Re: Mysterious fuel issue
Voltage drop... I'd check the battery terminals. Could be loose enough to limit available current to run things.
I had a similar problem. Thought it was water in the gas. Was intermittent misfire, making the truck 'chug' until I 'babied' it through its tantrum. Was old bad plug wires. Checked the old ones on the shelf in the basement, found 4 that were decent. Installed. Success.
Meanwhile, I had R&R's the injectors, the plugs, the TFI, and more searching for a solution. Set the timing incorrectly even, and it ran even worse. Finally checked the resistance of the plug wires. Some were infinite. Open, no conductivity. Spark would have had to jump several gaps to get to the spark plug. The symptom was so intermittent(must have a good TFI & coil???) it made no sense.
Check.
The battery cable thing can make stuff start to quit, such as the radio will shut off, the wipers start to slow down, the lights get dimmer, and finally the engine won't run. Well, it may run terribly, and have little power. Grabbed the terminals(not corroded, I maintain them) and I could move them. Oops. Wrenched tight, while waiting for spouse to come help. She arrived with jumper cables, but I didn't need them.
CHeck.
