2000 Chrysler 300m won't start.

(2000 Chrysler 300M)
I have a 2000 Chrysler 300m that ran absolute fine. then suddenly ran low rpms and died while sitting at a drivethrew. Now it won't start... Code said cylinders 5 and 6 multiple misfire. I changed spark plugs, didn't do anything. Tried starter fluid and it starts, then promptly dies. so I changed the fuel pump, didn't help. It has spark. And timing is still good. I don't know what els to look in to... Any ideas?

Thank you for your time.
Dan.

Absolutely sure it has enough gas in the tank? .. Just saying, I've fixed a pile of em by just adding gas that was supposed to have plenty in the tank already.... Guage might be lying! .. Also, when the engine starves for gas and stalls, all kind of codes can be set! .. Just something you should consider.

Still start and die on starting fluid?

Ya, with Out starter fluid it will just crank over. Spray a little, starts right up and runs for 4-6 seconds then dies.

Next test is fuel pressure with a test gauge and then injector pulse with a noid light... Good luck with it!

Fixed It!
I was going to look in to the crank sensor, cam sensor, PCM and the ASD relay. A friend had a parts car that I could use, so I started pulling one thing at a time. Turns out it was the ASD relay... Popped a new one in, cranked her over a few times and she fired right up. Thanks for trying to help me out guys.

Never seen a ASD relay stop fuel delivery and not ignition spark since it sends power to ignition system also .. BUT.. glad you got it running!
