It's been a while but let's see if I remember this stuff.

First, pump relay, it doesn't shut off till the key goes off, it is a 'pressure by-pass' style of pump, the pressure is maintained up to the motor full-time, when the pressure reaches a set point a relief valve allows the excess to go back to the tank in a return line.

Second, TPS, not likely, more likely would be the temp sensor telling the motor it's colder outside than it really is, causing it to go into 'cold start' mode, flooding the not cold-enough engine.

If you have spark then it can't be an ignition switch problem.

I would be looking for a sensor that is out of range, likely one that tells the engine temperature. Unfortunately the earlier diagnostic software didn't have the capacity to spare for things like sensors being out of range. Some of them can only be checked with a good Ohm meter and a reading across the sensor to ground. If the resistance is not with in a specified range, it's junk.

Best of luck.
