1988 Ford Truck no power at solenoid

you have to make sure that your battery is in good shape first. Then with a test light make sure that power goes to the solenoid/relay. then activate to see if the test light stays bright when the relay is activated. if not, then it's probably not getting any power to do so. It could be a fusible link that is burnt up. also try wiggling your shifter, it may not be hitting the nuetral switch right. Also next time say what engine it is. I'm sending a diagram of hte starting circuit. it is the same for all engine in a pickup luckily.....
