Longer cranking time
I only drive my 95 about once every 2 weeks the last couple times I drove it it takes about three times longer to fire up then usual like it's not getting enough fuel pump going out?

You probably should hook up a fuel pressure gauge, turn on the key and see what the pressure reads. On my L98 the pump will pressurize the system a little for about 10 seconds. When you start cranking the engine my pressure goes up to about 42 PSI. When the car is running at that 42 psi and I pinch the vacuum hose going to the regulator it drops to about 38 PSI. Now you know what your pressure is. Double check the specs for your engine. Once you turn off the engine, watch and see how long it takes for the pressure to drop. Mine drops about 10 PSI in about an hour or two. Down to zero in about 12 hours. If it drops too fast, you have a leak somewhere and that is where your fun starts. Could be a line, could be the regulator or you could have a leaking injector.

Here is questions, it when it's sits and the engine is cold hard to start, and not when the engine is hot?
If that's what it does it's usually fuel injections seals.
