Possible bad transfer pump...P1693 doesn't tell me anything other then code is stored in the PCM... You need to pull code from ECM if there is one stored.

sometimes it starts and it runs for a minute or two then starts too miss and jerk and die may start back may not, last year we had to replace the crank sensor so we replaced it again this week that was't it

roadrage I would check the fuel volume from pump if you don't have a gauge. Replace fuel filter before test if it is not new... Disconnect fuel line at injection pump and run a piece of hose into a container. Bump starter, fuel pump will run...measure fuel in container ....should be 45oz min if below that you have transfer pump bad. Might need to do test several times to get accurate test result.
