Replaced camshaft sensor, crankshaft sensor, balancer belt, timing belt and water pump and it still will not fire...help
Good post Kelly. Just a note. Gallants are very particular. Timing has to exact. If the timing belt broke, then they are looking at an engine replacement. Interference engine. It will break valves and /or punch holes threw the pistons(compression test). One more thing to look at is the catalytic converters. This will also close off air flow.
If you have no spark then you need to track that down. The cam and crank sensors were worth changing but none of the rest of it will have any effect on it firing ( the timing belt will just make it fire at the correct time but won't cause it to not fire at all) you need 4 elements to have the engine run so check for each of these... 1 would be fuel. Check that you have the Correct fuel pressure, 2 would be air. Ensure that the air filter is not so clogged it can't breathe (not typical in the automotive world but it is possible) 3 would be compression in all the cylinders and 4 is spark to ignite it all. The other not so common thing to check is that there isn't something in your exhaust pipe or the pipes aren't bent keeping it from exhausting. Let me know if you have any other questions

Check that the fuel is getting to the engine and the sparkis presentm if it is a gas/petrol engine that is. The spark and fuel must be introduced into the combustion chamber simultaneously foran engine to work.
If one is present without the other the engine cannot work.So check that the fuel is getting there by slightly loosening one of the plugs and turning over for a good while ...then quickly remove the spark plug and check to see whether the end of the plug is moist with fuel. If it is not quicklysniff the spark plug holechecking for the smeell ofgas/ petrol... if you can smell it the n that is onepossible causediscounted.
Thenpush the removed plug into thewire associated with it and place the tip close to a metal section of the engine.....do not hold it.....
Withsomebody cranking the engine over observe the spark produced...if a spark is produced make note ofwhether it is a healthy, visible spark... If it is that may be another cause discounted.
If the spark is ok and the fuel is ok thenyou need to check the timing, that isyou need to check that thetwo elements are introduced into the combustion chamber simultaneously
This can be done by a mechanic if you cannot check yourself. A mechanic may be able to makeadjustments to the fuel supply and the spark to make them coincide thereby making the engine work.
Ifduring the above process you find that no fuel is getting to the combustion chamber , or whetherthe injection of fuel is a weak one , you must seek to ascertain what the cause of the bad fuel supply is.
Maybe clogged fuel lines orfuel pipes impeding the flow.
Maybe aweak fuel pump not delivering enough pressure.
A malfunction of any ofthesensors associated with the fuel system that lead to no or bad fuel delivery. These include thecrank position sensor, the cam position sensor, the throttle position sensor, the electronic control unit, the sensors attached to it, etc.
If the spark is found to be weakyou should try changing plug wirres/cables
If that has little effect check the distributor cap/rotor arm for condition.
If that is okay check the coil or coil packs.
Remember thatthese are onlysome of the potential causes ofnon working engines,
Could it maybe the coil not firing
Fuel, air, spark or timing....Check to see if you have fuel in the culinders(wet plugs). Check your air filter ( clogged), plugs (worn), wires (worn), distributor cap/ rotor (worn). Check fuel filter (clogged.) Make sure your timing is set to manufacturers specs. Check for loose/ worn / corroded wiring and connectors.
Take out the plugs clean the contact (spark)points with something abrasive,put them back in.Start 'er up!
Lesson in life...
Keep it simple :-)
Ignition control module should be the issue if not try the EFI relay.

Was the belt you replaced broke? Did it run before you replaced the belt?

you should check the compression. its the easiest way to make sure you didn't bend valves. alot of times when the 'B' belt breaks, it gets sandwiched between the 'A' belt and crank sprocket, causing it to jump time.
SOURCE: HELP!!!!need timing marks for pajero 94 2.8 auto *** import
there is a little mark on the crankshaft which you line up with the 'o' mark on the casing ..
remove the cam cover and look at the cam you should see a nob on the cam about 3 th lob and that should be facing just left of the engine ..
if you have a turbo there is two notchs on the injection pump pully ..if turbo there is a 't' mark on the rear of the cover the notch on the pully should mark up with the 't'..
the timing is set..

Hello and welcome to FixYa! If you have overheating problem, it can lead to multipleissues. You may be running on low coolant that's why the vehicle overheats. Ifthat's the case, please add coolant and make sure that it sits on the rightlevel, too much coolant can cause overheating too for coolant will overflow. The vehicle may have a faulty or worn out radiator blowermotor that's why it overheats. If that's the case then you will need a blowermotor replacement to resolve the issue. If the radiator is clogged with dirt and rusts this issueoccurs too. The coolant doesn't flow normally on the cooling system if it'sclogged. If that's the case, I strongly suggest that you have the radiatorflushed to drain out dirt and rusts. If you think that the radiator served youenough then it's better to have it replaced. Please do check the radiator hoses, If you have worn outhoses it can cause coolant leakage which can result to overheating. A tiny holeis good enough for the vehicle to overheat. A faulty thermostat sensor can cause the issue too. If youhave worn out thermostat, the fan may not trigger that's why the fan won't workwhen under stressed conditions. A blown radiator blower fuse can cause thisissue too so I suggest that you check the radiator blower fuse and replace itwhen necessary. What causes the radiator blower fan fuse to blow? It's becauseof a failing radiator blower motor, If that's the case have the radiator blowerfan motor replaced. If the fluid in radiator doesn't circulate then it meansthat you have a blown head gasket or a faulty water pump. I suggest that you gofor the water pump replacement first specially if you think that it's near theend of it's service life. Usually, water pops out the radiator when engine isreved (a sign of faulty water pump and possible blown head gasket). Hope you find this information helpful enough and thank youfor using FixYa! Have a good one!

When we checked the timing belt, we found that the balancer belt was broken, and appeared to have moved the timing off a little. It was running and just quit on the way home.
If the belt broke/split apart. Then the engine is gone. I have never seen one survive a broken belt. If you lost a few teeth and the engine still turns over, replace the timing set, all of it. If the water pump is in with it it, replace it also. It will run a couple hundred in parts, but you only want to do this job one time. Also get a manual and follow it to the T. A junk yard engine for these are over $1000. Because it is hard to find one that isn't trashed from the belt breaking.
