    Possible PATS problem?

    The whole reason for testing the input/output of the fuses was to confirm the basic operation without having to change parts. IF there's key on power in/out of fuse F2.2 and F2.8 THEN the CCRM is basically working. NOTE the "crank with no start" check list was included in the 2nd post (my...

    Plenty Fuel, No Spark. Car will not start

    From the diagram posted this should give a valid intake vaccuum reference. Hands down the best and easiest way is to "ask" the PCM what it "thinks" the Fuel pressure is. This then takes the total sensor and wiring into account. Many generic ODB2 scanners will have fuel pressure as an...

    Possible PATS problem?

    My wring diagrams indicates fuse F2.35 is only hot when the brake pedal is depressed. So your test results should be "odd" when the brake pedal isn't depressed. Did you use a test light to "load" the circuit or are you using a VOM meter? If using just a VOM meter that would also explain WHY...

    Engine Knocking nosie after replaced upper intake manifold

    Confirm that the part replaced is actually the lower intake manifold (the plastic part that bolts directly to the heads). Was any other work done at the same time? Valve covers off? When the work was done was there any coolant spilled when the old intake came off? Can you post a video of the...

    Plenty Fuel, No Spark. Car will not start

    True. For the 1999-2004 MY a faulty FRPS value would cause a crank with no start. IMO you should FOCUS here. IMO your problem is NOT a missing vacuum line to the FRPS. Why? Because every motor before it starts has zero vacuum. The intake vacuum reference line comes into play once the motor...

    Disable parking brake for convertible top

    There's a switch in the e-brake handle that creates a GROUND when the e-brake is applied. Find this wire and connect it to a full time ground.

    Swap

    yes. The wiring harness needs to match what the PCM and body wiring harness is expecting. Do you realize that this will be removing a PI motor to replace it with a non-PI motor? It seems that you will get a better result if you were to use a Romeo out of a 2003+ model year.

    4.6 swap

    Wow. A 2001 Mustang GT with a Windsor block. Has this car had a previous motor swap? It might be helpful to measure the diameter of the torque converter bolt holes for the torque converter itself and for the 8 bolt flex plate. My research indicates there may be 12" and 11.5" torque...

    2000 GT Strong exhaust smell possibly really rich but no codes

    There really are a ton of "possible" items that could cause a rich condition. One that also comes to mind is an exhaust leak. But instead of replacing parts consider testing more. Do you know if: the O2 sensors are switching rich and lean? what are LTFT and STFT doing. is fuel pressure...

    Possible PATS problem?

    Please review the crank with no start check list. The cluster displaying all dashes is a dead giveaway that: The PCM is NOT being powered up. Either no power or no ground. The PCM is dead/bad This is not a PATS problem. The Blinking theft light is a SYMPTOM of the problem. Review the part...

    Missing coolant sensor 4.6 2v

    The later model year Panthers do not use an ECT sensor. Instead they use a CHT sensor. Therefore there's no reason for Ford to build up the boss on the casting nor to drill and tap the boss. There is some risk that If you were to drill and tap a hole where there's not the thickness of a boss...

    Possible PATS problem?

    Turn the key on but do NOT crank. Does the check engine light come on? Does the theft light come on and then go off after a 3 second "prove out"? Does the cluster display the mileage at initial key on. Does the check engine light go out when the motor is cranked? 1996+ Crank with no start...

    PCM Going out?

    No. Any replacement PCM would be a re-man'ed unit. Just wondering. Has the tune been loaded via a "plug in" chip? I would be concerned if this is a chip tune. Does the car drive mostly OK? How about before the modifications were done? If so I don't think it's likely that the PCM is "going...

    Hi guys i just got a 2003 mustang gt 4.6 how do check kow it the car has pi heads

    Your 2003 GT has PI heads unless someone has swapped in a non-PI motor. It may have a Dorman PI intake. The part numbers on the plastic the bolts that hold the COP into the intake go DIRECTLY into the plastic and resemble wood screws. A real Ford unit will have brass inserts and real...

    2000 GT Strong exhaust smell possibly really rich but no codes

    Let me ask you. What color injectors originally came with your 2000 GT? In my 2000 GT the injectors are YELLOW. To me it's not a surprise that your 2000 GT is running rich when larger injectors that what the PCM is expecting have been used without a tune. While it's true that a 2000 PCM...

    help! fuel problem?

    There is a big difference between an ODB2 scanner and a code reader. The reader is used to read DTC codes. A scanner is used to access operational PID's. Further not all scanners are created equal. Some will only access ODB2 generic PID's. Do your homework. Maybe if you live in a small area...

    help! fuel problem?

    IMO it seems likely to me that your problem is a weak fuel pump or a leak in the flexible lines inside the gas tank. Do you want to know for sure? Do you have an ODB2 scanner? If the problem is a fuel delivery problem then it will show up in the operational PID's. Short Term fuel trim Long...

    Will these Explorer injectors work on my 01?

    What happened to the original injectors? Are you planing to re-tune after swapping? You are aware that you can't swap injector size without updating the tune.

    Need help..ASAP!

    WHICH fuse? F2.13, F2.18, F2.33, or F2.41? It does make a difference in the trouble shooting. 1999-2004 MY fuse panel schedule: https://www.allfordmustangs.com/forums/4-6l-tech/305933-1999-mustang-gt-2001-motor-swap-wont-fire-please-help.html#post2669271

    Drivetrain Transmission Swap.....

    You know it does make a difference which model year car you are tying to swap this into. Very different speed sensors in a 1996-1998 (VSS) verses 1999-2004 (OSS). Note, a T-45 comes with a VSS sensor as well as a OSS sensor. Are you expecting a "plug and play" swap? What are you trying to...
