    Hi I was having a hard time Understanding your Question I Think I get it But tell me If Im Wrong.

    YOU CHANGED the Timing Belt and Now CYLINDER #3 Is Dead , And You are SURE OF the TIMING BELT SETTING am I Correct?

    OK If I AM Understanding you Correctly then your Next Step Should be To DO A COMPRESSION TEST ON #3 If you Read a Low or NO Compression there then ALL Of Them This Indicates that you Must have TAPPED A VALVE When it Initialy Jumped TIME in other words the Piston came up and Hit a Valve or more Causing SEVERE Damage to the Top End (HEAD). This Requires the Haed to Be Removed and the Valve or VALVES to be REPLACED , I Hate to Be the Bearer of Bad News to ya But these things DO Happen A Lot. Please respond if I Missunderstood you if Noe and this is Helpfull Then PLEASE RATE ME FAIRLY, Thanx so Much and Much GOOD LUCK with Your Honda.

    Truely, RejakWilson

You check the Compression PROPERLY ONLY 1 Way that is with a Compression Guage sir, your filger will NOT give You A Number such as 125 psi 80 psi or 0 psi you Need to Be Acurate with this
it is My Beliefe that You Bent a Valve om MORE when it FIRST Stoped running , Using your finger can only tell you if you have (SOME) or NONE Compression Again I hope this Helps you out wirh This Vehicle. And Please RATE ME If you feel ta Should Thank You Sir Have a Great weekend!

Hi Wilmer

Have you checked the compression on no 3 cylinder ?

Sounds like you might have a bent valve.

Do that first and let me know the outcome.

Good Luck !

Don´t forget to give me a FixYa rating if you think I have been of help, thanks.

John.

    Hi Wilmer



    Take out no 3 spark plug, screw in a compression guage, and spin over engine, a reading over 100lb sq. in. should be OK.



    If you do not have a compression guage, you can use your finger or rubber plug, pull off the other plug leads so it won´t start, and spin it over.

    You should feel the compression pushing your finger or rubber plug, out of the plug hole.

    If it is poor, compare it with next cylinder, and you will see what I mean.



    Let me know how you get on.



    Good Luck !



    John.

Drivers side has spark and fuel when using starter. But no fuel / spark when running on the passenger side cylinders? None of the drivers side cylinders fire!


are yous saying engine runs on 3 cylinders, (sure dead slow)?
great facts, so few post have actual facts or tests
but what engine, it's engine issues, which one?
must be v6, (left right bank)
but is it single or twin cam 24valves?
check all fuses first. (always)

lets see... one side has no spark, so did you scan he PCM while cranking for P03xx codes DTC errors. it will show them if you crank for 5 full seconds, and release the key , 90% of time.
and is a KEY fact in diagnosis, no need to fix cars like 1995 and older here. we use scan tools and win,.

left side has spark and fuel but is dead, so its flooding on that side.
right bank has no spark and no fuel.
you meant both sides dont fire. and engine does not run at all.
so what is wrong.
well I check spark first. is the timing good? if not the cam belt slipped. as all do , ignored.
5 min check and bam , OMG timings way off....
or check compression first. i do on all old cars.
for 2 reasons.
1:if compression is way off, the cam belt slipped.
2: if uneven , (done right) you go , gee, is this old car worth a rebuild? 13 years old, IMO , it is. but isuzu parts. hard to get?

do compression on #1 clylinder (or 3) first. if way off. bingo.
5 min work done WOT, wide open throttle.
bingo

line up
3.2 L 6VD1 SOHC V6
3.2 L 6VD1W DOHC V6 (w = 24v)
3.5 L 6VE1 DOHC V6

which one????????

knowing engine, tells the mech, what spark system is there and which of 2 fuel systems used.
see?
does engine have 1 coil pack with 6 lugs, or 6 cop coil packs.
see?

if compression is ok.
and one bank is dry.
that means the injectors are dead on one side.
and that means the PCM is seeing bad CMP sensor data.
some CMP can do that. but no engine stated.
SOme CMP sends camp pulses for all cylinders can can fail on one bank.
but if the cam belt slipped, some PCM go nuts with crazy CMP pulses.
let me explain if you were a PCM and the cam and crank signals.
are in contradiction, do you inject or not? (pretend that)
some do, some dont other guess wrong, or go goofy.

the spark and injections are all timed.
that is why I always check spark timing First.
a 5min job.
the new cars have no spark timing adjustments
and many think that is excuse to throw the tool away
nothing is so far from the truth...
learn this. and win...

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.

1995 geo prizm has no spark


like 10 ways to check spark, 1 being right.(DIY)
using a real spark plug, new as a test spark plug. x4
or #2 way with a pro spark gap tool that shows the energy level
how did you do it.?

no spark at all 4 spark plugs?
some have 4 COPS. does yours, and are all 4 dead?
question 2, when did it last run, right, yesterday or 5 years ago
and were things messed with , like a new timing belt.
and that brings up, does the cams turn.? if not you skipped the 60k tune up with belt.

this car is a 1.8L 7A-FE toy engine. you can fix it the same why.
and get great help with gen7 toy forums...
when posting state country, Canada cars (geo) are different
and state what engine, 1.6 or 1.8.. i think its 1.8 if USA
in USA the EPA mandated the 1.8 in 1995. but? country ?ou never said.
the 1.8 1995 has what is called an integrated ignition assembly
it has 7/8 low voltage pins (trigger signals from ECU)
it's very unique.
96 changes are radical here in usa for OBD2 (EPA rules)
see the spark tests here. (i hate AZ but not their docs)

their logic has 1 failing , does it fail for 1 cylinder or all 4
this is the #1 logic path after checking cam spins.

