Check the negative battery connection to the frame. If this is faulty, starting will be intermittent at best. Check the negative battery connection to the frame. If this is faulty, starting will be intermittent at best.

How do you bypass fuel solenoid?

Remove it first (typically just unscrews, may require narrow wrench and turning from the solenoid top). Determine the solenoid action (for example, when turning the key to on, does the solenoid have continuous power? Does the solenoid pin/plunger move up or down with power?). Permanently set the solenoid to allow fuel to flow, this can sometimes be done by cutting the pin/plunger part off, or pulling it out, there is a spring that may also need to be removed. Put the solenoid back in and make sure all seals are OK or add new ones. Note after bypassing a fuel solenoid, if you do not intent to replace it soon, you should install a fuel shut off valve when can be purchased from auto parts stores or big box hardware stores for 5-10 dollars. To prevent backfire, you would need to switch off the fuel and wait for the engine to stall which can take up to a few minutes. Turning the engine off with the key will still work, however you will not be protected from backfiring which can damage the engine. Turning the engine off by pulling the throttle back all the way will also not help.


Have a 1992 Dodge Ram 50 When you turn the key the lights on the dash come on but the starter does nothing you have had the Battery tested the starter tested you have replaced the ECM and Starter?

You should locate and test the solenoid. Most have three connections. There is a large cable from the battery to the solenoid, from the solenoid to the starter and from the start switch to the solenoid. The power terminals to the battery and the starter are large and have large cables. The starter switch connection is much smaller. Turning the key to 'start' provides a low current voltage to the solenoid causing the solenoid relay to close and power from the battery cable to connect through to the starter. If that voltage is present then the solenoid or the wiring between the solenoid and battery or solenoid and starter is suspect. If that voltage is missing then the starter switch or solenoid feed line may have failed.

Why are my cooling fans not turning when the fuse is good on a 1995 Cadillac SLS?

Perhaps the coolant temperature sensor isn't fucntioning properly, and not sending the proper temperature to trigger them. Sometimes the relay that controls them can go bad too. If you can, also try checking the ground points for the fan circuit.


The car has a strong battery power but does not start is it the starter?

it's easy to check the solenoid, put a screw driver across the large nut & the smaller one, and if the starter engages it's the solenoid .make sure the vehicle is in park, or the e- brake is on. ( with key on)
