You can get a fuel pressure checker for around 40 to 50 bux at a auto parts store.Should have about 39 psi.There is a shrader valve on the fuel rail to test from.

I had a wife one time and she also took a couple of times to get her started found out her ground wire was loose. Check for a good ground. Make sure all grounding connections are tight and no corrision.

Def sounds like the fuel pump is going..Mine was doing the same thing so I replaced the pump with one from autozone ( I believe its the pump for a 93 jeep wrangler with the 4 cyl engine.) things runs perfect now.

You can rent a fuel pump gauge for free at autozone.. They require a 140 dollar deposit but your money is fully refunded when you return the pump.. I was going to buy a 40.00 tester until they told me I could just rent theirs. Its a much nicer tester then the cheap ones also..
