My 1988 ford f150 will not start and if i put a new computer in it,it will work for like a week then go out again and i have to keep buying new computers
Hello, I am going to give you several solutions because I do not know which computer you are referring to. For awhile the cars and trucks had different ignition systems because the Pollution rules were different for Trucks.
If you have a Module on the distributor and that part keeps going out, there is a chemical paste which goes between the module and the distributor to handle heat. On the outside of the distributor the module is attached and through the body of the distributor it attaches to the stator.
If you can find a repair shop with a distributor machine, like a performance speed shop, they can spin your distributor and check the electricals.
Once you find out if the inside of your Distributor is correct and has no shorts you can look in other places for your problem. Check your Alternator Voltage if you do not have a Voltmeter on the dash and if you have an external Regulator check it before and after the connections. Replace if readings are too high. Later models had built-in Regulators in the Alternator.
Once you are sure the maximum Voltage is okay you only need to check Ground wires and lower Voltage feeds to the Ignition. Make sure if Resistor wiring is called for, that normal wire has not been substituted. A lot of times the Coil feed wire from the Alternator or Ignition will be Resistor type. Check a wiring diagram or ask the Autoparts store what is shown.
Your sensors may run at as little as 3 Volts or if a Ground wire is bad to something plugged into the system, that part may be grounding through your Module and overloading it. When you get your truck running, have a Starter draw test done to it. You can get a free scan for the onboard computer and a Draw test at Autozone, Oreillys, and Advance.
I hope you find that my solution was very helpful in fixing your truck.
