94 xjs 2+2 Warm starting problem

Starts fine when cold but when warmed up it needs to crank a long time before starting but then runs fine. I replaced the front pressure regulator and injectors and it had no affect on it starting when warmed up. Otherwise the car runs great. What can I check next?

Try checking your crank angle sensor, they are known to work great cold but stall out engine when hot.

Never stalls out just hard to start
