i just recently swapped a b20 and converted to obd1. my car was starting right up the last few days but today it will not start. the starter only clicks once. i took the starter out and got it tested and it passed. i changed the main relay out for a known working one. i sanded the contacts for the power cable to the starter. i bought the battery last week and it has started this engine about 20 times.

 

Is the battery dead? Has it been tested?

 

i have not tested it yet. the battery is only a week old. can they go bad that fast? is there any test i can do on it with a multimeter or do i need to take it to get tested?

 

Disconnect the battery connectors. Measure voltage across the two battery posts.

 

12.41 v

 

Does this^ voltage reach both the starter motor and solenoid?

 

Battery terminals clean and snug on the battery posts?

 

its reading 12.41 at the post on the starter where the power cable comes off the battery cable as well.

yes, the cables are snug on the battery as well

 

Is there continuity between the starter body and the negative battery post?

What's the voltage at the solenoid connector with the key in ON(III)?

Is the engine seized? Can you push start the motor?

 

I took the battery to get tested and it said the battery is good but needs a recharge. Cca was 440 and voltage read 12.28

 

Get a 19mm socket and ratchet and turn the motor over by hand and make sure it's smooth.

Also, check your grounds, and add some more as a temporary measure.

 

yea check the grounds. a bench test doesnt put load on the starter so itll pass if it kicks out and spins. probably just a bad starter man

 

i can turn the motor over with the 19mm on the crank. i changed all my grounds and keeping my battery on the charger over night. will update tomorrow. thanks for the help and all the quick replies

 

you were right. the test that oreillys does is obviously bs. bought a new starter and my car fired right up
