Remove #1 spark plug, turn engine to TDC #1 on compression stroke (you can tell this several ways--put plug in loose and listen for compression escaping, use compression gauge, stick finger in hole to feel pressure (not recommended cause as engine goes past TDC may suck finger into hole), or examine valves if cover is off-you should have intake closed and exhaust closed). There should also be marks on the crank pulley, but the TDC mark can be showing TDC on compression stroke or 360 degrees off on exhaust stoke. If this doesn't help, google search 4 stroke engine cycles.
Take out the spark plugs. Put your finger over the #1 cylinder spark plug hole and turn the engine over with a socket on the front crank pulley. When pressure starts to push your finger out of the watch for the timing mark on the pulley and stop turning when the mark lines up with the zero mark .
3 things 1, You have to check for gasoline, without there will be no starting. 2, Next check for spark by removing a plug wire and placing it near the metal part of the engine block. 3, Last is checking ignition timing to see if the timing belt has slipped. Take out #1 plug then use a piece of wire of something that will fit to see if the piston is all the way up when the distributor is on the #1 wire. post if you need further help
It doesn't matter, IF you have not disturbed the distributor. If the distributor is out, then when you put the cover on, the marks should face each other. Just to make sure, when turning the engine, put your finger over #1 spark plug hole, slowly turn engine, when air blows out, turn engine slowly to the timing mark and set distributor to point to #1 cylinder on the dist cap.
sounds like you have jumped time, you need to check the valve timing, most likely need a timing chain. remove #1 spark plug and put your finger over the spark plug hole and have somone bump the engine over untill the compression blowes your finger off the spark plug hole, then set the timing mark to 0 degress ( it should be almost there when the compression blowes your finger from the hole ) then look at were the rotor is pointing it should be pointing at #1 spark plug wire if not check the timing chain.....good luck
First you must determine is the engine is cranking and not starting or not cranking. If it is cranking, determine if it is cranking fast enough. If not, it could be due to the starter drawing too many amps or the battery is not strong enough to support the cranking amps. Once you have determined the cranking speed to be sufficient, see if spark is being delivered to the cylinders. If no spark, trouble shoot the ignition system. This should give you a start in determing the problem. If all is well up to this point, check to be sure fuel is being delivered to the cylinders via the injectors. If no fuel is getting to the injectors, perform a simple fuel pump operation test by turning the ignition to the off position and keepingt it in the off position for approximately one minute. Next turn the ignition to the on possition and listen for the operation of the fuel pump (which is in the fuel tank); you will hear the pump ticking for a few seconds until the pump pressure buids up then the pump will stop ticking.
An engine only needs 3 things to start and run. gas/ fuel air charge. spark and compression. you can check all three with little to no tools. #1 put the key in ignition and turn it on DO NOT CRANK IT. just turn it to the on position. Then go under the hood and look for a fuel bleed off valve which has a cap most times on it that is IDENTICLE to a air fed valve for your car tire, that is exactly what it is oif the cap is on or off it lloks exactly like the car tire valve. Find that, stand as far back as you can from it. Make sure before you push the valve down (like you are letting air out of the tire) that all electric things are off and nothing to cause a fire is within 5 ft in any direction from that little valve bleeder. Press it down just a quick second. Gas should shoot out or up or in any direction of that valve about 4 ft. remember this so you take correct percuations to avoid fire and or getting gas in yer mouth or eyes. If gas shoots out under pressure we will move on the the next one spark. get some type of metal bar or anything like that (screwdriver) that will slip in between spark plug and the end of the wire. set it up so, if it is sparking. You will be able to see the spark jump from the end of the wire Or what you stuck in there to make the connector stick out closer to being able to see and ground it. it should be a very small amount from some type of metal. then while cranking the car you can see the spark jump and know you have spark. and last is compression, pull any spark plug out, put you thumb over the spark plug hole. have a friend turn the engine over. do not push your thunmb on to that hole just set it there.,this because if all is good the intake stroke can **** yer finger into the hole and do something real nice like peel yer finger nail right off. as the motor is turned over about every 4 times around it should **** quite hard on yer finger and opposite that, it should make a load air pushing nosie. Those are the 3 basic ways to check for the minimums a fuel injected car engine needs to run. If you have all of those then it gets more complicated. most often if they are all good, it will start and run, most on board diaognostics have a fail safe built in and will run with the very minimums. if it wont, you are more than likey missing 1 of the 3
you will need to put the number one cylinder at top dead center. (front driver side cylinder) you can do this by removing the number one spark plug and place your finger over the hole then have a helper turn the crankshaft till you feel air push your finger. then look at the harmonic balancer and turn the crank to make sure the line on it lines up with the 8 on the timing tab. then position the distributor in the hole with the rotor button pointing towards the number one spark plug. (may be necessary to put a long screwdriver in the hole for the distributor and turn the oil pump actuator in order to let the distributor fall all the way in.) after it is in put sparkplug dist. cap and other parts back on ready to start and set timing. firing order is 1 8 4 3 6 5 7 2
take the spark plug out of the hole on the engine. the very front plug. have someone bump the engine for you. take the cap off of the distributor, and when your friend bumps the engine watch the way the rotor is turning. i think its counterclock wise. but anyway, hold your finger over the spark plug hole and have the friend bump -bump- bump the key until the air pressure "Pssst" blows your finger out of the hole. thats the compression stroke of your engine. and right now its set to send a spark to that #1 piston. SO look at the rotor, and pay attention to what direction the rotor is pointed. and when you put your distributor cap back on, your wire for #1 spark plug has to be pointed at the rotors tip, to get spark. so put cap back on, and then put #1 at the rotor tip, and remember what direction the rotor spins ? now put your spark plug wires on the cap to match the "firing order" The firing order is 1-3-4-2 with the cylinder closest to the front of the vehicle being #1 so if the rotor spins backwards . wherever the rotor tip is now ( since you bumped it to the compresson stroke ) on the #1 cylinder, you know where 1 is. now put #3 piston wire on the next plug, on the distributor then 4 , then 2. tighten everything, put the spark plug back in. and start your truck bro.
