CAUTION: To prevent equipment
• Do not leave the IPR valve energized longer than 120 seconds at a time.
• Inspect adapter o-rings before performing these tests. Replaceo-rings if worn, cracked, or cut.
1. Verify base engine oil pressure.
2. Turn the vehicle's ignition to Key ON, Engine OFF.
3. Usea diagnostic tool(OTCNo.6764or equivalent) t o closethe Injection PressureRegulator ( IPR)valve.
4. Apply shop-air pressureof at least 100 psi (689 kPa) to the high pressureoil system:
2003 —2004-1/2 Vehicles: Use adapter No. 551581; remove valve cover to access high pressure oil port.
2004-1/2 —2007 Vehicles: Use adapter No, 511671; use the Injection Control Pressure (ICP) location.
Note: It may be possible to use adapter No. 511671on 2008—newer6.0L Econoline vans.
5. Usea diagnostictool (OTCNo. 6764or equivalent)to openthe IPRvalveand allowthe Oilto drain.An

• If no changeis heard,the IPRvalvemaynotbefunctioningas commanded. I nstalla newIPRvalveand
repeat the test.
• If the no-start condition exists, an audible leak may be identified by using a mechanic's stethoscope (OTC
No. 4491 or equivalent)through the oil fill tube or left valve cover crankcasevent hole.
