do you rebuild o2j's?

got it thanks

as far as swapping ecu's it has to be the same year is that correct?

thanks for that info but i'm curious you would do if it was your car? the engine timing is dead on the fuses are all good i've run a few electrical tests i've changed the fuel filter on my fass pump the IQ is set there's no fuel restriction i've got another pump i know that doesn't set off the...

hey i'm going to swap my ecm to see if that will correct my p0252 issue... what will i need to do? also will i need to get a ross tech cable

yes i have used the lockdown tools to set the static timing.... and yes i've let the car fully warm up i've taken it for a ride up an down the highway came back shut it off and restarted the car and the cel comes on again... that's what i thought the N108 controls the cold start advance

the 2 fuses are good i think they're 28 and 34 i'm so goddamm annoyed and the guys i got the pump from are just deflecting and saying its something else, they're suggesting that the crank is out of time with the cam, my buddy and i have set the IQ and the engine timing, the cel comes on maybe 10...

do you think it's plausible that the crank is out of sync with the cam causing this issue?

ohhhh i'm getting zero on the ip side and there's power to the plug going to the pump

i went out to double check and on the wiring harness side its reading .229 three times in a row

i'm at 88.1 on the lift sensor..... with that low reading on the ip connector should i be looking for a bad wire or possibly a bad ecu

i disconnected the battery but i'm not sure if i'm checking the right pins i'm touching the last 2 pins on the bottom row closest to the curved end and i'm getting a reading of 4.39 and i'm getting power to the #3 lift sensor but i'll have to double check the reading my probes keep slipping but...

i'm having this issue and i have a new pump on the car, what lift sensor are you referring to? the #3 injector lift sensor? i just had these injectors rebuilt with a new set of nozzles and are you saying pin 9 and 10 should have 12-20ohms each

i'm having this same issue p0252 !!!! i installed 2 new pumps and this code keeps popping up the engine timing and the IQ has been set

that sounds like you're referring to the IC hose?

i still haven't fixed this issue i'm annoyed as ****, i see the possibility of it being the N108 connection?

the engine timing was set prior to replacing the pump i did a cylinder head replacement and then received the pump installed it and got p0252 sent that pump back then they sent another pump i installed that pump made the IQ adjustment with my buddies snap on scanner and the code is still popping...

after i installed the second pump i had that 0216 i change the fuel filter and that went away but the 0252 popped up and doesnt want to go away

i wasn't trying to hold back any info, i've just done so much to this car and this scenario has been rather irritating to figure out i'm sure at the moment i was forgetting to add info, what's really eating at me is the fact that i've installed 2 pumps and they've both put out this code even...
