ecm blown fuse engine wont turn over
ok try this again i previously posted but it seemed confusing...
1st- 1991 camaro rs 305 tbi auto
i recently mistakenly went to wire a fan switch and didn't wire it correctly like an idiot i hooked the switch to the fuel pump relay instead of the fan relay oops is right..i'm guessing it fried a transistor or something in the ecm, as after it would not prime. so realizing what i did i hooked the fan switch up correctly works great....done with fan switch. now pump wouldn't prime so i hooked a hot wire from the battery to an inline fuse to a rocker switch and to the fuel pump relay(maybe problem i hooked it to the green and white wire in the fuel pump relay upon advice, maybe bad advice, should i have hooked it to the orange wire?). worked great turn key press button prime start, turn off switch...worked great for approx a month then started not working. the pump still primes with switch but car will not start. starter is new and working but STARTER NOT TURNING FLYWHEEL iTs just trying to grind off the teeth...thought maybe shim problem...no, tried shims to no LUCK AND HAS GOOD SPACING, its like something is seized up...checked fuses ecm fuse blown...uh oh...would a fried ecm not allow the starter to turn the engine over? possibly a blown in line fuse!?!?!? i assumed even if their was an electrical problem the motor would still turn over just not start...HELP PLEEEEEZ!

Re: ecm blown fuse engine wont turn over
ok...thanks for the input..figured id check some stuff...changed inline fuse going from battery to alternator. while doing this i noticed wire was corroded some (green and funky), but when i changed the inline fuse it seemed to give a more life started right up...tried it like 20 times in the course of 3 or 4 hours perfect evreytime fuel pump priming and running started as soon as i turned the key. now next morning go to start the car and click click click starter trying to turn but flywheel wont move same symptoms interior lights flashing while clicking takes multiple tries (10 minutes)for starter to finally turn over the flywheel, but when it does it starts right up?!!? is this a solenoid or corroded wires, ignition control module maybe..what would not allow the starter to turn flywheel?!?!? battery has plenty of juice, it doesn't even to seem to lose charge when attempting to start and this afternoon it took half an hour but eventually started like nothing was wrong...HELP!
