Turn key forward listen for the fuel pump to pressurize if you don't here anything then your fuel pump needs replaced and it's in the tank.

I would start by changing the fuel filter. The next area would be the O-rings if so equipped. If it starts better after a short use then you are getting air in the fuel lines overnight. Diesels are tempermental. The cranking speed of the starter is important and easily checked externally. If you have a mechanical fuel pump you are relying on cranking speed to prime the fuel system. The timer or timing wiring could prevent the glowplugs from heating up. Diesels rely on glowplugs to start, then compression to run. Its a lot to look at but I suggested the cheapest fixes first.

Well, obviously someone didn't tell you the truth because spraying into intake doesn't make the vehicle turn over any better. You have ignition or fuel delivery problem. Start by taking fuel line off at intake and crank engine a couple times catching any gas in a cup or something. If none, then trace fuel line back and under vehicle til you find filter. Should be under driverside midway back on inside of frame. Change this and try test again. If no gas, see if fuel pump is on motor(mechanical pump). Change this and test again. If not on motor then it's in gas tank(electric pump). Most cases the tank has to be lowered to take out pump, careful not to drop, dent or make sparks. Some came with access through the floor so check that first. Normally you can hear an electric pump come on when you turn the key. Good Luck

On the inside trim, you can remove screws (these screws may be covered by filler pieces or may be visible, or they may require you pry a plastic piece off that covers the screws) that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect any other wiring that may be attached to the door.

Check the fuel pressure at the shredder valve, there should be 62 to 65 PSI when the ignition key is turned to the run position. (engine not running) Once the engine starts and is running, it should drop about 5 PSI. If the pressure is less then 62 PSI when the fuel line is pressurized, the engine will not start. If the pressure is good, then you may have a bad fuel Injection system which is a common problem to the CPI. Good luck and keep me posted.
