Engine has no spark changed plugs wires an coil.Checked fuses nothing blown

NO ENGINE TOLD OR VIN told (it has engine codes) 1.5L USA?
1992, old car 30years old, and most have 10 problems not just 1.
when did this car run perfectly last, (last week, month,year ,decade?)
all spark wires dead, we do tests. here is the list of tests.
using tools.
check all fuses first, key on is best.
all fuses read 12vdc both ends, good, 1 side dead is blown fuse.
the ignition coil is hiding inside distrb, under the cap.
this old old engine is cam belt drive (rubber band) engine.
the belt fails at 60,000 miles and folks do not replace it and it slips/snaps and all spark is now dead. because the cam spins the Distrib. (dizzy)
see that, super common failure on all rubber band engines?
there is a way to test the spark coil cap off, using jumper wires.
spark dead causes (all 4 cylinders)

• a blown fuse (a 20cent part)
  
• cam belt bad (slip/snap or shredded ) over 60k miles SURE
  
• coil bad./(hV spark coil, dead)
  
• icm bad.
• distributor bad. or rotor bad ,missing or cap bad (shorted)
  
• there are more (wires bad) but this is lions share.
  

Does it have an alarm and immobilizer? If so, it needs resetting.

Check your coil connection. That is where you are getting your spark in the first place. Start there. Maybe the coil plug is not connected, or the wiring leading to the coil became loose. I hope you didn't disconnect the wiring sequence because if you did to make the job easier then you will need to get the firing order to make the spark work on time with the engine. I hope this helps. GE

There's a fuse for the igntion, if it's blown it would cut power to the coil, check to see if the coil is firing by putting the coil wire [ make sure the ciol wire is good, they are known to fail ] close to a grounded part of the car. if it's working, then it may be a bad rotor, if not it may be the coil.


It would be good to list what the vehicle is.

Hi.

Re:new battery and altenator
If engine turns over battery and altenator are OK.

Re:checked the fuses and found a few were blown.
Effectively those may be symptoms of a wiring problem. If a job had been carried recently, undoing and re-connecting the wires to access the part(eg. alternator) may have contributed to the problem.

Check all fuses, with attention to fuel pump fuse. Check the connectors to fuel pump, eventually read volts at pump and nsure that fuel is circulating
Check air intake and connectors to air intake sensors (MAF sensor), check connection to crank sensor and O2 sensors.

The blown fuses may also have been incidental. If you did not find anything, troubleshooting must proceed as usual, checking distribution, fuel pressure, and then factors that can affect the ignition.

Remember that after a prolonged and failed attempt to crank the vehicle, the cylinders will be flooded and the car will no start (wet plugs- no spark).

Check if there is spark on all cylinders. This can be done removing one by one the spark plugs wires and putting them near to the engine block while someone else try cranking. You will see the spark.
If there is no spark, then you have a coil/distribution problem. test coil by reading volts in and impedance (coil must not be open). I think this engine is not distributorless. Check distributor cap and wires. If you have disconnected spark plug wires after the problem, also ensure that wires are connected in right order.

Once you are sure that there is spark, check fuel delivery and engine control. This part will take longer.

I uploaded here engine control diagrams and other documents that may help.

if you noticed no spark you must have maybe put the plug wires on wrong this happens you need to get the firing order and trace that down, make sure all wires are put in correct order, Is it turning over, you didn't say mayber more details would be good.

if you have good coils and no spark are the wires ohming out to at least 28,000 ohms per foot?

Spray aerosol carb cleaner into the throttle body while an assistant tries to start the engine. If it runs for a few seconds then quits, you are not getting fuel into the engine. Check the fuses. You might have blown the fuse for the fuel injectors (possible if you removed any of the injector harnesses) or the fuel pump relay.

Hi my name is Allen!
Not sure how changing a water pump could cause a no start, but it sounds like the main Ignition Fuse may have blown some how, or you accidently knocked a connector loose some where. Check the PCM and make sure all the connectors are plugged in tightly.
