Buick Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry for the long wait
do you know what the fuel pressure is key ON engine OFF ?
does it have an injector pulse when cranking it over ?
any codes set in the computer ?
rip you off how so ?
takes a few minutes to type back to you please be patient
we need to ask alot of questions sometimes before we can give you an answer as many things can cause this issue
first off 10 PSI is way too low for fuel pressure for this engine
and with NO spark when cranking it over we need to see if we have a crank RPM reading in the computer when cranking it over with a scan tool
