doc, the car does have a vats system, has the chip in the key with the orange wire with two white wires inside under the steering column going to the computer. I think i may just end up changing the fuel pump. its sounds to me like its that, but the fuel pump does continue to run while cranking the car. so lets go over this again, if the car fires with starting fluid, the timing is correct? we have spark? the injectors are firing? so the last and pretty much only option is the vats or fuel pump right?? just trying to clarify with myself, i got like 5 people telling me different things.
