Won't start electrically or manually

no engine stated.!

fuses good,? 12vdc on both sides key on?

spark good on all cylinders.??????????

this is first. not fuel, fuel is dead last.

if above is ok the engine runs on test fuel.

if the engine runs for say 3 seconds on test fuel, and SOUNDS

great, that means the spark and engine are ok, leaving>?

FUELING only.

easy , right?

if true all that, then the scan tool is next.

wont buy one,? like most here? (you cant fix cars with no scan tool)



make up or buy a NOID lamp. (a small 12vdc lamp)

see if the injectors are all firing.

if not, the PCM is cutting fuel.

if the injectors fire (electric pulse) then it may be fuel relay not closing.

did you check for 12vdc (11vdc min) at the pump? cranking

you must crank it and check,

there are 3 kinds of cars. (we assume last)

1: pump runs keyon, full time, (illegal now)

2: pump runs for 3 seconds, and stops keyon, (for priming only)

3: runs only cranked, (most cars) and runs running engine.



see that logic there?

some cars cut pump and injection with no spark. ( to cut fires)

this logic is inside the PCM brain, called firmware.

just assume the car is smarter and use #3 above. on all cars

and I win..



the scan tool will show errors cranked for 5 seconds.

does it?



now why i cant leave generic help and answer specifcially

no engine stated.

to fix them you need to know whats there, first.



the line up

1.4 L E-TEC I4 (petrol)

1.6 L E-TEC I4 (petrol)

1.8 L Family II I4 (petrol)

2.0 L Family II I4 (petrol)

2.0 L RA 420 I4 (diesel)





next time post the engine in your car.

open hood , look up see EPA sticker there and engine type?

USA answers... all. of mine, as this is a USA forum../

try to add to one post for one problem not make many unique posts. stay on NO START. please.

double anon posted. and this time no year.
ah but you cleaned it and now it dont run
sure,
well we can not guess all the things you did wrong. or forgot.
if you used a pressure washer , (bad that) then you have water
were water dont belong. think so?????
or put back wires wrong or for got to connect , some connectors.
if UNSTATED engine has spark wells.
they are full of water now and spark just hates to be underwater.

93 swift. what engine.??????????????????????

1.3 L M13A I4 (petrol)

1.5 L M15A I4 (petrol)

1.2 L K12B I4 (petrol)

1.4 L K14B I4 (petrol)

1.6 L M16A I4 (petrol)

1.3 L Multijet I4 (diesel)

Some times the extra amperage coming from the alternator the diesel motor will burn out the electrical components of a smaller vehicle. This is why you should never jump start your lawnmowers, motorcycles, or any small engine with a full size vehicle. Check your battery, then alternator, and keep tracing it back until you find the source of the problem.

Are you saying the starter is grinding but the engine is not cranking, or the engine is cranking and making noise and not starting ?

rechk plugs firing order. chk soliniod and coil r ok, rechk fuel is getting into engine- choking usually determines that, u can smell the over choked engine. I f engine turning & choked hold throtel to floor while cranking and leave there until it fires. if no firing happends it must be electrical. rechk electrical connections. Cheers

An ignition system is a system for igniting a fuel-air mixture. Ignition systems are well known in the field of internal combustion engines such as those used in petrol (gasoline) engines used to power the majority of motor vehicles, but they are also used in many other applications such as in oil-fired and gas-fired boilers, rocket engines, etc.The first ignition system to use an electric spark was probably Alessandro Volta's toy electric pistol from the 1780s. Virtually all petrol engines today use an electric spark for ignition.Diesel engines rely on fuel compression for ignition, but usually also have glowplugs that preheat the combustion chamber to allow starting of the engine in cold weather. Other engines may use a flame, or a heated tube, for ignition.
Thanks

Make sure you are getting spark at plugs. Coil may be going.

check the crank sensor or the cam sensor behind the pully,s to make sure there plugged in.

would help if more jnfo supplied as to wont start ? petrol or diesel? etc what other symptoms do you have ie does engine spin over as if no compression? any attempt to start ?

1996 sidekick wont fire up and start
