truck won\'t start Was wondering if any of you guys could help. Got a 1990 Blazer. Truck will turn over strong but won't start. Thought either electrical or fuel. Got new battery, alternator, cap + rotor, + fuel filter. Also checked the fuse for fuel pump and seems o.k. Anybody got any ideas of what it could be? Could it be that fuel pump is not working anymore? Is this something that you can change yourself? Any help would be great. Thanks.
