don't know where the question went to but here goes again....I have a 2001 Pontiac Montana I replaced the cam semsors and the van ran for 3 weeks then cranked but did not start , we then replaced the fuel pump and it ran until i got it home then cranks and will not start , I sprayed starter fluid in it and it started and i can keep it going by pressing on the gas rapidly to get it to kick in , i checked the fuel pump and it is cycling i pulled off the filter front and back and i have flow...What would be the next step?
Sounds like a air leak. Spray around intake base gasket with carb and choke. Also have you disconnected battery for 5 minutes to reset and codes if any.
