I'm having trouble starting my 89 base T-Bird. I sprayed some starter fluid in the intake and it runs for 2 secs and dies. A mechanic pushed down on the fuel rail valve stem and some gas came out but he said it wasn't enough pressure. He said the fuel pump is bad, and $180 for labor.There is another v6 bird I can get parts off of to help my car get going. Hopefully if I change the fuel filter it will fix the problem. Is there anything else I should look for?
