97 Deville Concourse having problems
 

Hello, first time to the forum. For the last six months I have had problems with the car starting but would run great once it did start. Just recently it shows Service Fuel System so I bought some fuel cleaner and added, once i did that it would not start again. I took it in to the service center and they told me it was the fuel pump, so they replaced the fuel pump assembly and filter. Now that I got the car back it is doing the same thing as before I added the cleaner. So I have a car that still needs fixed and out $600.00. Thanks for any help on this.
