i have the van listed above, it was misfiring and giving codes of p0300, p0203 and p0303. If remember correctly it had something to do with the fuel injector wiring. I changed out the wiring harness for the fuel injectors and now it won't fire. I tested the spark plug for spark and it is there. The plugs were wet so it seems to have fuel. It was running before the harness swap, but poorly and now it won't fire. It has a new, strong battery, I replaced the cam position sensor and the coil pack and the relays seem to be okay. What do you think?
have the same problem?
