The car hasn't been starting. When i try to crank it; it rotates, but will not start. When I let the key go after trying to start it, It spits and sputters for about 4 or 5 seconds, like it wants to start. I have replaced the fuel filter and plugs. There is spark at the end of the plug wires. I don't know, can you have too weak of a spark? I have replaced the rotor and cap as well. Before it stopped running, I would have to lightly push the gas to keep it going smoothly. If I drove it normal; it would miss or something and want to stall. I have no idea what would make it want to start after I stop cranking on it, instead of while i crank it. The fuel filter is on right. The plugs are right and gapped properly. I've listened to the injectors and hear them clicking. I haven't checked the fuel pressure yet. I can hear the fuel pump come on, and it comes on when i hot wire it. Any information would be helpful. Thanks for your time.
