Engine cranks but wont catch

try resetting security system or another key. your diode may be worn on that one. a new one wont work as it will need to be programmed to your car.

There is no security system and it is a standard ignition key. It started fine the first time, without a jump. I do not think it is the key. It almost fully started after a plug was pulled out and plugged back in to the air filter cover. Maybe a compression issue?

well there is a security system on it through the key even though it does not look like it. have it scanned for codes by a mechanic.

Sometimes when you put a new battery in it can blow a fuse, also did you happen to jump it backwards? this will fry the computer, here is a guide so you can do some more checking

Check the fuel pressure as well. The pump may have went out.
