SOURCE: oil pressure gage

At idle, at operating temp is there any ticking from top end of engine? Are there any knocking noises brom bottom end?
If no noises, change oil and add some Marvel oil to clean out galleys. If that dosent work, change oil pressure sendingf unit. Also, if you have a mechanical oil pressure gauge, hook it up and take a direct reading. Oil pressure (in any vehicle) at idle should NEVER be less than 15psi. Generally in 4.0 jeep engines it's never less than 30, with a high reading at driving rpm of about 40-60! (but, you did not mention what engine you have)

SOURCE: 97 gmc pickup, 5.7 eng, fuel pump not operating,

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.

SOURCE: Fuel pressure intermittently drops causing sputter and die.

check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

SOURCE: 2003 f 350 starts then shuts down 2 or 3 times in

The first thing i would check is the Glow Plug Relay. Depending on your engine 7.3 i think you have, there should be (2 solenoids, or just one) sitting on the top front a little to the right of center. (right bank of engine that is) If you have 2 of them one should be smaller and it is the one furthest to the rear of the engine. It controls power to your glow plugs for cold start up. When you turn the key to the on position the 2 larger wires should both have power. When the ignition is off only one wire should have power. Check this if you do both these tests and only one wire has power with key on or off then you need to make sure that the key switch is sending power to the solenoid. Do this by checking the smaller wire with key off. It should not have power and then with key on it should have power. If this is good and test one is bad then the relay is bad. Note This is not true for the larger realy that sits furthest foward on the engine. The bigger one. This test will not work for it but it controls your intake heater. On another note: This is a timed circut and will "kick out" after about 1-2 minutes. In otherwords it does not stay on all the time that key switch is on it will for for about 1-2 minutes then shut off! Next would be your injectors are getting weak or bad and even your HPOP could be getting weak. or glow plugs in engine are out, In otherwords there are alot of possibilities causing your problems If you are getting a misfire code for your injectors then you may have some weak or inop injectors. Any way this will give you a pretty easy test for the most common failure which is the Glow plug relay. About 35-40 bucks at your local auto parts house.

Sometimes when a fuel filter is stopped up,and you change it,the fuel pump later,will go out,cause of the strain on the pump.

How much injector oil pressure should I have with just starter spinning over no crank and pours white smoke out exhaust


Here's you some info from a ford manual.
you can use any scan tool that will rear ICP pressure and RPM. you need at least 100 RPM while cranking.

Check oil level and quality first. if its low, it may not start, if it's old it may aerate easily(mix with air easily)

If the smoke is white/gray and smells like raw diesel, you possibly have a stuck open/Leaking Injector, Leaking injector O-Ring Seal. A failed glow plug system, can make white smoke as I am unsure of the cranking temp. if it is Blue/White there may be a compression ring issue.

A note on 7.3L injectors!!!! ALL of the Injectors are the same EXCEPT #8 (Last one on the Driver's side) It is a "Cackle" Injector. It looks the same but is slightly different. It even has a different part number in our Ford Catalog.

I hope that helps you let me know if you need anymore info.

Tools Required:
New Generation Star (NGS) Tester 007-00500 or equivalent

9c. Monitor ICP While Cranking (min 500 psi @100 RPM)
Purpose:
To determine if the injection control system can supply enough injection control pressure to sustain starting.
much-injector-oil-pressure-just-starter-ccu5ej1tcfbj3pe04s4es3xr-4-0.gif


Recommended Procedure:
Install NGS Tester. Access ICP and IPR PIDs on NGS Tester, and monitor PID readings while cranking the engine.
Note: CMP signal is required before IPR is commanded above 14%.
If ICP does not meet the minimum specification of 3450 kPa (500 psi), the injectors will not be enabled by the PCM because of insufficient rail pressure.
If IPR goes above 14%, ICP pressure should easily go above 3.4 MPa (500 psi) provided that the oil reservoir is full, the IPR valve is not stuck open, the high pressure pump is building pressure and there is not an injection control pressure leak between the high pressure pump and all of the injectors.
Possible Causes:
  • Injection control pressure system leak
  • Oil reservoir level low
  • IPR failure (sticking open)
  • Faulty high pressure pump
  • Injector O-ring leaking

How long and easy is it to rebuild oil pump on 94 grand caravan 3.8l


Don't bother. Replace the unit.
3.0 liter
The oil pump assembly used on this engine is mounted at the front of the crankshaft. The oil pump also retains the crankshaft front oil seal.
  1. Remove the accessory drive belts.
  2. Remove the timing belt cover and timing belt. Refer to the timing belt removal and installation procedures in this section.
  3. Remove the crankshaft sprocket.
  4. Remove the oil pump mounting bolts (5), and remove oil pump assembly. Mark mounting bolts for proper installation during reassembly.

