Check the vehicle voltage while cranking. If it's below 10 volts then it will crank but the injectors won't fire.

Welcome to FTE.

 

hi all
ford just checked the codes again it has codes
IPR P1282
FUEL COMMAND P1663
AND WE CAN NOT CLEAR CODES
ANY IDEAS
THANKS

 

Cannot clear codes? That doesn't sound right.

From the manual

P1282 a b Excessive ICP
KE5 DIAGNOSTIC TROUBLE CODE (DTC) P1282
DTC P1282 indicates excessive injection control pressure was detected during continuous diagnostic monitoring.
Possible causes:
intermittent IPR control circuit short to ground

Yes INSTALL a new IPR. RESTORE system. CLEAR DTCs and RETEST.
No GO to KE6 .

KE6 CHECK FOR INTERMITTENT SHORT TO GROUND
Install breakout box; leave the PCM disconnected.
Measure resistance between PCM test pin 83 and ground.
Wiggle IPR circuit connectors and wires to attempt to induce short to ground.

Is the resistance less than 5 ohms?
Yes GO to KF6 .

No REPAIR open in circuit 821 (BR/OG). RESTORE system. CLEAR DTCs and RETEST.

KF5 CHECK FDCS CIRCUIT 821 (BR/OG) FOR SHORT TO POWER
PCM disconnected.
Key on, engine off.
Measure voltage on circuit 821 (BR/OG) between PCM test pin 95 and ground pins 25, 51, 77, 91 and 103.
Is voltage present?
Yes REPAIR short to power on circuit 821 (BR/OG).

No GO to KF7 .

KF6 CHECK FDCS CIRCUIT 821 (BR/OG) FOR SHORT TO GROUND
Key off.
Measure resistance between PCM test pin 95 and ground pins 25, 51, 77, 91 and 103.
Is the resistance greater than 10,000 ohms?
Yes GO to KF7 .

No REPAIR short to ground on circuit 821 (BR/OG). RESTORE system. CLEAR DTCs and RETEST.

KF7 CHECK PCM OUTPUT STATE FUNCTION
Key off.
Connect PCM to breakout box.
Perform KOEO Output State Test.
Measure voltage between PCM test pin 95 and ground pins 25, 51, 77, 91 and 103 while pressing and releasing accelerator pedal.
Did the output toggle from 0.5 ± 0.1 V to 0 V?
Yes INSTALL a new IDM. RESTORE vehicle. CLEAR DTCs and RETEST.

No INSTALL a new PCM. RESTORE vehicle. CLEAR DTCs and RETEST.


Now that we've covered the book answers, and if you haven't dozed off from trying to read that, I'll throw in some additional advice. Since we know your injectors are not firing, I'd inspect closely for a short to ground or chaffed wries around the wiring going to the IPR, ICP sensor, and above and behind the 42 pin connector. The 42 pin connector is the square box with a bolt in the middle of it that looks like it's attached to the valve cover under the air intake tube between the filter and the turbo. (our driver side your passenger side). Also try unplugging the ICP sensor and see if it starts that way.

Next you can ohm the connections between the IDM and the injectors to check for any shorts. Be sure to wiggle the harness while checking to help find any intermittent shorts. This link will help with the pin outs on the harness connectors. http://www.gbreman.com/docs/techbull...eplacement.pdf

 

is it very common to replace a hpop? and would it bring up code for the ipr as iv been told to replace the hpop thanks

 

I would ask Ford if they will put your old HPOP back in free of charge if it is not the problem.
Before I replaced anything I would follow Chris's steps (at the bottom of he's post) . Your ICP monitors pressure at the injector and feeds that info to the PCM which sends commands to the IPR to regulate the oil flow to the injector. If any of the two are faulty (which is common) the above wont happen.

Post #8 has pictures of your ICP and IPR. Try unplugging the ICP and see if it starts. Is there any oil inside the ICP plug which would indicate a faulty sensor.

mate i have checked every thing he has suggested im at a loss

 

P1282 is excessive pressure. Either the IPR is sticking or there is a short to ground. So ya HPOP is supplying pressure. Do they have a IPR they could try ?? All the wires are good hey ??

 

I really think you need to swap in a good ipr and see what happens.

 

Could be something as easy as a failed CPS. Like it's been mentioned, oil isn't spurting out the injectors because the injectors are not trying to fire. Most common cause of a no-start is a failed CPS. Surprised it hasn't been brought up yet. You can crank and crank, and oil pressure will continue to rise, but those injectors will never even attempt to fire unless that CPS is providing a signal.

 

If Ford dont have the diagnostic software to read RPM,ICP pressure while cranking they are pissn in the wind. 9 times out of 10 a no start issue will be a sensor.Without software, First try CPS then IPR then ICP. (good call Curtis)

 

ok so update today i replaced the cps,ipr and icp and still no go should i just burn it? will it start with hard codes in pcm or do they have to be cleared ? thanks

 

Have you checked the hpop res. to see if it's full of oil? Other than what you've checked it sounds like you really need a scan tool to measure actual icp.

I had a similar no start issue and my pump was only making 200psi, thought it was a stuck ipr, changed it and still no start. Installed a new pump and there you go she was up and running. Not saying it's your hpop but you need to verify it's making pressure. You can even have a hydraulic store mock up a hose and a gauge to see what kind of pressure you making while cranking.

 

Thanks do you know what it should make when it's cranking

 

Takes 500psi to start. If your getting more than that it may be something else and not the hpop. If it's making less than that it is probly the pump.

 

Did you ever confirm that your voltage is ok? Must remain above 10 volts while cranking...
