hey i have a problem i acidently in a rush hook swaped the postive and negative cables on the battery and tried to start it i think i blew a fusable link. all fuse are fine but it wont crank over but if i jump the silinoid it starts just not with the key any sugestions?

Which poles are you jumping on the solenoid? If it's the small pole (signal pole) to the large pole thats connected to the battery +, then the solenoid and starter are good. If it's the 2 large poles the solenoid could be bad. You may be right, that you could have blown the fusible link that is on the wire from the + pole on the solenoid to the ignition switch. If that's the case, you shouldn't have any power to the switch, so nothing that normally comes on with the switch on should work. Hopefully you didn't also fry the PCM, but you may have done just that. Won't really be able to tell until you get the switch problem corrected. What year is your pony?

bring it to a shop. I think you've done enough damage.

i did that too i had to put a new alt and a new battery in because the battery wouldnt hold charge so start with those two things and it should work

That's rather harsh. A silly mistake perhaps, but a good learning opportunity, without a doubt.

90GTRagtop i crossed the two large poles i didnt try small to big pole i will tomorrow and i will check that fusable link you said i do rember there are like five links all goining to the big pole also i dont think anything else was hurt in the process cause all lights go on when key is turn and like i said i moved it to the run postion and i jumped the two large poles and started the car and moved it and for the person who asked me what year this was the car is actually a 88 cougar with a factory body kit which i bought a 351 to do a motor swap in i also have a 88 mustang gt .

replace the starter soleniod, it's only ten or fifteen bucks.....then go from there, remember neg off first on last....

If you jumped the large poles and started the car, that's great news. Means your PCM is OK. Try jumping from the large pole connected to the battery + to the small pole. If that works, your solenoid is OK, if not, you'll need a new solenoid. Also, if you have a test light or a volt meter, you can remove the signal wire from the small pole on the solenoid and have a friend try to start the car with the key. Check for voltage on the signal wire, it should have 12 volts when the key is in the start position.
