I have a 99 F250 super duty 7.3. Millage is about 111,000. The truck set for almost 2 years because of a rotten oil pan. After I replaced the oil pan I changed out the fuel filter. I took out the old fuel and put fresh in.

The truck has no power. Feels like the brakes are on. Top speed 45-50 mph. In park the truck revs up slow also. When I drove about 5 miles the engine would start surging and looping very bad. I replaced the ICP sensor and that fixed that but still no power.

I have a Actron cp9145 Auto Scanner and it's not picking up any codes. When I put it in real time data mode all check points say n/a. The scanner has been used on the truck before and still works fine on other vehicles. The fuse to the pcm is good ( #30 ) I have checked all the harness and haven't found any problems. I can't get a data signal form the pcm. Could that be where all my problems are coming from? I have done the power and ground check on the plug and its OK.

Thank you to any body that can help

 

Truck will not run if the PCM is bad... Look at a plugged pick up. Check fuel pressure at idle and when driving, I bet you find your issue.

 

Where do I hook up to do a fuel pressure check ? Is there a check point some where?

 

Truck fixed. Inter cooler tube slipped of on passengers side. Was not easy to see from top because it was under the battery. I found it while looking for a place to take a fuel pressure reading.

Thanks
