Car Forum / Toyota / Camry / July 2009Timing Issue
Im dealing with a 97 toyota camry, original problem was my oil pump was leaking severly. Took all the components off necessary to access the pump and replaced the seal. Replaced the old timing belt and when i tried to start it, nothing happened. Tinkered around some more and the cam is timed with crank, im getting air out the exhuast, fuel injectors are firing as well as the spark plugs, but also getting white smoke that smells little of gas, cranks just fine but wont run and get some white smoke out the intake. I have no clue of what to do next. Any help is appreciated. > Im dealing with a 97 toyota camry, original problem was my oil pump > was leaking severly.

Are you sure you the cam is not 180 degrees off compared to the crank (two crank revolutions per single cam revolution). You need to determine Top Dead Center for the #1 cylinder and then verify that intake and exhaut valves for that cylinder are both closed. Ed On Jun 15, 2:34 pm, "C. E.

Any other suggestions for the 180 idea? > On Jun 15, 2:34 pm, "C. E.

Any other suggestions for the 180 > idea? It might be more complicated than being 180 degrees out if the hatch marks, etc. were not aligned properly when you reassembled the front of the engine. Check out pages EM16-EM28 in the gen 4 manual. Not only does cylinder 1 need to be TDC compression, but some other pulleys need to be aligned properly as well (crank pulley, camshaft timing pulley, and oil pump pulley): http://camrystuff.com/index.php?page=Gen4_Manuals Good luck, MD On Jun 16, 12:31 pm, "yclept...@sc.com" <yclep...@verizon.net> wrote: > > On Jun 15, 2:34 pm, "C.

Do a compression test....

I don't think the 4 cylinder is an interference engine, so valves shouldn't be bent. The diagnostic table for a crank but doesn't start (page DI-28 of the manual in the link above) mentions ECM power source circuit, fuel pump control circuit, and the ECM. Incomplete combustion without a start says check the fueld pump control circuit. For an engine that cranks normally but is difficult to start, the chart says check the starter signal control circuit, fuel pump control circuit, and compression. Good luck, MD If everything worked before you replaced the old timing belt, then I'd first check all the things/connectors you had to remove to get to the belt. It's usually something simple. Try disconnecting the connectors and plugging them back in again. Check the ground straps. Making sure you lined up the correct marks on the pulleys. etc etc. Valves don't suddenly bend and piston rings don't suddenly wear out before and after a timing belt job. > Im dealing with a 97 toyota camry, original problem was my oil pump > was leaking severly.

Any help is appreciated. i'll recheck my connections again, did start up once but didnt idle right so i turned it off and ever since just couldnt get it started but i think it might be a connector as well > > If everything worked before you replaced the old timing belt, then I'd > > first check all the things/connectors you had to remove to get to the [quoted text clipped - 18 lines] > right so i turned it off and ever since just couldnt get it started > but i think it might be a connector as well So i put everything back together all the connections are good, timing is correct, spark plugs are firing injectors are firing no blown fuses, tested the major wire components all are in specs but now it sorta starts up for like 1 second then goes back to regular crank but no start. Im completely lost and confused right. made sure cylinders were not flooded and still not getting a start. :( |
