Gmc arcadia not starting


I don't know model year?
How long since a tune-up?
Any applicable trouble codes?
Make sure battery has a full charge and battery connections all good.
If it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs, gasoline engine. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. Only crank the starter motor a few seconds at a time, let it cool off a little.

New battery, new alternator, still wont start


    • 1 Ensure that your battery cables are properly connected to the battery.
    • 2 Start your car.
    • 3 Let the car run for around half an hour. Most cars idle fast enough that the alternator will be able to charge a battery while sitting at idle.
    • 4 Turn off your engine and test your electrical systems. If they work properly, your battery has been charged. If they do not work, or are sporadic, turn your car back on and drive around for another half hour. After the drive, your car's battery should be sufficiently charged.

I have a 1990 mitsubishi might max it wont run smooth unless you keep your foot on the gas and keep the rpms up a little bit and it wont drive cause it stalls everytime you try to move it. ive replaced the...


You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Troubleshooting the no-start condition - from the 1990 Mitsu Mighty Max Repair Manual:

Priority Action Part Type -- Cause
1 Inspect Battery -- Battery Discharged or Faulty.
2 Inspect Battery Cable -- Corroded, Broken, Shorted or Poorly Connected Battery Cable.
3 Inspect Distributor Cap -- Distributor Cap Cracked or Burned.
3 Inspect Fuel Filter -- Clogged or Dirty Fuel Filter.
5 Inspect Ignition Coil -- Faulty Ignition Coil.
6 Inspect Wireset -- Worn, Damaged or Faulty Spark Plug Wire(s).
7 Inspect Spark Plug -- Incorrectly Gapped or Fouled Spark Plug(s).
8 Inspect Starter -- Starter Motor Faulty.
9 Inspect Fuel Pump -- Low Fuel Pressure.
10 Inspect Solenoid Switch -- Faulty Starter Solenoid Switch.
11 Inspect Fuel Pump Relay -- Faulty Fuel Pump Relay.
12 Inspect Fuel Injector Pressure Regulator -- Faulty Fuel Injector Pressure Regulator.
13 Inspect Ignition Switch -- Improperly Connected or Faulty Ignition Switch.
14 Inspect Starter Drive -- Faulty Starter Drive.
15 Inspect Fuel Injector -- Dirty or Worn Fuel Injectors.
16 Inspect Fuel Pump Strainer -- Clogged or Dirty Fuel Pump Strainerat.
17 Inspect Engine Control Computer -- Incorrect Operating Information Being Delivered and Sent From The EEC.
18 Inspect Fuel Tank -- Fuel Tank Empty.
19 Inspect Carburetor -- Carburetor Flooded or Faulty Choke.
20 Inspect Distributor -- Worn, Loose, or Incorrectly Installed Distributor.

Have 99 mazda 626 sat idle for a year replaced batterty and alternator belt . cranks but won't start.


I would check to see if the car is getting fuel to the engine. Make sure your fuel pump is kicking on. Check to see if gas is going to the fuel filter from the pump. Make sure gas is going through the pump as well. You could also check the fuel pressure to avoid looking. Make sure it is in range. Also, make sure your battery terminals are cleaned and they are not loose. Make sure all the wires are tight and correct at the alternator. You may have an issue with the ignition system. check for spark. You may have a bad plugs or perhaps, a crank sensor or cam sensor. It could be anyone of these parts. You just need to do the proper test to eliminate all possibilities. If you have a question, just let me know.

My car wont start


a) Do you have crank no start? (see entire write up)
b)No crank no start ,No dash lights?, ( battery, battery cables, ignition switch,,starter relay)

If you have symptom A then the affected items are , ignition switch, battery, battery cables, starter, starter relay ,coil, coil pack, ignition module ,Distributor cap ,rotor, (if applicable) spark plugs and wires.
The best thing to do is to first make sure your timing belt didn't break. As long as the engine cranks you can do this. Give the battery a 3 min charge . Then have a helper crank the vehicle while you observe the rotation of all the pulley's and belts. They must rotate together. If the vehicle has a distributor remove the cap, ground the coil wire and remove fuel pump relay ( to disconnect the pump for testing)and watch the rotor as the engine is cranked. it should spin. If this is a-ok your worse nightmare is over.
Now we have eliminated the timing belt as being a cause. We now have to charged the battery again for three min and load test it( this is best done by a repair shop a load tester is expensive .If the battery if more than 5yrs old you may want to replace it.
If battery does not pass load test replace it.
Whatever you decide the rest of the items can NOT be checked out without a fully charged battery.
Check ignition switch and starter relay for B+ going to them and leaving them. Check starter circuit. Make sure B+ is making it to starter ( use a digital voltmeter). If B+ (12 volts) is making it to the starter and it doesn't crank then the starter is defective. Verify this by removing the starter and have it bench tested.
If starter cranks now your into coil testing . First thing reconnect the distributor.
Pull a spark plug, hook it up to a spark tester and ground it, now crank the engine if you get spark coil is ok and in all likelihood so is module.
If you don't get spark test for spark at the coil wire.
If you get spark here and don't get it at the spark plug wire problem is at distributor cap , rotor or spark plug wire. If plugs look bad use a fresh plug to do testing and naturally replace them.
If all of the above are a-ok.
Next is fuel checks. Reinstall fuel pump relay
Easiest fuel check is to put key into ignition cylinder and turn to on position. Lister for pump to buzz or hum. if it doesn't then check fuel pump relay for B+ going to it and leaving it and going to the pump. If B+ making it to pump and it doesn't turn on the pump is your problem. If B+ not making it to pump either the relay or the ignition switch is defective.
Naturally if the pump is defective have a repair shop do the repair . Its dangerous and a real pain.
Good Luck
Now the cutting out after running fora whilrcoild have caused by the coil, ignition module, fuel pump.
We kinda have to get the car to start first to be conclusiveas to why it cuts out.

Changed starter and alternator and still wont start on 1988 grand am


There are few things that you will have to check. 1) Is the battery properly charged. 2) Are you getting spark at the spark plugs, when you crank the car to start. 3) Is there proper fuel in the car. ---------------- If the battery is not charged properly the car will not start.Check the voltage of the battery .It should be exact 12volt. If there is no spark coming when you crank the engine then its the problem of either the spark plugs or the coil pack.the spark plugs gets power to spark from coil packs.Also check the fuel pump and fuel filter.If the fuel pump and fuel filter are worn out then it will not supply the fuel properly to the engine and this results in no-start problem. If all battery, fuel pump and spark plugs checked out OK then its time to check the wiring connections between the battery to starter and battery to alternator.This will help. Thanks. you can rate this solution and show your appreciation.

1989 Cutlass wont start


the filter on fuel pump might be clogged as well or fuel pump needs replaced

1996 S-10 cranks but no fire


did you check to see if fuel pump is pumping. fuel filter isnt clogged is it? but you're sure there is no spark. because if there is spark it could be air flow problems.
and you changed the ignition switch so that's not it, how about the starter. is there any noise coming from the starter when you turn key? if it isn't lined up right.
there has to be spark if you did what you said take off a wire at night and try it . electricity to start goes, ign switch battery starter(is there a relay on s10s cant remember), the alternator is here also.to coil/distributor to wires to plugs to gasoline

also it could be the wires coming from the battery , check them for corrosion. if they are really corroded could be problem. and make sure your ground is good contact. ive seen corrosion inside wires causing no spark.
just a few ideas to check.
