vehicle: '95 LS

I've been trying to deal with a code 43 for the longest time. It's a fuel system problem. I've replaced the 02 (3 times), the fpr, injectors, fuel filter, and now have a walbro pump. An ecu is next on the list. The problem started after I removed my air bag; might just be a coincidence.

I've noticed that after I shut off the car, the fp drops to zero w/i a couple seconds. I believe fuel pressure should stay up for a little while. My fp guage shows around 42psi when the engine is running. I have no clue what the problem might be. Anyone have pictures around the fuel filter area. I just wanted to make sure that nothing is missing that's causing the problem. Thanks.

 

anyone have pics near their fuel filter?

 

just an idea but if you are dropping pressure think may it could be fpr. i don't know how they act when they go bad but. i have noticed that they do go pretty often.

 

I've changed the fpr already, but I still have the same problem.
