Question about 1997 Buick LeSabre
I have two 1997 LeSabres and they both have between 130K and 140K miles. I just replaced fuel pump on one. So far everything that happens on one, happens to the other within a few months. Now it would appear the fuel pump may be going on the other and I'm about to take a 2,000 mile trip with it.
Why do you think its the fuel pump? hesitation caused by a few things usually simple and cheap to fix. vacuum leak ,check purge valve it has wire connect and to vacuum lines front and center of plastic upper intake. which will fail if never been replaced gaureteed coolent gets in the intake etc..known issue for the 3800 sieris 2 motor..around 150000 on average. one of your ignition coils which can be tested for free at auto part stores, tps , theres more but need more precise info to solve. if rpms randomly increase you may need to replace your iac .. idle air control . but not always the case .. before you do any thing make sure plugs and plug wires are ok and replace fuel filter. follow fuel lines near rear tire i think on this model its on the driver side.

Testimonial: "Vacuum leak was the key term suggested by philgoodno1. After replacing fuel filter and air flow sensor (probably due on a 15 yr old car anyway) the problem would seem to be "fixed", but that was because this vacuum junction part cooled off and the crack in it closed again. Short trips were OK. It was the interstate trips where the trouble (hesitation on acceleration) began again."
