Is stallcondition repeatable Can dealer reproduce?
WaterSeparator / Filter Does the Water Separator / Filter have water in it andwhat is the amount?
Is thegovernor assembly free to operate? Inspect pedal and cables for properoperation and no signs of significant wear or binding

Turboboost pressure at torque converter stall(full load boost spec is 82 - 85 kPa)
CoolantTemperature (at torque converter stall based on gage reading)
Smokecolor during torque converter stall test (if any) Is the smoke Black, Blue,White or none visible
HydraulicPump Test and Adjust RENR3584 Check for correct system pressure and torquelimiter settings. (Note: this step may be skipped if the dealer can confirmthat the hydraulic system has not been tampered with ? factory settingsare intact.)
Test235-1790 switch for proper operation. Cold advance for FIP, switch openscircuit when the coolant temp reaches 37-43 deg. C and closes at 27-33deg C.
"Wiggle"check electrical connections to and from FIP shutoff solenoid, cold startadvance, and electric lift pump circuit.

SpecificChecks/Tests required Response
Fueltank temperature during either stall condition.
Checkfuel connections, fittings and clips. Check for looseness or fuel leakage.
Lowpressure fuel line interference conditions / restrictions (I.e. check routingof low pressure fuel line). Reference Service Magazine article on low pressurefuel system checks dated 23 Jun 2003.
Aeration(air present in fuel) See RENR2415 Test & Adjust. Air in Fuel ? Test(See illustration 1 for proper installation of clear tube on fuel injectionpump return line).
Fuelflow (low pressure fuel system) See RENR2415 Test & Adjust. Fuel SystemPressure- Test
Doesthe engine perform OK from a separate feed to the FIP? (Suspending a cleancontainer of clean fuel to gravity feed the FIP or fixing a slave liftpump directly to the FIP would eliminate the low pressure circuit on themachine)
