Most modern cars do not allow you to start the car until the computer has done a full systems check. While that may sound like a cumbersome task, this all happens at the speed of light and is relatively fast. The problem arises when your computer is not getting power to run those checks. No computer diagnostic, no engine cranking.

All it takes is for there to be one broken fuse in the EFI fuse box to completely shut down your vehicle.

That’s it.

Back in the day, a fuse being out in the electrical unit, unless it was the starter fuse or possibly fuel pump, would not hinder you from starting your vehicle. Modern cars, while making big leaps in safety, have yet to deliver, in my opinion, on the promises of computers revolutionizing automobiles. If anything, it is just one more thing that has to be monitored, checked and replaced. Adding more money to the cost of ownership.

Cars still can not fly, our miles per gallon has not significantly increased, and the ability to diagnose and fix problems has become even more difficult than before even with an OBD2 reader which often times may tell you the general area of the problem but not the problem itself. (i.e misfire on cylinder 3? Spark plug, ignition coil, direct injection issue?)

With inflation on the rise from decades of digital money printing it is becoming harder for the average American to service their vehicles. Thus, more and more repairs are being put off due to the cost of these maintenance items.

The only people potentially who can afford cars at this point will be the ones who can do their own maintenance or have the extra funds to pay someone to procure the necessary parts and tools to do so on their behalf.

That is slowly becoming a very small select group of people.
