MrX Posted April 11, 2011 Report Share Posted April 11, 2011 code p1345 is the dis. is out of time. code p341 is also the dis. is out of time. Ok lets start over find TDC. re stab the dis. after that on the scanner there is a place where you can rest the fuel trim and the cam and crank sensor. rest them before you start the car. After you rest let it idle for a while watch the fuel trim to see how much it goes up or down. then we will go from there. Link to comment Share on other sites More sharing options...
KISS_Racing Posted April 11, 2011 Report Share Posted April 11, 2011 Think he just restabbed dist. He couldn't get timing to come down... Now it is too low. Agree to reset and do start/idle... Link to comment Share on other sites More sharing options...
97car Posted April 11, 2011 Report Share Posted April 11, 2011 How many miles are on the timing chain? Sounds like what a neighbor went thru on a older vehicle and it would up being the chain was shot. Link to comment Share on other sites More sharing options...

Agree to reset and do start/idle... your right i restabbed it three times ..and have the same reading .or worst ..... i know i have had it right where it belong.s but nommater it wont get below 12 -..and if you move the distributor now it wont change ..the timeing has been on the low side from the beginning , it has not given me a 0 or positive yet .....thats why i restabbed nd restabbed .till my ribs couldnt take it anymore ........now for setting what both of you have mentioned ..im not that up to date with this tech two ..so not sure where to go with that ..or if i did know the readings .....ill take your call tonight when i get back on it ..if you would like to call .and guide me through this ........361..290..2096.......at this moment i have taken time off from it till tonight ..building a cage for my sons front runner ..so im on vacation ..lol ........ 97 ..its all new .........

JamesHigdon Posted April 11, 2011 Report Share Posted April 11, 2011 I have "been there" with these trucks. My daily driver is very nice, loaded '99 Yukon I bought from a customer becuase they lost patience with fiixing some issues it had. The passlock system was acting up in multiple locations and we could never get a bead on it. We finally replaced the ECM, used a Jet Dynamic Spectrum Tuner to go into the ECM and stop it from looking for the passlock module signal (because the module was bad as well) and now it starts and runs great everytime...besides a leaking pintle on the #8 injector I'm going to retrofit with a MPFI system. We have seen the igniter cause the issue you are seeing. If the igniter is malfunctioning the spark can be very intermittent and will occasionally (or always) act like the motor is out of time. You also have to remember the computers most basic function is to keep the car running, if it is seeing a timing signal it thinks is out of spec. then it will try and put the timing as close to spec. as it can go. You could also have just a straight up bad ECU, we have replaced numerous ECU’s over the past years in GM vehicles once all the trouble shooting lead back to the ECU and have never had it not solve the problem. We have found that always assuming everything can be bad on a level playing field tends to lead you in the right direction quicker then assuming one part is bad and another never goes bad and working it that way. If you’ve set the timing a dozen times and it’s still not right then look at something else! Link to comment Share on other sites More sharing options...
97car Posted April 12, 2011 Report Share Posted April 12, 2011 I helped with a 98 pick up with the 350 in it and tried chasing the timing and in the manual it said it had to be set at the dealer on the computer. We had it running but not satisfactorly, he took it to the dealer and I guess they flashed toe computer and set the timing. 7 years later everything else on the truck has had to be rebuilt since then.

MrX Posted April 12, 2011 Report Share Posted April 12, 2011 Ck. the harmonic balancer is if it has spun that would put the crank sensor out of time. Make shure the no. 1 piston is a TDC. I seen the keyway brake. Link to comment Share on other sites More sharing options...

Mark knucklehead before me changed the dist .... so out with the wind on that ..he didnt mark it ....i can get the dist to line up with the mark .with cap just aboult where it should be give or take a tweak ... ..but that rotor tang is wide you know ..i read aslong as the tang is lined up with the dist pointer number 8 which on this dist points towards number 1 bank... .it should be good .bank 2 side has a 6 pointer ...both 8 and 6 are stamped into the pointer ...after market dist by the looks of it .dont know where it came from its new .. ..........just before i took the tech 2 back .i cleared the codes .......bingo it popped the same codes ive been getting right after start ...ran for 3 minutes and started its misfireing again ... mrx ......i checked that out when i changed the timeing chain ,, thought aboult that ....it zero.s out ..SET THE DIST WITH COVER OFF .. ...its ok ,,darn that would have made it to easy .......cant get that lucky ...i inspected the sensor gear and key ways ..didnt see anything broke twisted .beat up or out of wack ......wished i did ...i checked the cover for damage ..hopeing to find something there ..nada ......... thank you ...keep it comeing if you think of anything else ...

MrX Posted April 12, 2011 Report Share Posted April 12, 2011 A plug exhaust or EGR that is stuck open can cause this problems to . With the scanner look at the EGR it will have EGR actual that should be at 0% if it off 1 or 2% it is open and cause to run bad. if you don't have the scanner you have to pull it off and the bolt you see on the bottom has to be flush almost sticking out a bit. To ck. the CATS. pull the front O2 it should run a little better Link to comment Share on other sites More sharing options...

KISS_Racing Posted April 13, 2011 Report Share Posted April 13, 2011 Ok guys, it has been a while since I have touched one of these. Complete shot in the dark (DUCK!!!!) I am thinking either TPS heats up and goes to nil even when open or IAC goes south. Again it has been years so guessing... Also, put fuel pressure gauge back on it to see what it is doing? I need a vacation day to come see you, I know you have heard that before. We just took on a project and or challenge last evening. Guy has met with several other companies over the past 5 years and has been let down. He has one of those "it can't work because it is too easy" inventions and people haven't taken him seriously. Please pray we can proto-type it, so we can sell it... Link to comment Share on other sites More sharing options...