To install:
  1. Clean the oil pump and engine block gasket surfaces thoroughly.
  2. Position a new gasket on pump assembly and install on cylinder block. Make sure correct length bolts are in proper locations and tighten all bolts to 10 ft. lbs. (14 Nm).
  3. Install the crankshaft sprocket and timing belt. Recheck engine timing marks.
  4. Install the timing belt covers. For more details, refer to the timing belt cover installation procedures.
  5. Install the accessory drive belts.

  7. Check for correct engine oil pressure and for any oil leakage.
3.3 and 3.8 liter engines


  1. Disconnect the negative battery cable. Remove the dipstick.
  2. Raise the vehicle and support safely. Drain the oil and remove the oil pan.
  3. Remove the oil pickup.
  4. Remove the chain case cover.
  5. Disassemble the oil pump as required.

To install:
  1. Assemble the pump. Tighten the cover screws to 10 ft. lbs. (14 Nm).
  2. Prime the oil pump by filling the rotor cavity with fresh oil and turning the rotors until oil comes out the pressure port. Repeat a few times until no air bubbles are present.
  3. Install the chain case cover.
  4. Clean out the oil pickup or replace as required. Replace the oil pickup O-ring and install the pickup to the pump.
  5. Install the oil pan.
  6. Install the dipstick. Fill the engine with the proper amount of oil.
  7. Connect the negative battery cable and check the oil pressure. Check for any oil leaks.
for the 3.3 you can rebuild, 3.0 - replace.

1984 F150 302 Had oil pan gasket and both valve cover gaskets


you have several points to check!
the dip stick tube has a "O" ring seal at the bottom where it fits to tranny.
a reverse switch on tranny & the shifters selector shaft has a seal that may be leaking !
there are the cooler pipes from cooler to tranny [in & out] plus pump seal to the torque converter [leaks out between engine & tranny bellhousing] & then there are the drive shaft or shafts seals
so wipe it all clean & park it in a diffrent clean spot!
some will only leak when its runnung due to tranny,s internal pressure!

High pressure oil pump leak.


the high pressure pump provides the pressure to your injectors so the diesel luel can be injected at high pressure. You should fix this immediately. Call your dealer and ask for some help from Ford on the repair cost ahead of the repair. See what they will do.

I dont know where the oil pump is on my 89 toyota


On a 22RE the oil pump is on the timing cover behind the crank pulley/harmonic balancer,it has the crank timing pointer built onto it,generally they don't leak around the pump seal but as Monster80 pointed out they leak from the front main seal wich is installed on the front of the oil pump,pretty common for the 22R/RE to leak around the timing cover gaskets or out the bolt holes on the timing cover also,usually due to uneven tourqe on the bolts,to check the front main seal you need to look at the the crank from the underside right after you've shut the motor down,if the seals bad you'll see oil starting to form a drop on the backside of the pulley or the front of the oil pump housing.

WHERE IS THE IPR LOCATED ON THE ENGINE ?


The "IPR" is and Injector Pressure Regulator. It is a Solenoid used to control the oil pressure created by the High Pressure Oil Pump. The IPR is capable of regulating oil pressure from 0 to 5000 psi. On an 05 6.0l the IPR is located in rear, top, center of the engine in the High pressure oil pump. It can be identified by its gold color. It sticks out of the side of the pump pointing toward the driver side of the truck. It has a 2 wire plug that is held on by a metal clip. usually the ipr and plug are protected in a heat shield so you may not be able to see it right away. Some people mistake and IPR for and ICP. The ICP is a sensor that tells the PCM what the High oil pressure is. ICP stands for Injector Control Pressure. This sensor is located in the passenger side valve cover on and 04, 05 6.0l and in the top of the High pressure oil pump on an 03 6.0l.
