Are you expecting us to guess what engine it has? Gas? diesel? Engine size? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Does it turn over normally when it's hot or does it sound like it's laboring to crank?

What engine? It's lacking fuel most likely. Check if it will react before that 1+1/2 hour while down and see if it will even sputter with starting fluid. If so concentrate on fuel issues starting with if you can even hear the fuel pump prime, take fuel pressure KOEO and later KOER for a clue, T

I guess everybody is assuming this is not a diesel. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Code G = 7.5L engine. Pressure specs are as follows............. 35-45 PSI (Pounds per Square Inch)Position the ignition switch and the A/C system in the off position. Install a fuel pressure gauge to the vehicles fuel rail or fuel pressure test port.Confirm that no leaks are present, and visually verify the PSI reading on the gauge with the ignition in the on position. ******************* T

You wouldn't hear it in "acc" position ever. Key On Engine Off or KOEO is just the run position before it cranks the starter and where it ends up when you let go. It might be hard to hear at all depending on area noise. Doesn't matter if you are watching pressure it would power up for a couple seconds and show pressure that should hold without cranking engine at all. If much lower than spec it would struggle or not start. If within spec and doesn't start then injectors probably are not getting a pulse to do their thing. If no pressure during that time we need to think of what could do that based on time? Try to narrow it down to find exact reason as several things could be the problem, T
