    Hi all, I bought a basket case ex oil field truck as a project and I need some help diagnosing it

    I Have persistent p0300 and random cyls and p0017

    I think the cats are plugged I am going to replace them

    I have replaced all the plugs all the coils all the plug wires. They were all trashed
    I replaced the throttle pedal the throttle body and the maf
    They were all bad
    Truck has 182k but there is written on the fender that it got a new motor at 134k

    Any help is appreciated!

    P0017 is a cam/crank correlation code. You may have a bad cam Phazer.

    Did you ever get it figured out?

    No I did not yet. I talked to a mechanic and his is positive that it is a stretched timing chain, phaser, or some sort of timing issue.
    I have too many projects at the moment. It will probably be a couple months before I can dig into it.
    I finally have a heated shop space so that is awesome.
    I replaced all the timing sensors and no change.

    Any test I can do with limited electronic equipment?

    Also the ps pump pulley is bent and the exhaust not being attached makes me think they might have replaced the 30k mile motor with a pos no idea.

    The other stupid thing I didn't realize when I bought it is that it is an SRW cab and chassis which means a std bed doesn't really fit due to frame width and length. Doh.

    You'd really need VMS with a VCMM (oscilloscope) or at least just IDS to look at PIDs. At idle, your VCT_ERR PID (Variable Camshaft Timing Error, deviation from expected) should hover around zero degrees. If it shows a consistent positive or negative number, your timing is off. The VCMM with VMS software has the ability to graph the CKP and CMP waveforms, which can then be compared to a "known good" to determine where the timing is. Without either of those, your best bet is probably to pull the timing cover and check the timing manually. If you need the Workshop procedures, let me know and I will get them over to you.

    Almost sounds like a salvage yard engine, they tend to do a number on them when they extract them with a claw.

    Yep...unfortunately, chassis cabs use a different frame than pickups. Chassis cabs are referred to as "Narrow Frame" while Pickups are considered "Wide Frame". Therefore, pickup beds will not align with a chassis cab.

    Anything you can supply is greatly appreciated!

    Is there any way to determine if the engine is a replacement?

    If you PM me your engine serial number and VIN I can see if they match what is in the database.

    Awesome thanks! I will do that.
    I got layed off and I have too many irons in the fire at the moment but I have it torn down to the point of pulling the valve covers and timing cover when I get ready.
