I have a 1997 mustang 3.8 that just up a quit has no spark or fuel anyone have an idea of were I should start to find the problem

 

Best and most efficient way to diagnose, is connect a hand-held scanning device to your vehicle's OBDII port.. It will display all trouble/error codes.. Once you get the codes from the scanning device, enter each code on google which will then provide a description as to which parts/modules are causing the error/trouble codes. This will provide a much better idea and solution rather than trying to guess what the problem issues might be. Then you can either purchase the parts and replace them yourself or provide the trouble/error codes to an auto repair shop and have them do further troubleshooting if necessary and replace the worn parts/modules for you. Meanwhile, hope you'll find the info provided as useful and also welcome aboard.

 

I would also recommend getting a hold of the shop manual for your car, as that has diagnostics, wiring diagrams, and connector locations that could be very helpful to diagnosing the problem once codes are identified.

As far as no spark or fuel, that sounds like a computer or wiring harness issue. Perhaps a fuse or two. But that's where the manual really comes in. One or the other would indicate a problem with either system, both indicates a shared issue, and that's the computer.

 

I forgot about the shop manual, so that would indeed provide the best solution along with the hand-held scanning device
