For the past two months I’ve been doing rust repairs in a garage, finally got done today and the car won’t stay on. It does start, but stalls after a short amount of time. We’ve tried motor starter but it barely wants to start now. Fuel pump was replaced a couple months ago, please help if you have any ideas what to do.

 

If it starts but then stumbles and dies, check for air leaks after the MAFS, or the MAFS itself may be failing. Secondary, fuel pressure may be the issue...
