fuel pressure
 
94 yj 4.0 On cold start the jeep cranks but wont start. If i leave the key in the on position for approximately 5 minutes I can hear the fuel relay start clicking and than it will build pressure. I changed the fuel pump,pressure regulator and relay. I'm starting to suspect the pcm. Any ideas?:banghead:
