Picked up a used 2003 Vibe. Engine will crank over with no problem, just never starts. Previous owner told me it just stopped one day at the store, never started again. Have done the following: New plugs Fresh gas, verified pump operation. Tested all coils for spark, good. Cylinder compression ~180psi on all 4 cyls. Tried a spare PCM Replaced cam position sensor (had previously set P0340 code) Checked and rechecked crank position sensor and cam sensor. Checked timing chain and timing, perfect. Checked all grounds and battery/alt output. On prolonged cranking, there is a slight stumble, but never fires up. About ready to take it to the scrap yard.
It has good spark then? Have you pulled a plug or two after prolonged cranking to see if plugs are wet with gas? You said pump was working, have you checked the fuel pressure? Nothing in your comment about the injectors-that's why I asked if plugs were wet.
Check the fuse for injectors, verify that power is available at all injectors with key in ON. You can check the injector circuit with a "noid light" available at any parts store-different sizes, so get the one that fits your injector connector. Just plug the light in and crank the engine over. If circuit is good, the light will blink. If it doesn't blink or if it lights up and stays lit-the circuit is not right.
All of this is to see if injectors are pulsing and spraying fuel. Do the same with spraying starting fluid into the air intake and cranking motor. If engine now runs for a few seconds, then you know it was a fueling problem.

nutral safty switch try moving the shifter from P ... to N....P....N....P.....N
SOURCE: 04 Pontiac Vibe bad gas mileage without a code and then the p0420
that code is from having the plugs wires reversed as you did and the o2 senors regrsitered the overload on gas emmions once you remove the battery cables for about 5 minutes and then recconect and run the engine it should be okay
