There is a timing kit for timing the focus one locks up the crankshaft and the other fits into the slots on the rear of the camshafts all the pulleys cam and crank dont have keyways they are freefloating when loose and if it jumped more than one tooth the valves are definatley bent and the head will have to come off

This what need to take place, number 1 piston on up position as compression stroke and both valve has to be close. The book should tell you the mark on the main crank pulley should be an arrow pointing straight up as compression stroke. Make sure you have all of the spark plugs out, it will make your life easy when you need to turn the main crank over to sit on correct timing. You cant not get the main crank wrong because one revolution is a complete cycle for the main crank. Other way to check if your piston is straight up, stick a plastic ink pen inside of the chamber number 1 and have someone turn the crack slowly with the wrench until you feel the top of the piston is up and match the mark with the main pulley and don't drop the pen. Next, the book should should tell you the marking on the cam gear (dot or arrow) marking where it should be sitting. Once the belt is on, test it by putting all the spark plug back in accept number 1 cylinder, you don't need to torque down the plugs, just enough no air will escape when the crank is turn. now stick your finger in the hole of cylinder number 1 and have a friend turn the crank over one revolution and you should feel the air is forcing your finger out because of the pressure. If you feel the pressure pushing your finger out, it mean you have and your on compression stroke. keep in mind you can be 1 tooth off either way and still have compression although the car will still run either its advance or ****** depending on the tooth sitting. you can tell if the car is tooth off and its retarding, by the sound when you adjust distributor back counter clockwise furthest it will go and it still bogging and pick up speed slowly. Play with your distributor rotating back and forth and make sure you rotate with small adjustment until you get the engine idle normal. The best way to tell if you set the timing correctly without using timing gun is, when you crank the engine and it start right up mean you got it right but close. after you have it set, still recommend to have it time using the gun making sure is properly set so you don't sacrifice the gas milage. Be careful to set the cam gear correctly, if not you can cause a major damage to your head and the engine. If the timing is off the pistons will hit the valves and bent it, then you will have to replace the valves, again its very important you have that timing sit correctly. 3 tooth is all the tolerance you have to play with. good luck, if you have more question let me know and will try to walk you through it.

Just have your crank shaft on the mark, and have #1 cylinder valves both closed, or, in the up position. (compression stroke) After you put the belt on, turn the engine over with a wrench, two complete revolutions. The timing marks should be exactly in the same place. If they aren't, you are out a tooth or two, and will have to try again. It should start up where it is, if you haven't moved the distributor.

Need more info on the make of car...but I'll try. The book should show you where the timing marks are on the crankshaft gear, and the cam. align these marks as in the book and insure the distributor rotor button is facing the number 1 spark plug. removal of the valve cover should show closed valves on the number 1 cylinder prepping for the compression stroke. Once timed rotate engine by hand to rule out piston/valve hit and feel for pressure at the spark plug hole.

I get a code of P0011,canshaft timming was advanced beyond limits,for a predetermind period of time.could you tell me how to solve this problem?


You didn't state year, make, model, or engine, but this DTC is normally associated with vehicles with variable valve timing. There are several possible causes including the camshaft(s) actually being out of time due to a slipped timing belt/chain, the variable valve timing actuator(s) not working properly, bad wiring or connectors to the vvt actuators, and ECM problems. Your best bet is to have it evaluated by a qualified shop. Your worst bet is to just start replacing components and hope you eventually get the right one.

Where are the PCM and the ECM located on 2007 suzuki Reno


yet another easter egg hunt.
why not pray tell, stated the DTC errors,. we cant guess them
they must be stated. win/win......
120psi is no good,
sure P0301,. is your only codes, sure.

my guess, lacking wet and dry compression, on warm engine
is #1 has burned valve.
did you let the cam belt run till it slipped.
ooPS that can be very expensive if you bind the valves.
it not run it , at all now. ID
1: check belt timing, by hand.
2: and do a cylinder leak down test on all 4, to see if the valves are bent now./
DOHC ,need respect.

misfire codes take heavy driving,
swapping ECU is not rational or needed.
the first ECU DID NOT LIE TO YOU!!!

