97 7.3L Runs but cuts out when warmed up.

jaybo20 · #1 (**permalink**) 09-15-2008, 06:33 AM

I have a 97 7.3L Diesel 3.4 Ton P/U. Starts fine, last week replaced fuel filter. I can drive the truck for a good 30 minutes. Everything is fine, good power, no troubles. Then it will start to miss and kick out. I have trouble giving any pedal to it at all. I can stop and it will idle fine. Start up again and same problem. If I let it cool down. It will be good for another 20 minutes running fine. Is the problem in the fuel pump or possibly the High Output Oil Pump? I am fit to be tied!!!

When was your last oil change? If your oil gets old and thinned out, it came mess with your injection pressure. Or maybe check out your ipr.

I changed out the Camshaft Position Sensor last night, I will test the vehicle today. The oil and filter are new. I have also replaced the Vaccum pump and Fuel Pump. I am hoping this will be all that is wrong with this truck. Thanks for your imput.

it is a possibilty but not always the case inwhich some people think so, i dont tell people to buy parts unless diag has been done , hopefully that will take care of it but always run diag before throwing parts at it
