Have someone start the car while another person sprays starting fluid continuously into the intake pickup/air cleaner. If the car starts up and then dies after you stop spraying starting fluid more than likely you have a fuel pump issue. Have the fuel pressure checked, make sure the pump is turning on when you turn the key to the on position without starting the car. You should be able to hear the pump whirring; if not, the pump is bad or you are not getting power to the pump. Check the fuses.

It may be the fuel pump. try spraying starting fluid in throttle body if it starts then stalls then its a fuelpump.

If you think its fuel, spray some starter fluid inthe throttle body. If it fires up, you have a fuel problem, otherwise, check your spark plug wires, distributor cap and rotor. Also, check your fuses.

1990 Cadillac Seville won't start. Is it the electronic control module?


Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

1997 mazda 626 won't start.


Are the plugs wet with fuel?
Check for spark. No spark? it may be the ignition module.

Plugs dry and spark present? No fuel?Spray a little starting fluid and see if it will run on that.
Then check pump fuses and for fuel pump noise.

Truck wont crank. we have put new distributor cap, rotor button, coil pack, plugs, wires, and fuel pump. we also checked our firing order.


you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.

1984 Ford F150 turning over but not getting fire


Good battery, good starter. Leaves spark and fuel.
1. Remove 1 spark plug wire from a plug. Hold near engine block while someone "cranks" the engine.
- Spark (yes/no)
If yes, issue is fuel. If no, remove distributor cap and check for cracks. Also clean inside to remove rust and dirt. Besure that inside of distributor cap is reasonably clean and rust free. After that, reinstall cap.
Try to start engine. IF it is exactly same symptom.....
Check input voltage to coil (high voltage source for distributor). Is 12volts present? If not, troubleshoot wiring between battery source and coil. Be sure to include the fuse for "ignition" in fuse box.
If yes.....Confirm high voltage is present at center (input) wire to distributor (CAUTION:- 30,000 volts could be present... do NOT touch bare wire.) Use insulated plyers or similar to place this center wire near engine block to check for spark. Note that this voltage source is powered on as soon as the ignition key is in the "run" position.

Replace coil if no high voltage is coming out. Replace distributor cap and rotor if high voltage is coming in to it, but not leaving and getting to spark plugs.

-------------
Confirm fuel is getting to intake.
I spray starting fluid into intake while cranking engine. It will "fire" if all else is good.
If it "pops" or fires, then you have a fuel feed problem... between tank and intake manifold, shoot fuel filter, fuel pump and otherwise confirm that gas is moving to intake from gas tank.

Good luck.

Wont start.


If it will turn over check to see if its fuel or fire. To check for fuel, spray quick start for a few seconds into intake. If it starts and stops. its fuel. Change fuel filter and check fuel pump. If it does not start its fire, Could be distributor cap, rotor, coil, spark plug wires or spark plugs. If it does not turn over it could be battery or starter. Check battrey connections, ground strap from motor to body and ground wire from battery to motor and body.

Engine will turn over, won't fire


There are only 2 things to make it fire: having fuel and having spark. Pull out one plug and have a helper to start the engine while you hold the spark plug touching the engine chassis to see if it sparks. If there is then open the air filter to put some of fuel in tho start. It if is starts then you know what the problem is. No spark, look for problem at the ignition coil , rotor and distributor cap. No fuel , look for problem the fuel pump relay behind the battery. Good luck.

I have a 1989 Chevy Blazer that is not starting. Will turn over, but will not start. Just replaced the fuel pump, spark plugs, and distributor cap/rotor. Please help!


First thing you need to do is to check everything. Make sure all the connection is connected. You want to check and see if you have spark and see if you can hear the fuel pump turn on. If you cant hear it with the key in the ignition turn to on(which the pump will be on for a couple of sec)check the pump and fuses. And if you do not have spark or fuel pump turning on, you may want to check the ignition switch which also supplies power to the pump and dis when key is in the on position or when trying to start.
