1986 toyota pickup turbo engine problem
#1
here it goes and hope everybody understand what am trying to say
My problem began that i was having a hard time to start my engine, i found out that my cold start injector wasnt working trace the problem found that i didnt have good sensor for it and ground too for it while doing that found that that temp switch for ecu not working and the auxiliary air valve wasnt working too. after that my tps wasnt good plus the mass air flow sensor too and the ignition coil too. i also replace the distribuitor for a good one after that my engine would not start t all replace the knock sensor now my engine starts and just keep in mind that i had the engine rebuild 6 months ago everything is new inside the engine i got good compression 150psi for a turbo engine but now after replacing all that i got good fuel pressure new fuel injector that do work, spark at the spark plugs, timing is where is supost to be but my engine will only start if i move my timing to the advance position if i put it back where and how the manual saids the engine shuts down and it wont start if i leave it there i have to move it to advance to be able to srat the engine again but here is the other problem if i leave it in advance time and an talking about above the 15 mark it ill keep on but out of no where stops and here is the other problem when the engine start and stays on whe n i press the gas pedal sometimes it revs normal but sometimes the engines stops it doesnt acelerates and like i said i replace all the sensor, ignition coil distributor but the only thing i havent change is the igniter and ecu everything is eather new or in good working condition so please i need your help because i dont know what to do now
one more thing i keep getting code 11 on the ecu and out of ht 4 problem for code 11 that shows on the book i replace all the sensor but not the ecu whitch is one of the problems for code 11

stick to a single thread, rather than multiple threads asking the same questions.
get rid of the bold print, that makes the post difficult to read. make a better attempt to use concise sentences and sentence structure so that we can follow along and help diagnose the problem.

ok thanks for the info
rebuild engine 6 months ago everything new
replace all the sensors for new ones or goood working ones
the only one havnt change is the igniter or the ecu
got good compression, good spark, good fuel pressure, timing is on marks,
here is the problem if i put if i start engine above the like the 15 or 20 mark it will start
but if i move it to the 5 mark the engine turn off and i wont turn on ntil i move it back to the high mark
afrer changing all that but does 2 thing i keep geting code 11 from the ecu i erase and itd comes back
i hope i discribe the problem good this time and thsnks to everybody that reads this and for the help provided

Code 11..
Code 11 says you are in diagnostics mode and either your AC is on, or your throttle isn't closed, or your tps isn't adjusted properly.
...
If fixing that doesn't work odds are your valve timing is wrong. IE the engine wasn't assembled correctly. With the crankshaft key way facing up at twelve, your cam dowel needs to be at twelve also, this puts the dimple on the cam sprocket just left of too center..
If you get this wrong it doesn't want to run and if you get it really wrong your going to be buying new engine parts cause it will bend valves.

thanks man
i got the engine on the right timing now
now my probles is that whe n i try to give it gas it dies alittle bit then it goes and the whe n i let the pedal go stay rev hight
nd then out of nowhere the engine just stop and the nis hard to get it going again and some times is easy
