Suzuki: Fuel problem, suzuki sidekick, fuel pressure

Question
I got 93 suzuki sidekick that has starting problem,it keep's on cranking and it wouldnt start. It has spark but fuel is not geting in to the trotlr body. I replaced already fuel filter it turned on and died about 2 minuts later. What else is there to be cheked out?

Answer
The questions you will have to find answers to are:
is there fuel pressure?
Does the fuel pump shut off and cause it to die?
Is the injector still getting a signal?

You have to have a functioning pump, good fuel pressure, and functional pressure regulator, and the injector signal has to be there to deliver fuel.
