Check for continuity coming from the switch from the "start" position. If it is good, then the starter is defective, or a loose wire somewhere around the engine.
try replacing your your park neutral safety relay
check the injector, may be under the intake.
Try replacing the kill switch relay.
The fuel pump AND fuel relay (the relay being located under the steering wheel area under the dash and fuel pump located in the fuel tank) went out simultaneously causing my '94 Legend not to start at 150,000. After replacing the fuel pump, having the relay repaired and replacing the fuel filter, which is a good idea to replace the filter every year and right after replacing the fuel pump, mine started right up and I haven't had any problems ever since.
try replacing the delta pressure feedback sensor. this fixed my explorer.Or you can try replacing the relay.
It could be a loose battery terminal or dead battery! A faulty starter solenoid/relay will often only click once when tryong to start the vehicle.
I would start with replacing the signal flasher relay.
Try replacing the ECM relay in the box under the hood.
when you unhook the battery the computer probably resets itself.
1985 doesn't have cold start relay.
Not if it has an electric pump and a relay.
can a fuel relay fuse make car not start? If the fuse or the relay is bad, yes.
Check the starter relay on the right side above the fender the little red wire going to the top sometimes comes loose
where is the run start relay located on a 2006 Saturn ion
The same way you started it before replacing the battery.
Check wiring at starter Check battery cables for looseness or corrosion "Rap" starter with a hammer to see if brushes are stuck and need replacing Engine seized?
My 1990 Honda Accord had a problem of not starting when the temperature of the interior compartment was extremely high such as after setting in the blazing sun for several hours with the window up. I searched the Honda discussion boards and found that the Main Relay part number RZ-0088 has the fuel relay inside, also, and that replacing it will cure the problem. I tried it and so far so good. As I was replacing the Main Relay I noticed that it is placed about 1/8
There are various ways to troubleshoot smps of PC. SMPS stands for switching mode power supply. You can start by trying if it works elsewhere and if this the case, then it means that your motherboard is faulty.
There are many different reasons for that... It can be faulty fuel pump. It can be low pressure in the fuel line. It can be faulty fuel pump relay and etc.
First check the battery. Sounds like it might be dead. If it isn't the battery, it could be the starter relay. They are pretty easy to replace.
your fuel pump could be bad if it runs for a few seconds .
A relay is not essential but larger motors have a relay which operates above a certain speed, to cut out the start capacitor, which improves the power factor and reduces power losses.
sounds like you have a short,or a loose wire in the start switch,leaves a open circuit in the relay,hope this helps,ride on
