hi having trouble with hard start when warm, long extended crank will usually start, aways starts right up on cold start, some times will crank 30 seconds when warm any help app., also has codes 1693 cant seem to get other codes, key truick does not work on 98.5, i have snapon brick, and otc scan tool. has fuel pressure gauge, lift pump seems to working ok, thanks dale, also would like to add that injection pump was replaced with cardone reman pump, about 6 months ago, but only has about 2000 miles on it,

P1693 code means there is another code present... So your going to need to keep trying to get the other code to present itsself. As for fuel pressure what is your ilde pressure and WOT pressure?

There is a overflow valve on the vp maybe you have a bad one? there cheap and easy to replace.You may have a bad pump.I just had a bad pump.Mine was junk and it was a fresh rebuild.They sent me another but it still was a drag.I hate to bad mouth places so i wont,But i know a place i will never give my money to any more.
