you say it isnt starting at all? 1st simple thing is check fuel pump fuse then if thats ok there should be a valve on the fuel rail where you can test the pressure also could be bad gas, i had a surging issue once before and used iso heat or something like that for gas treatment (watered down old etc) surging can also be a vac line so check those. hopefully one of those will work for ya...oh s the check engine light on?
