Replaced the brain box,but still wont start

Yes unforunatly, unless you know of a good repair shop that has the proper equipment. The thing is you vehicle may run with just a junk yard "brain box" (powertrain control module or PCM) but it wouldn't have the correct info in it (VIN gor that vehicle or mileage etc...). WWhat's cuasing the vehicle not to run is the anti theft. Your vehicles keys have a transpoder or chip in it that goes to a "brain box" (Sentry key immobilizer module or SKIM) that in turn sends a signal to the PCM telling it that nobody has just broke into the ignition switch and is just turning it with a screwdriver or something. There is really no way to bypass it either. Wish I had better news but I hope this helped

Brain box problem

Hello Bright, I won't even begin to act like I know what a brain box is, but I would say if the car means as much to you as you sound like it does. Then have another Auto Electrician have a look at it or troubleshoot the problem yourself. A good electrical repair manual found online from Mitsubishi will most likely tell you how you can verify the report given by the first electrician. I myself would just rather have the "no fuss, no gadget electronic system in a vehicle. Give me the cars from the 60's to the mid to late 70's." I am one happy camper then! You know the 62NOVA, 65Pontiac GTO, 68 Chevelle Mailbu and let's not omit the 69 Judge and Super Bee. Those are cars to work on Ssswwweeeeeeeetttttt!!! Good luck

I have a 1988 ford 4x4 five speed 302. I had a guy put a motor in it but he says my fuel pumps keep pumping gas and never stop. He thinks its the brain box. Does the brain box have to match the motor or...

yes it does and your so called chancer of a mechanic should know how to cure it by rewiring the pump relay through the ignition switch ,If he doesnt know how to cure it in a few minutes work then dont pay him ,simple ,enough unskilled cowboys out their giving the motor game a bad enough name without help from you --honestly can anyone work as a solicitor without a degree and membership of the appropiate organisation ?? yet any person can set themselves up as a garage and put peoples lives at risk .
