Now it’s time to test the electrical system. But very first, Permit’s take a look at newer styles with variable velocity fuel pumps.
When fuel force is low, a scan tool will display extended-phrase fuel trim is noticeably good all the time and short-time period fuel trim will arrive at most on acceleration (fuel trims max out at 25%). Even so, a vacuum leak can make very similar fuel trim readings.
Last but not least, analyze the fuel alone. Can it be cloudy or discolored? Pour at the very least a cup of it onto a clear white rag or paper towel and find out what it looks like immediately after it dries out. Is there a fair tan stain or can it be a rainbow of colours?
