computer possibly fried, could it be anything else? cranks but no start.
What is your question?
i drive a 2002 ford mustang 3.8L v6. the engine in my car died as i was driving it, and it has not started since. i put a code scanner and received the code p0320, and that led me to replace the cam shaft sensor and the ignition distributor coil pack. and that didn't work so i had a mechanic come and tested out the sensor wiring and neither the camshaft or crankshaft position sensors were getting any signal. he then checked the fuses and found a blown fuse with a copper wire going across the metal forks. i bough the car in a auction so the owner before did this. the mechanic then tested all fuses for signal with a test light and non of them were getting any signal. the mechanic then came to the conclusion that this blown fuse with this copper bonding had fried the computer, therefore the car will not start. so i wanted to know if i should absolutely proceed to replace the ecm or could there possibly be another reason why the car wont start. i desperately need a second opinion!
What makes this problem better or worse?
the car cranks but does not start, un-drivable

Each and every fuse that can be found on the vehicle must be TESTED - this includes those big maxi fuses under hood as well as the relays .. Basic ignition spark test along with fuel pressure testing should be performed. We can’t possibly determine what the culprit is here ‘online’ - this must be discovered by actually testing the possibilities. You’ll need to have another *mechanic* or ‘qualified personnel’ do this testing along with more conclusive *hands-on* diagnosis.. PCM (computer) failures are extremely rare - I’d exhaust all other possibilities before replacement. Good luck!

thank you for the help! the mechanic that i had come tested everything such as the fuel pressure tests and the ignition spark test. he said that all cylinders and the ignition distributor were getting a spark. he then tested the camshaft and crankshaft sensor connectors with a test light, and neither connector was receiving any signal. thats when he proceeded to use a test light on the fuses and all of the fuses on the 1st fuse box were fine, but when he got to the interior fuse box under the dash, thats when he found that blown fuse i talked about, he then used a test light and tested each fuse, and not a single fuse was getting any signal. thats when he came to the conclusion that the pcm had burnt. i just want a professional opinion before i make any final decisions! -thank you! -Adrian
[[ According to the information posted here ]] The person you had testing your vehicle obviously was not experienced enough to reach a proven diagnostic conclusion such as this, At this point - the reason your Mustang stalled and will not restart could quite possibly be simply the inertia switch has tripped which turns the fuel pump off .. A simple reset is all that’s needed. As I stated in my first post, you need a *mechanic* to check your car out *hands-on* .. The PCM does not send power to the fuses. No power at all to the interior fuse box when tested with a test light is a very unlikely situation - the test light must not have been grounded correctly at the time - I do not see any mention of a ‘professional’ scan test or attempted ‘professional’ scan test - - something is amiss here. Good luck with the outcome!
