My 86 F150 Lariet
She has a newer engine and has acumulated about 40,000 miles and for 3 years I have fought this fuel/brain problem I think it's a pinched or partially broken wire in the wire harness. You buy a new brain and get 3 starts on the 4th the brain is fried she'll crank over but will not fire the brain is controlling the spark what is the best way to find and fix this problem????
Is this a good question?
