try quick start straight into air intake or air filter housing while turning over <if it fires up for a few seconds its a fueling problem ,if not more than likely a spark related problem
Try gently moving the shifter around while cranking the engine (while in the park position). There is a sensor in the J-shift that will prevent the proper voltage from reaching the main computer if it is out of adjustment. This problem drove me nuts until I figured it out. I would start and run fine, then it was like the fuel pump went out. Good Luck (I know it's an old post but it might help someone)
The fuel has to be under pressure in the fuel rail. Quick check for the pressure: pinch off the fuel return line and get an assistant to crank the engine. If it starts....it needs a new check valve in the rail. Fuel is just circulating in a loop from the tank. No pressure being generated to enable fuel injectors to "fire".
If FP ok, then check the neutral sw in the trans selector hsng. if not operated when selector is in P or N engine will not start.
Check air flap in the throttle valve body is not stuck in open position. and is free to operate.The idle bleed /cold start valve needs the air flap to be operational.
Check connecting bellows between throttle body and inlet m'fold to ensure no air leaks. If leaking it will by-pass the control in the throttle body.
Not aware of your skills so for me to start getting into the other possibles would be a bit premature.
Check again, but spray a litle heavy oil in the low cylinders first, see the compression comes up. Try a brand new battery, sounds strange, but try it !!
easy way to check if its getting gas is to take off the breather hose and pour some gas in then put it back on before you try to start it if it starts or even try's too then its fuel pump
