Crank but won't start

It could be the fuel pump but the only way to tell for sure is to test it and do a visual check of the entire fuel line. Start by thinking about changing the fuel filter. (When was the last time it was changed?) Second check the line for any leaks or kinks, even small ones can make a difference. You say you have plenty of line pressure but how do you know this? You will need a fuel pressure tester in order to make a few checks. After connecting the tester check that the pressure is with in specs for the car with it running. Then check that the presure is in specs after the car is turned off to make sure the pressure doesn't drop too much. Hope this helps Backyardmechanic
