To begin with while I was overseas my truck would not start so my wife got a battery and when they hooked it up the had polarity reversed. It shorted out the ECU. Replaced the ECU and it still will not crank and run. It will crank but shut off a couples of moments later. It seems like it is not allowing the injectors to pulse. It does have a code 23 and 24 on the ECU. My friend that is working on it, is a retired mechanic and says that he has checked all the wires and all seems well. Is there anything else you can tell me