2001 a4 FSI compression problem?


When the timing chain gets old, it will slip a tooth or two rather than break. When it slips, theengine msy or may not start, but the compression will be reduced. You usually have to remove the timing cover to verify the cain or belt has slipped, unless you have overhead cam. It that case, you only have to remove the valve cover to confirm valve timing.

Nissan xterra 2002 2.5L engine 4 cyl engine just stopped turn key can hear fuel pump turn on and spark plug and wires there's spark also checked compression test cylinders are fine 150 psi each also...


with a compression of 150 psi the timing belt will be in the right place so that can be eliminated . you need 3 things to make an engine run they are compression ( which you have plenty of --- fuel you can hear the pump but are you getting pressure in the fuel manifold and lastly spark. So have a pressure test done on the fuel manifold top check for pressure regulator --pump/ filter faults . Next check for spark at a plug lead. Check that the injectors are working . Missing just 1 of the 3 will not run an engine.

93 Honda Civic dx will not start. new fuel pump igniter, has spark


sorry if you guess and guess wrong. really, must be expensive.



ok got spark (and timing is good, timing light test)

if test fuel ( use instant start in a spray can) fails, with spark

then engine is bad, compression is checked, see near 80 not 150+ PSI , the timing belt has slipped. if not changed by the book

they slip and the engine grenades (or bends valves)



this is an interference engine, never ignore the belt.

there is an acid test order.

1 compression good.

2 spark good, and timed

3 fueling is last. (if spark plugs dry add fuel, by hand)



cant burn fuel with no compression and spark. well with EFI it cant run right with bent valves either.



here is Chad running an engine (any) with no gas tank

even his battery is dead. and has external battery. for 12v power.

a real trooper.

ive done this 1000s of times. in 60 years.

his engine only makes 80 psi (old) and still starts.

but EFI will never do that not that low. compression



the cam slips and goes retarded compression drops to near 1/2

and the valve timing is so bad, the exh opens late and pollutes the

next last intake charge. the card house falls and then the valve bend.



take if from me, nostarts are a blessing on any honda

maybe it saved your valves.? do the service on time./

We have replaced timming belt but cant get it to start


Double check and make sure you are set to #1 TDC then verify you have the timing marks aligned correctly. This happens a lot when the timing marks slip and the vehicle is 90 to 100 degrees out of time. If it were 180 degrees out it would start but run very rough. If you replaced the timing belt because it broke while the engine was running do a compression check or connect a small compressor to a line you can screw into the the spark plug holes and see if you have any compression or in 2 or more cylinders have no compression. If this test is true your valves are bent and you will have to have the head rebuilt.

My aveo 04 manual wont start gets a spark ,fuel and replaced timming belt it was chewd up after car stalled on me in the high way but still wont start. gears also shift into place whats wrong?


If the timing belt became chewed up it would seem the belt/timing has slipped (do not try starting it like this bad things could happen) You'll need to replace the timing belt, tensioner and insure the proper mechanical timing is done for it to run properly if at all. If the belt failed at highway speed and it has a interference fit engine this would mean a valve or two may be bent too. I'd check the timing and once this is corrected I'd checking cylinder compression.
I hope this may have helped,
Tom

1984 928 began running very rough & lost all power. Shop indicates 0 compression on 4 cylinders and that likely cause is slipped timing belt and damage to valves on one side. I thought 1984 engine had...


depending upon the rpm that the engine was turning at, I have seen "non interference" engines bend valves on a timing belt or chain failure.
if you have 0 compression on that bank, it will need to be torn down to find out why. BUT I would do a cylinder leakdown on those cylinders after the belt has been removed (so you can turn the cam and close the valves for each of those cylinders), to make sure that they are not properly sealing, before removing the cylinder head.
