I recently acquired an 84 berlinetta that won't crink, the motor has been swapped from the original crossfire to a carbureted 305. I haven't really had time to really look at this car much, but I have begun to realise that whoever was the previous owner liked to jerry rig things into place. For instance the steering wheel has been replaced by a steering wheel out of a firebird.

Onto my question, When I turn the key to the start position, nothing happens. no solenoid click or anything. I was looking at the fuses, and the crank fuse is non existent, not even the metal tabs that hold it in place. Could this be the root of my problem, if so how should I go about fixing it? Any other leads on where to look would be appreciated! Thank you

 

I looked at the wiring diagrams for the crossfire , and they only listed 82 and 83 model years as having that engine ? When looking at the 83 crossfire wiring , it looked like that crank fuse supplied the computer with a 12V signal for the computer to use when the engine is , in fact , being cranked . Since you have a carb now , and are presumably not using the computer , the missing fuse shouldn't be the reason for the no crank situation . You need to check the large yellow wire coming from the ignition switch to see if it's got +12V in the crank position . If so , you then need to check the large purple at the neutral safety switch to see if it's got power when trying to crank . If you get all the way to the purple wire at the lug of the starter solenoid and have +12V present when trying to crank then you've likely got a bad starter solenoid . If you've got it at the yellow but not at the purple you've got a bad (or misadjusted) neutral safety switch . Like any wiring fault , follow the signal to where it stops , and the bad component will show itself accordingly .

 

1984 berlinetta would have been a CC Carb 305 not cross fire.

 

The CRANK fause was used with all fuel injected cars.

The only Factory carburated cars with the CRANK fuse in the fusebox were "HO" Z28's with a factory installed in-tank fuel pump. ( IIRC - possibly some 87's too. )

 

Hey, update: Traced ignition wire and neutral safety switch wires, had signal...went to hitting on starter, motor turned a little. replaced starter and battery and now the motor runs like a top thank you guy so much!
