Hi everyone I'm having issues with my 2000 Gmc Topkick with 3126 cat 8YL. Shuts off while driving sometimes go into idel other times you have to restart the engine. It will idel and high idel all day long. Till you start driving. I only owned this truck for 2 months when I bought it. It started doing this. Previous owner changed the steering column. Not sure why. I cleaned the fuel tank. blew out all the fuel lines replaced fuel filters.new heui system,ipr,icp fuel pressure regulator, Throttle positioning sensor. I pulled all the injectors. O rings look good. Getting 72 psi of fuel pressure. I'm stumped not sure what I'm missing.im not able to get a check engine light and im unable to me the obd2 to work. Could someone please help. To figure out why this engine is doing this.
Thank you..

'I listed a surplus Watermota diesel on DieselEngineTrader. It took a few months to sell, but I was delighted as the engine was quite obscure and I never thought anyone would buy it!'

'I had hundreds of "hits" on your website which generated 5 or 6 inquiries from all over the world; Germany, The Philippines, Korea, Sweden, and Spain. I sold all 3 of my engines to a buyer from South Korea. Your website was invaluable to me in selling these engines; no other ads that I ran produced any inquiries.'
