically(which they most likely are), you could wire in a voltage-switch to the injectors, so that it is closed when the injector is fired. This would allow you to measure the time spent open, and do a little math based on the flow-rate of the injector to get a calculated measurement of the fuel injected into the system. If they're fired mechanically, you could try to make some kind of sensor to read the state of the mechanical system, although that might be a little more interesting/complicated.

2003 Hyundai Santa Fe will start then die. Then it will not start. After pumping the accelerator or holding on the floor and returning later it will start. Nothing codes out. This happens probably 15% of the time. Any ideas?

A friend has an older Miata that was improperly stored for at least three years. Most of the time, it was not garaged. The gas is old, the battery is dead, it has not been started. It was probably parked without an oil change. He is looking to do the minimum to get this sellable, so the primary concern is the initial startup and the brakes. What would be recommended , especially regarding that first engine startup?

I’ve asked a few mechanics and DIYers this question and so far no consensus. Let’s say you’re 1000 miles away from next SCHEDULED oil change, and you’re about to leave on a 2000 mile road trip. Would you choose to change your oil 1000 miles early before the trip, or 1000 miles late after the trip?
