WJ Jeep cold start problems
 
Hi lads,
My JGC 4.7, 1998, but this is a new shape already.
I have the cold start problems, I have to hold the ignition key (I mean crank time) for 15-20 sec to get my engine on.
I have the P1282, P0443 error codes.
When I turn the ignition key I can hord that fuel pump is on for few sec. Sometimes I try to switch ignition on/off for few times, affter that no problems start the engine but not always.
Can somebody give my some idea how to solve this problem?
Thanks a million boys.

It could be the fuel filter/pressure regulator. It probably doesn't keep the pressure in the line after engine shutdown and the fuel flows back to the tank. Then during the next start the line has to be filled and that takes a little. There where some problems with an O-ring on the fuel pump, but not sure if that will give this same problem.
