Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** is the fuel pressure reading your getting?
The fuel injection could not cause low pressure, the only other thing would be wiring/connection problem. I'd monitor power/ground at fuel pump, if pump maintains steady voltage and ground then replace the pump. Let me know how it goes or if you have more questions. Thanks.
No problem, let me know how it turns out. Thanks again and have a great day!
