1995 gmc jimmy 4.3 vortec engine having a hard time starting. Fuel problem?

Question:
I have a 1995 gmc jimmy. I have been having a hard time stating the truck for the past month. I was thinking the batter, alternator, or starter could have been the problem, but those things checked out fine. The problem is on the first initiial start up. it takes anywhere from 5 to 20 times to get it started. It would crank but not turn over. Once the vehicle gets started its fine the rest of the day, then the next day same problem. The last 3 days vehicle would not start at all. Yesterday I took off the air filter and sprayed a little starting fluid in and truck started right up and was fine the rest of the day. Today was hard to start, but a little easier to start than normal 3 tries and it was started. Does anyone know what this problem could be or sounds like? I know its a fuel issue just dont know what kind of fuel issue. Please help me.

Anyone know where to buy head gasket sets online or at least check prices?

GM fuel pumps are on a two second timer.
When you turn the key to "run" position, the fuel pump relay turns on the fuel pump for two seconds, then turns it off.

One thing you might try next time, is to cycle the key on-off-on-off-on-off, Then try to start it.

Why does my gas tank keep clicking the gas pump off when it's not full yet?

If it starts right up, replace your relay.

Hi, Does anyone have a good wiring diagram for a 1968 Ford Mustang?

A new filter couldn't hurt either. It's inside the frame rail below your seat. (under the truck)

DO you hold your KNOB?

turning over and cranking is the same thing.sounds like either the gas filter or the fuel pump isnt holding the pressure.take the gas cap and check it,to see if its holding the pressure.
