95 jetta 2.0L 5 spd. Car has always been a pain - if it didn't start the first time, usually did the second, but I always had to turn hard on the key to get it to start - if not, it just cranked and cranked. Now it sounds different when it's turning over. There is no spark and the fuel pump doesn't stay on for more than a split second when key is turned on. I jumpered the fuel pump relay and I hear the fuel pump buzz and I checked the red/white wire at the pump connector and I see 12v. If I put the relay back in and turn key on, there is no volts on red/white wire, but 4.5v on the purple/blk wire. Pump is not working with relay in fuse block, but relay checks out good. Plus there is no power to the coil. What could possibly control both fuel and spark to this engine? The car cranks fine, so does that rule out my ignition switch or does that send power to the coil also. I'm willing to replace it, but I wish I knew what signals it sent out so I wasn't "easter egging" this problem. Thanks for any input.
