Hello???....still with me Dan?it's been near an hour and a half and no response yet...I guess I need to change the urgency to high...I'm sitting at the bottom of an exit ramp and was hoping I'd get a fast response..anything you can suggest will help

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

Hey Dan..I understand that 7 am comes early and the all that..it would have been nice if you would have at least let me know that you were going to be done for the night...I'm at a service shop now and they are looking into it after being towed here..I wish you would have sent the case to another tech b4 going home..needless to say after 11 hours of waiting on an answer to your questions I had to do something ...sorry to say I'm not happy with the purchase of this tech forum

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?

Ok..no Dan I don't carry a scan tool in truck..the shop I'm at seems to think it cooked the bottom end and needs a motor or rebuild..

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.

Ok...I'm home ...now I used my mom's PayPal account to pay for this just answers line..she feels the same as I do about this site...after my 4th post..once I got to the service place b4 I heard from you the next day at 1055 am on the 25th it was out of my hands so the usefulness which would have helped the night b4 was wasted and every thing you suggested after I got there was out of my hands she told me to post this...We are done talking, I needed assistance and paid for it, you failed and I have case in paypal for refund.
