So it turned out the fuel pump was dead so it was replaced with a stock replacement. Thanks for the input/guidance
However, a new problem surfaced. After the mechanic had finished putting everything together he let it run for at least 15 minutes in the shop while he was doing some other odds and ends. He said the overflow tank was overflowing and the car was running hot. He said the fans didn't appear to be running. So he let it cool down and did it again with the a/c running and noticed the fans were running and the overflow tank didn't fill up. Took it for a test drive and at highway speeds (50+mph) it ran around 195*F and about 210*F around town (normal operating temps).
Drove it home last night 400miles and the temperature gauge stayed at a steady 190-200*F with no overheating issues. Although I did not just let it sit and replicate the problem.
Random event? Or possibly a bad thermostat like he was suggesting to me?
