Have Truck Repair Questions? Ask an Expert
Hi Randy, My name is***** is the make and model engine and any fault codes if the check engine light is on?
Hi Randy, Sorry for the delay. I help on here in between jobs as time allows. I was logging out for the night and heading to bed when you replied back. I have a repair business and 7:00 AM comes early. No throttle response could be a number of things. Cat ET connected will help troubleshoot this. Could be a faulty throttle position sensor, cam sensor problem (usually will cause a no start condition), ECM software or wiring harness issue, Injector problems. Without codes you will need to verify fuel pressure with a gauge and if fuel pressure is good you will then check the other items I mentioned. Let me know
Randy, im glad you are getting it worked on. Experts on here are not employees of the site and we only get paid a percentage of the question value on positive feedback or accepted answers. Until either happens our time is voluntary. We can opt out and the question goes back on a board. There is no guarantee that someone that can help will be logged in after midnight but is possible. This is not something that can be accurately diagnosed on the side of the road without a scan tool unless you have really deep pockets to replace everything including and ECM to guess and throw parts at it since there are no codes or possible no codes. Could be a power loss to the ECM. Do you keep a scan tool in the truck with you that will read live data?
Have them drop the oil pan and remove a couple rod and main bearing caps to inspect
Also check for signs of coolant in the oil pain and do a cooling system pressure test to see if you may have a liner problem, etc.
If inspecting from below.... Rods and mains look okay and the cylinder liner walls are not scuffed or scored and there is no coolant in the oil it would be another problem for your no start but if any of these are found then yes you will need a rebuild.
Thanks for the update. keep me posted on the final diagnosis....
