I have a 93 Suzuki Sidekick and it wont start either. The spark seams to come and go. Also the spark seems like it is late? I have replace the timing belt the Coil and the ignitor on top of the coil as well. The compression also is fine.
did you check for spark at the coil when it goes?
does test fuel start car.
is car flooding? look at plugs, wet and stinks of fuel?
bad fuel
bad cam timing.
bad front of crank key way , sheered or mangled thowing timing way off
flooding, try WOT cranking to clear fold , WOT shuts off all FUEL on kicks.
miss timed Distributor.
horrible bad need of a tune up.
Go back to the basics, look at fuel delivery, ignition and compression. If you have all 3 and everything is adjusted properly, the engine will start. Try spraying a little starting fluid into the air intake while someone is trying to start the engine. If the engine briefly catches while you're spraying starting fluid, the problem is fuel delivery.
A cracked or broken piston will cause a loss of compression, as will cracked or broken rings. The failure of a head gasket will also cause a loss of compression, as will broken, cracked or badly worn valves or valve seats. A crack in the cylinder itself (either the sleeve or the engine block), or a crack in the head itself will cause a loss of compression. A problem with the plug threads or the threads in the head (for engines that have plugs) can cause loss of compression, and injectors (for engines that have them) can leak around the threads, either because the injector threads or the threads in the head have been damaged.
Have you checked for fuel and spark? Fuel pumps ad burnt ignition rotors are very commen on these vehicles
Problem with the emissions controls. Have it checked for codes.
You need three things, spark, fuel and compression. If you have replaced EVERYTHING spark related and fuel related including injectors, I would do a compression check next, you may have a valve problem.
get the CEL checked and fix the problem. Disconnecting the battery for 15 minutes will reset the light on an OBD1 vehicle.
thats a little on the worn engine side of compression,but that in itself would not keep it from starting....most likely a fuel or spark problem. you can check fuel pressure with a screw in guage from autozone,and check spark with an inline spark tester from autozone.
Check compression, fuel delivery and ignition. The easiest thing to try is a little starting fluid down the air intake while someone is cranking the engine to start it. If it starts briefly you probably have a fuel delivery problem.
that would be a compression problem.
The problem will turn out to be either fuel delivery, ignition (spark) or compression. If all three exist in the proper amounts/timing... the engine HAS to run.
Typically, it's not a problem if you wear compression socks while you on bed.
What problem?
PULL OUT PLUGS CHECK FOR CRACKS @ GAP
You might have cellutitis. Go to your PCP and get it checked out. It is a form of infection and the doc will prescribe some antibiotics along with some ace wrap to make a compression wrap around the legs.
Doubtfull. Low compression would be a mechanical problem.Doubtfull. Low compression would be a mechanical problem.
Usually a problem in the emission control system - have vehicle scanned to determine the problem
briggs doesn't offer compression ratings for their engines. I will usually pull it 3 to 5 times and look for 90 to 120. anything less is a problem and if it doesn't hold compression there is a problem
