Pressure Fuel

How can I test a fuel pressure regulator if the car does not start?

I took the car to a mechanic yesterday who said the fuel pump was bad. I'm assuming he said this because there wasn't enough fuel pressure. I am still having the same stalling issues. I have read the fuel pressure regulator can cause this. I have personally replaced alot of other parts to rule out electrical problem. Any advise on how to test the fuel pressure reg will be appreciated. thanks.

first thing is fuel injection or carburetor?

assuming is FI you have to cut the outlet fuel hose and place a fuel pressure gauge there if it is higher than 20psi then is bad your regulator but.... it can be different psi depend on the engine and brand of the car

buy the repair manual of your car it should say what is the correct psi at the inlet and the outside fuel line

is very weird in FI system get a broken fuel regulator (unless you have work on it) they are mechanical and cant be adjusted so... they will work ever at the same pressure if your car dont start is still an electrical issue

what could be wrong if you are not getting good enough fuel pressure?

may not have enough fuel pressure to get it started
what should i look at or for and what should i do.

Before you start throwing parts at it, if the engine isnt starting it could be a lot of different things. About the only thing to do is bring it to a shop, and have someone check it out. I wouldnt put a fuel pump on it, till I knew that was the problem.
