First I would like to start by saying I think diesel bombers has the most diesel intelligent members any where . have read numerous post and u guys seem to pool all the knowledge to solve problems and to improve any ones diesel experience . hi I am bg fordman . I have a 2002 f-250 7.3 auto 4x4 extended cad short bed . truck is bone stock . I purchased truck a couple of month's ago from the original owner . this is my third stroke and have gotten great service out of them . I was able to purchase it for what I feel was a good price giving its issues . with that said . the truck runs smooth no jerking or loping . but has zero power . he said dtc showed p1209 code which I believe is injector control peak pressure change test fault . another code p0381 and a po562 . the codes were cleared when I purchased it . the truck cranks several times before it will start . there is no check engine after start . if u try to drive which is almost impossible giving its lack of power . check engine light will come on about the time the truck shift's from low to second gear . and when light is on scanner says zero codes . light will stay on until u turn the truck off . at next start the dtl light will be off . I have replaced the ipc and ipc connector because there was oil in it . I replaced fuel filter . put one new battery . I unhooked fuel line from fuel pump that pulls from the tank . I put a clear hose in a jug with a filter to iliminate possible pick up issues from blocked sending pick up . I ceaned fuel pressure regulator and lightly stretched spring . I don't have a liquid pressure gauge so was unable to test fuel pressure . but when I turn the ignition on the pump starts pumping . my question is the pump appears to have enough pressure to fill fuel bowl with enough pressure to open pressure relief return valve . the pump times out after a few seconds with the key on . but if the pump ran continuous with key on it would drain a five gallon jug of fuel in about 5 minutes . any help would be greatly appreciated

 

Are you getting any smoke under load, like when you are trying to make it uphill? Low power and extra smoke typically means you have a boost or exhaust leak somewhere. If you have low power and no smoke, then you could have an electrical problem, which could be related to the po562 code, indicating a weak alternator, or possibly air in your fuel, but you probably would have noticed that using the clear tube, though the air leak could be post fuel pump.

Check the air filter for restriction and turbo compressor wheel for dusting.

If you have any extra smoke, and you are certain that you don't have a boost leak, then check behind the turbo and look at the up-pipes (especially at the collector). If you see soot, then you have an exhaust leak.

 

no not getting any smoke at all . the truck is hard pressed to pull out of its own tracks . have replaced one battery the other one I,m not real sure how good it is . when idling it funs smooth no miss firing or erratic . would low voltage cause such symptoms . I did see some air bubbles in the clear fuel hose . was not constant but they were some .

 

Low voltage can cause a lot of issues. Voltage when running should be 13.8-14.2, when the GPR cycles off. If it is lesss than that, it is not necessarily the alternator, there could be a short, or excess current draw somewhere. Also any air in your fuel, is not good. You could try cranking it for a few seconds, then let the starter cool down before cranking on it again. Doing this a few times should bleed the air out of the high pressure oil lines. Air between the fuel tank and fuel filter will bleed off just by cycling the key a few times.

 

Have cycled the ignition several times to help purge system . Would low voltage cause a p 1209 code ? Is it possible that a bad ipr could create these symptoms .

 

Yes, a bad IPR could cause these symptoms.
A quick and easy check is to see that the tin nut on the back of the IPR is not loose and the wiring / connectors look okay.
Another is to check that oil is an 1" or less below the top of the HPOP reservoir.

P1209 indicates that injection control pressure was above or below desired level under normal driving conditions.
Possible causes:
incorrect oil or viscosity
poor oil quality
gel fuel/no fuel
low fuel pressure
damaged IPR valve
high-pressure oil system leak
damaged high-pressure oil pump
damaged PCM
Verify correct oil quality/viscosity and correct fuel grade are being used for the temperature conditions.

 

I am still at a loss with this . have replaced icp and connector . replaced fuel pressure regulator . checked fuel pressure it was 64 pounds . replaced both batteries. pulled inter cooler hoses to inspect . they were pretty clean all and all . there was a light bit of oil but very little. hpop is full . this was a gradual thing . from time it was noticeable to where it was unsafe to drive approximately 2 months . now it doesent start at all . any help would be appreciated .

also when it was running there was no smoke .

 

Ok I finally got to pull dtc . there is a P0381 P0562 P1209 P1211 P1212 P1280 P1670 . Now can anyone make sense of this mess . Is it possible that some of these issues could be a bad body ground ?

 

hey guys any help would be greatly be appreciated . have a no start situation . I just replaced icp and connector . new batteries . new fuel pressure regulator . fuel pressure is 65 pounds. cleaned all body grounds . replaced main positive wire that feeds power to the cab. all new relays in fuse box . have checked all fuses and they test good . hpop is full tested gpr it tested good . voltage seems good . it turns over great . just wont fire up . can give a small shot of starting fluid and it fires up and runs for seconds . I don't use much because I personally don't care for using it . but out of frustration I did. any ideas as to what im missing ?