http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0900c1528006ef7b
Cops means DIS, Coil over plugs. and is Distributor less ignition.
the below toy idea is an odd compromise from old to new tech.
dizzy> then below oddity, then >cops. (history flow)
now MY way. (no cops, and only on this motor this year, uSA)

spark test:
1: does the twin cam spin? yes/no, if no, stop and fix that.
2: is spark timing (light) good on #1 or degrees.
yes, good, if dead skip to next
no, then the timing belt slipped, owner dont do 60k mile tunes. !!!
2: is spark dead, on 1,? only? yes, bad spark wire, or you using
a bad test spark plug, never do that, use a fresh test spark plug
and keep it in the tool box. (life time )
2a: dead one , the integrated, spark assy. is bad. 7/8 wire unit.
3:a; dead on all cylinders. (are you following me?)
bad inegrated module.
or bad inputs to it. there are 7 inputs (and ground)
no power to it. no 12v.
the inputs 7 wires are timing. if those are bad, then bingo'
then read the AZ page.

Dead cylinder....timming is right, getting fuel, spark is fine...compression test shows all cylinders are the same, good...the car only runs on 2 cylinders instead of 3...plugs and wires are new...


cant happen, you missed something, if you have spark, fuel and compression the cylinder will hit, go check again, when doing the compression test kill the spark and lock the throttle wide open. most common thing we see on the 1.0L 3cylinder is burnt valves most common cause is the wrong motor oil the valve lifters can not release the oil back threw the bleader hole if you use to heavey a motor oil, we see owners change the oil and use 10W-30 or 10W-40 and usely within 5000 miles the valves will burn, if you want to use the heaver oil then you need to replace the lifters with an updated part number that has the abilty to use the heaver oil.

On a rebuilt motor how do you set the timming on a 350 chevy. Thanks.


firing order is 1 8 4 3 6 5 7 2 remove number one spark plug its always the right drivers side head..closest to the radiator turn engine crankshaft till the top of number one piston is all the way to the top or if you have help put your thumb over the plug hole sand have someone bump the engine over till the pressure in the cylinder pops your thumb free,,,check front of crank  harmonic balancer for timing mark if you need to move crank by hand till the mark lines up to the 0...or top dead center....then make sure distributer cap is pointing to number one plug wire if not remove dist and turn to the right position and install...if it dosnt go in all the way dont worry hold light down pressure on it  and just bump the engine over and it will drop right in place then recheck your settings and install spark plug start engine and adjust with timing light check your specs

I have 1988 pontiac grand prix se with 2.8 v6 i have 3 spark plugs on the back and 3 on the front i replaced the the spark wire but i dont know what wire gose where in the spark coile


this engine is turned sideways in the engine compartment. looking at the front of the engine, where belts and pulleys are mounted, the odd number cylinders are on the left, the even to the right. starting from the front of the engine, counting towards the rear, the cylinders are numbered 1, 3, 5 on the left and 2,4,6 on the right. remove the spark plug in the number one cylinder and place a peice of tissue in the hole. now crank the engine in very short bursts. as soon as you hear the engine crank, let off the key. check for the tissue to fly out of the spark plug hole. once the tissue flies out, the number one piston is up. now you need to take the cap off the coil, and see where the rotor is pointed. hold the cap over the rotor to see which terminal lines up with the rotor contactor. connect one end of the plug wire to the corresponding terminal, and the other end to the number one cylinder spark plug after it is reinstalled. from here the coil terminals are numbered in a clockwise direction. the firing order for your engine is 1-2-3-4-5-6, so you just connect one end of a plug wire to the number two terminal, and the other end to the spark plug in the number two cylinder. repeat this procedure for the remaining wires,

Truck died while driving


IF THE TRUCK DIE ON THE FREE WAY AND NOW DOESN'T HAVE ANY SPARK THAN CHANCES ARE THE TIMMING BELT BROKE OR A TENTIONER FOR THE TIMMING BELT BROKE.GOOD WAY TO TELL IS IF THE MOTOR TURNS OVER ALL FASTER NOW THAN BEFORE THE TRUCK SHUT DOWN THAN THAT IS A GOOD SIGN THAT IS WHAT IT COULD BE. ANOTHER WAY TO CHECK IT IS TO DO A COMPRESTION CHECK ON ALL OF THE CYLINDERS, IF THEY ARE ALL LOW THAT IS WHERE I WOULD START. GOOD LUCK HOPE THIS HELPS

I put a 91 engine in to 88 body every thing fit but my engine wont start


Only three possiblities. no gas, no spark, or the timing of the 2. So first follow the full lines and disconnect and turn on the ignition. That will start the full pump. you should see gas flow. Next remove a plug wire and dont hold it but place it near a plug or anything metal on the engine. You should see a spark when cranking the car. Finally its the timming of the two. remove spark plug from number 1 cylinder, with a wrench turn the crank shaft around untill the cylinder comes to top dead center. Look through the spark plug hole you should see the piston top. Now take off the distrbuter cap and look to see which terminal the rotor is touching. follow the wire and make sure it is the same wire that goes to the number 1 cylinder. Of course if the distributor rotor isnt rotating then of course your timing belt is broke. Good Luck.

I had the timming belt done on my 94 honnda accord


The spark isnt controlled by the timing belt. The only thing that belt controls is the timing of the valves opening and closing. The spark is controlled by a crankshaft position sensor, or something like it. The only way i know how to check the timing of the valves is to take the valve cover off and observe the opening and closing of the valves as the engine is rotated by hand.
