RB20 - Starting Help

Recommended Posts

Having issues with my rb20det. I'm struggling to even get it to crank. So far i've replaced the battery + starter, but when i go to try crank it struggles, similar to like what a dead battery would do

Checked the voltage on battery 13.4v, all the grounds are there. Is there something that could be draining the starter?

Check voltage at big 12V terminal on the starter. If it is too low, then your cable/connections is/are bad. If it is essentially the same as the battery, then the big power switch in the solenoid is likely to be f**ked up.

When I had a similar problem, turned out the starter motor was rooted. (I think I threw out a perfectly battery pack because it couldn't assist in starting the engine)

Put a new starter on and same happens

Will check the voltage it's getting, see about getting new cables for the battery

"New" or "another" ie second hand?

(had a similar problem with my Pathfinder - got second hand starter, and it failed same way in four weeks!)

Does it start easier once you get it started and the engine warms up? What is the battery voltage when the engine is running?

New, I managed to get a brand new forklift one that i've read people are running.

 

Doesn't start, just everytime i switch the ignition key, attempts to crank and then nothing.

Have you tried jump starting it?

Can you wind the engine over by hand? Either at the crank bolt or by pushing the car in gear.

Reason I ask, is, if it's not low voltage and it's not the starter, then the engine may be seized or full of water.

Another thing that will cause this is a seized alternator, ac compressor or p/s pump. It will make the engine turn over much slower causing it not to start. 

I see this often on Suzuki's with seized alternators.

I'm able to crank it by hand, and putting 12v directly to starter doesn't make any difference

I had this issue when I first swapped an RB25 into my gts-t. Check your starter signal wire, and also replaced the wire going from my battery to the starter, started right up.
