A fuel pump relay switch can cause your car to stall after starting. A malfunctioning fuel pump relay switch can cause your car to not start at all.
Yes .
possibly the relay switch
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
Where is the starter relay switch in a 1995 Nissan Quest? We were told it could either be the relay switch or the starter, because when we start our van and drive it and then turn it off, it will not start again for at least 5 hours. It does this almost every time we drive it. We have had the key/ignition tumbler replaced in it twice in the last four months.
Faulty horn switch, faulty horn relay, or a short to power somewhere in the wiring. Power should be constant at the 30 pole of the relay, and should only be present at the 86 pole when the horn switch is depressed.
If the clutch switch failed then the car will not start unless the switch is bypassed. The purpose of a clutch safety switch is to prevent the car from dangerously starting, so when it malfunctions that car will not start without it switch off.
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".
There are several things that can cause your 1992 BMW not to start. Make sure the battery cables and battery posts are cleaned. Make sure the battery cables on the starter are tight and clean.
might be starter relay, or the crank circuitry from the switch or to the starter from the relay. I would trace back from the starter to the starter relay back through the neutral safety switch to the ignition switch.
it depends on the year of the car, but on some older American models there is a relay switch (about a $3.00 part) that goes out and makes the car appear "dead". most back yard mechanics will insist it's the battery or alternator, but if your car has a relay switch I would spend the couple of bucks and replace it first.
Replace that relay that is connected to the pos batt cable; I believe that's your problem.
