    You probably don't want to hear this but get it running again and take it to a good mechanic and have it diagnosed, you don't want to throw parts at it again, cause as you know that can get expensive real quick and still not have it fixed.

    I worked it today for about 5 hrs. It took about 10 seconds to start, but it ran fine the whole time. I carried about 90 tons of 304 gravel out of a quarry to a location and it pulled fine. Was sweet relief!
     
    xsetra, baha, austinmike and 5 others Thank this.

    Went to work today and as I took off pressure fell on its face when I pushed the pedal hard, would come back up to a decent PSI when I let off. Called and missed job, I avoided freeways back to CAT. Dropping it off now

    Here’s while going up the road. The longer I kept my foot down, the lower it would go. I barely pushed the pedal the 15 miles it took to get to CAT until I got about 1 mile away. Started flooring it and was seemed to be normal again.

    Could it be the throttle position sensor ?

    I dunno man….it’s strange. The fact that it takes so long to start every morning is an indicator that something is still wrong. No issues yesterday with fuel pressure.
     
    Rideandrepair, Siinman and lwlevens Thank this.
