ok i have a 1989 pont. 6000 3.1L mfi and a few weeks ago it started acting like it was runing out of fuel but i had just put about 5 gallions in it so tested the fuel for water & found none so i replaced the fuel filter and it seemed like it was ok for about 100 miles so then it would start then it seemed the fuel pump was not running so i replaced it & it ran erraticlly so tested the tps it was good but i had one so i replaced it and the iac too then it would run but when i accelarated it would die so i replaced the fuel pressure regulator and it drove fine but the there was a leak at the regulator seals so i replaced them now it won't start any ideas?
