Question about 1999 Pontiac Montana
There are 2 very important tests you must run here to get to the bottom of this problem, 1st, have the electronic engine control system (known as the OBD 2) tested for trouble codes, this is key to finding out if any part in the system has failed and is causing this problem, if you are not in Calif any Autozone will run this test for free as well as other "Discount" auto parts stores like Kragen, the next thing to do is have the fuel pressure tested, this requires a special mechanical test gauge, it is cheaper to just have a shop test the fuel pressure than buy the tool, (about $50) do these 2 tests and I am sure you will find the cause of this problem in short order.
