Question about 1992 Buick LeSabre
Ca1992 buick lesabre when it's cold it will run but if tyou shut it off after it warms up it wont start ..i changed the fual filter and checked for spark it has spark also fual pressure is 45 psi
Spark and fuel pressure at the times while it not starting? I hope so.
Will it start if you spray carb cleaner in the intake? If so we are dealing with an Injector issue Several injectors could be failing when hot It's very common also you need to hae a NOID light to verify that the injectors are being PULSED by the ECM if you have NOID and spark and fuel pressure then the only thing to do is while its stone cold. OHM all the fuel injectors and record all the reading for each cylinder.
Drive it then once it will not start, quickly do the ohms test again and record all readings again and any readings that are lower are likely bad injector windings and you need new injectors.
