Use a gage and check fuel pressure. Check the tps. Any applicable mil codes? You can check mil codes, yourself. You use a jumper wire between the A & B terminals at the datalink connector. Turn the key just till the dash lites come on, no further. The mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes. Let us know what you find.
