Re: Engine turns but wont start
Check the key that year modle has a chip in the key and if it was around something magnetic it could have lost it's programing. If that is not it the there is a fuel rail with what looks like a air pressure valve. turn the key on and press that valve if fuel sprays out it is your key. If fuel doesn't spray the it is your pump

This is a devious problem which could lie anywhere. So many things not functioning would perhaps be a ground problem. Maybe take some extra care in cleaning the battery terminals, check if the ground wire is connected to the chassis. Do you have rodents in your area? Maybe they nibbled some wire somewhere?
Check fuel pressure. From what your explaining that is what it sounds like. Should be around 30psi and hold. Very common problem for any car that is parked overnight or filled up with gas and then it doesnt start the next day.
I would start with the fuel pump relay. The relay may not be working which would require the engine be cranked for a long time to get fuel pressure. You could also have a problem with the venting of the gas tank.
Sounds like your Interlock switch on the Brake pedal switch or the linkage in the shift cable is out of time. Check brakelights.
There was a problem in vehicle lurching when started. There were 2 different ideas to solve this. One system would allow the starter to work and the engine to run, but made shifting out of Park impossible without a foot on the brake. The other system required the foot on the brake and this signal would allow the starter solenoid to get a pulse from the Ignition switch. Some required the Gearshift to be in Park or Neutral before the brake signal could clear the Ignition and provide a pulse.
So your brake pedal switch probably is out of position or broken. If it is good, then the Gearshift position must be slightly off.
Also check the small wires on the solenoid to see if Voltage is present whenkey is turned to start and foot on brake.
I have exactly the same problem started last winter, ran fine all summer then as soon as it got below freezing again if I start it and run for 15 20 minutes wont restart I have to let it sit for 20 minutes or so and then it will start again. no codes and just turns over without starting. cant be fuel pump like i said had this problem last winter then ran fine all spring summer and fall! Anybody got the answer for this one??
