MarkusZF said:My 1989 vette won't start, i have a new battery
When i turn the key everything lights up fine, fuel pump runs and i can hear a relay inside the car but nothing happens. It just won't crank. No clicks or anything from the starter.
found this behind the battery, the cables look bad and the one with the red arrow has a small bulge on it.
What are these cables? Anything to do with the starter?
With ignition on the security light doesnt flash but when you turn the key to start it flashes
have you checked that 5 amp fuse holder fuse?
it could be a VATS related failure but its could also be a bad ignition switch
for that mater have you verified ALL THE FUSES?
have you tried to jump the starter without using the ignition key?
are you getting voltage at the starter? what voltage does the battery show on a multi meter ? whats it change too if you jump the starter
youve got several independent but linked systems and sensors to deal with start by getting the starter to spin the engine,if you have the 12 volt plus current at the starter jump the solinenoid, if the starter won,t spin disassemble it and repair or replace it. then get fuel pressure in the fuel rails, ignition spark and injector pulses and maintain 39-41 psi fuel pressure and at least 10 psi oil pressure and at least 13.5 volts from the alternator and properly timed ignition spark
Id suggest giving both the starter and solenoid a good close inspection the starter or solenoid could be locked up, a couple hits with a plastic mallet and bye passing the ignition with the manual starter switch should tell you if the starter spins and engages the fly wheel if its getting the battery current?

a logical step by step approach will lead you to the problem, youll be amazed at what youll learn reading links.

every mechanic needs an ANALOG multi meter for testing capacitors with a micro farad scale, AND a DIGITAL MULTI METER

use of a shop manual and multi meter can be very helpful
every step can be broken down into sub steps that can be tested and isolated, when you find some component won,t function its almost all ways because of a bad connection, faulty sensor or a broken component that can be isolated and tested then replaced if found to be defective once your sure that its getting the correct voltage , engine vacuum or oil, fuel, pressure sensor input , resistance or mechanical connections etc.
yeah as a whole its some times a bit confusing and over whelming, but broken down into simple steps and tests its not nearly as difficult to trouble shoot or correct once the defective components isolated
VIDEO TO WATCH
clean the connection area carefully
use of a battery post cleaning brush tool is usually helpful
use of this common anti-seize paste on the connecting thread surfaces noticeably reduces corrosion and helps electrical conductivity

coat the cable connections with the proper anti corrosive paste
