If you have the spider fuel system, it is noted for problems. Use a fuel pressure gage, 60--66 psi, to get it to start.
Did you check for spark at the plugs? Any applicable trouble codes?
There have been service bulletins about cold start up problems, in the morning, after it starts it usually does fine the rest of the day, poppets need cleaning.

2004 gmc jimmy, tried to start fired twice didnt catch now just turns over,i can here fuel pump and smell gas.replaced ignition coil??? still wont fire


Check the ECM/BAT fuse. this fuse controls the ECM and the fuel injection circuit. If the fuse is ok, you need to check for voltage at the spark plug. Pull the #1 spark plug. If the cylinder is getting fuel the plug will be wet with gasoline. Put the spark plug wire back on the plug. Now crank the starter and look for a spark from the spark plug electrode. If you can let me know what you find from these tests, I can help you determine the next course of action.

1997 GMC Jimmy will not start! Prior problems!


Fuel pump. Listen for sound of pump when you first turn key. Have someone listen at tank when you first turn key. Costly part but most successful fix for most fuel problems.

Only starts when cold


I'm not familiar with your truck but this sounds like a cold-start valve that is stuck and allowing excessive gasoline into the intake system. If this is the case, you probably have miserable gas mileage right now since the engine would be running rich continuously.
Starting it warm, probably is causing some mild flooding and getting the plugs wet so they can't fire.
Try this: with the engine hot/warm; press the accelerator slowly all the way down, then try starting it. If it starts this way, this would be an indication that the engine is getting too much fuel for its temperature and opening the air supply fully helps to change the air-fuel ratio sufficiently to allow it to start.
