Hello X.XXXXXXXXXXXXXXX, did the engine run before you pulled the pump? Which o-rings did you replace?

ya it ran perfect except for the leak n i replaced the o- rings on the lines, im thinking it might be electrical or maybe it aint getting feul?

Info Request

You did not relace the o-ring on the plug under the bottom side of the pump did you? You double checked that you pluged in the injector pressure regulator on the lower side of the pump?

no i did not replace that o-ring the only reason i even replaced the other ones is because ford told me they were leaking but they werent at all. ya i made sure the ipr is plugged in

how long in seconds would you say you have cranked the engine, Have you checked for power out at the glow plug relay when you turn the key to the run position?

im not sure how long ive tried a few times and turned it over for quit a while and the glow plugs work, but theres no smoke or anything when turing it over if that helps

When you had the fittings off of the pump did you make sure the check vavle and spring under the fittings did not come out? remove the connector on the icp sensor (located at an angle on the front of the drivers side cylinder head) try to start, this will give the pcm a default icp reading of 750 psi, if it still does not start I want you to remove the icp sensor and have an assistant crank the engine while you watch for oil to come out of the hole, have them be ready to stop cranking, as it will not blow out with great force, but it will come out fast enough to make a huge mess. Let me know if no oil comes out while cranking

ya we already did but did not not crank it too long, and it did not start

Info Request

when the oil did come out of the hole, was it a strong waterfall, or a small drip?

it was comin pretty good but it wasnt squrting way out either

Posted by SuperBob 125 days and 8 hours ago.

Info Request

That is good as this is a high pressure low flow system, did you disconnect anything but the IPR? Also is the tachometer registering any rpm during cranking?

Reply

no thats the only thing that i disconnected and the tach moves a little i also noticed that there was a camshaft circut intermittant error again and i just put in a new sensor

Posted by SuperBob 125 days and 8 hours ago.

Info Request

did you put the sensor on at the same time as the hpop seals? Is the engine speed cranking over at a normal speed? Low batteries will not enable the injectors, maybe try a battery charger for a while and see what happens.

no i did not change the sensor, i did not think i needed to as it ran good before, and the battery isnt to low ive started it on less power but i did just put the charger on it

is there a possibility it isnt gettin feul or somthing, there is fuel in the filter and i took the lines off the bowl and there was fuel there to, but there is no smoke when turning over

 

Posted by SuperBob 125 days and 7 hours ago.

Info Request

High pressure oil is what pushes the fuel through the injectors, so yes it is possible that not enough oil pressure is building to get the pressure through. When I had you pull the icp to see if oil was coming out is about the only test you can do at home without a ford scan tool to see if oil is getting to the oil rail. We really need to see what the actual pressure is to confirm it has enough oil pressure. How about the springs and check valves under the fittings that you replaced to o-rings on, did any thing fall out while you had the fittings off? Also you can check the fuel pump ability to get fuel to the engine by removing the filter again and drain the fuel bowl with the drain valve on the back of the bowl. Close the valve and have an assistant turn the key on to see how fast the bowl fills up, should take less than 5 seconds.

no nothing fell out of the pump, is the bowl supposed to be filled all the way to the top or like an inch or two over the bottom cause all it got to was about an inch or so deep to the bottom

Info Request

Sorry for the delayed response, i have a long ride to get home from work, if you cycle the key a second time it should get real close to the top real fast. Are you sure there is fuel in the tank?

ya the tank is full n i got the bowl filled up.

Posted by SuperBob 125 days and 5 hours ago.

Info Request

Well I've got only one more suggestion for you, make sure the batteries have as much charge in them as you can get, cycle the key to the run position for 30 second and crank the engine for a solid 30 seconds to get out any air that may be trapped in the high pressure oil system. If this does not get it going you just may have to get her towed to a shop, as without certain scan tool capabilites we are really limited in how far we can go through the net.

ya i suppose thats about what i was thinking to. thank you for your help, i really appreicaited it

I am not going to hit the answer key, as I could not get you to the cause. If you do find out that it was something that I said, then come back and let us know.

well i just tried that and it didnt work i also got two codes , ICP voltage nat at expected level code and an exhust back pressure sensor circut malfuntion code. what do these mean

 

Posted by SuperBob 125 days and 3 hours ago.

Info Request

The ICP code was probably set when we tried to crank the engine with the sensor disconnected, the exhaust back pressure sensor is just forward of the hpop reservoir, it is a three wire sensor, leaving it un hooked would not cause a no start, but an internal short in the sensor would cause a not start, try to unplug it and try to start, you may have pinched the wire or something during the repair. otherwise it may just be a bogus code set from extended cranking and lowering battery voltage.
