Ok looking through threads with a similar subject I know to check the rubber feed or return lines at the rear of the block. However this problem just arose after I had the A/C compressor replaced at Midas. Now the two idiot lights that use to light for 30 sec do not come on. Check Engine and Trans Temp???? no longer come on. If the truck sits overnight it will not start without giving it some throttle. It will start, run rough then settle down. Will continue to start without issues until it sits overnight again. Any guess?

Thanks

I would check the wiring connections under the hood. Sounds like something got pulled while they were working on it. Unhook them and plug them back together. Good luck and I hope this helps ya.

Alrighty guys, anyone have a picture of the feed or return lines at the rear of the block? Are the “feed and return” lines the same as the Lift Pump lines?

Any help is appreciated.

In red is the return hose.
The intake hose will be found right by the return hose near the temp sensor

Thank you for the information!

Is your intake grid heater cycling? Sounds like the same symptoms as one not heating on pre-start. Mabee it got unpluged somehow? Might be worth checking.

Just like to thank you for the reply's and update what I found to be the problem. The gasket on the Fuel filter/ water seperator had spun on the filter thus allowing a very slow air leak. The water in fuel senor on the bottom of the filter failed hence no idiot light upon start up. New filter, new sensor and the problem has been gone for 1 week now. No issues. Thanks again.
