I replaced the fuel pump on a 2002 Isuzu Rodeo, V6 it started after I primed the fuel rail, the vehicle started up now it will turn over but won’t start, fuses check good, fuel pump comes on and vehicle has spark. Battery is new. What could cause it from cranking all the way over? been told the fuel pressure regulator could went out what do others think.

Hi Probably i know the answer to this. Probably a fuel line leakor the relay doesnt work (the fuel pump relay switch)And have you check the fuel pressure in the fuel line when the fuel pump is running?Hope this helps!
