What makes you so sure it's the relay?Have you checked the filter,fuel lines for bubbles,pressure at the injectors?

There is no in tank fuel pump, or fuel pump relay on your engine. No electric fuel pump at all.

So listen to Jason's questions.

Given the year of your car and possibility of it have a C or D level fuel sender and the temperature there right now,you may be experiencing geling

it died on me while i was driving about 2 weeks ago. i assumed it just gelled up on me, its done it before. so i replaced the fuel filter and waiting for a "nice day" (about 50 degrees) to try and start it. it will crank all day but wont start.

Did you break the "O" ring around the Thermostatic Tee when re-installing it,it happens and you won't even know it,I'd start there

Look closely at the sender,this unit not only transmits fuel level,it is also where the pick up is for the fuel filter,look close you'll see it

The little triangle section and a check valve,that is what gels up and prevents flow
