Sounds like you are loosing fuel pressure overnight. Since it takes 70+ psi to start and run, if you have zero pressure in the morning, it would take a long time of cranking to get the pressure back up.
If it is low or no pressure, the problem could be a faulty check valve in the fuel pump.

SOURCE: I have a 1995 GMC Jimmy that won't start.

It sounds like a faulty fuel pressure regulator. When you turn the key to the on position the fuel pump starts for an instant to build pressure in the fuel line. If the pressure regulator has allowed too much leakage since the last start then the fuel pump does not have enough time to prime the line. The fuel pressure will still measure ok when the car is running because the leakage is very low. Try turning the key off and on a few times prior to starting and see if the extra pump priming steps help. Also check the vacuum line to the regulator because it needs vacuum to work correctly.

look under the front of your blazer, just below the bumper, and you will see a little access door in the plastic guard. Open this door, and you will find your oil filter.

Starting issue in a 2001 gmc jimmy 4x4


MY opinion is the fuel pump pressure is low and allowing vapor in the lines that dissapates over time. But when you make short trips the fuel does not let the vapor out.

The first thing i would do is have the computer scanned for codes and see what codes are stored, you may have a bad fuelpump or a control module problem, check for fuel and spark, spray starting fluid into throtle and see if it starts if it does then you know its a fuel problem.
