240zwannabe Posted November 4, 2011 Share Posted November 4, 2011 I had an ignition issue and upon replacing the bad coil my starter is not able to crank the engine. I thought it was a faulty starter so I order one from Malaysia, I got it put in today and it's still doing the same thing. I then thought my battery had taken a **** on me, sure enough it had. I got a new one and it's still doing it! Can somebody please shine some light on me? It's an 1997 rb25det Quote Link to comment Share on other sites More sharing options...
Zinpieces Posted November 4, 2011 Share Posted November 4, 2011 First I'd put a breaker bar on the crank pulley and try to turn the motor. If it turns freely look into the electrical system. Make sure the ground connection is good and solid. If the motor is at all loose you might be able to turn it just by turning the fan. My money is on the electrical system. If you suspect the ground you can use a jumper cable from the block to the neg. post to create a good known ground. I've seen wires that looked good but were rotted inside so give things a good tug. hope this helps Quote Link to comment Share on other sites More sharing options...

I don't see it being the ground because the car ran just fine before hand. Quote Link to comment Share on other sites More sharing options...

neotech84 Posted November 4, 2011 Share Posted November 4, 2011 Put some 2 stroke oil in the cylinders in through the spark plug holes so you don't destroy your rings. Quote Link to comment Share on other sites More sharing options...
240zwannabe Posted November 8, 2011 Author Share Posted November 8, 2011 OK, today I got a chance to crank the motor over by hand and try the new starter out for real. It continues to lock up in the exact same position. It turns over exactly one time and just stops...AAHHH Quote Link to comment Share on other sites More sharing options...
Zinpieces Posted November 8, 2011 Share Posted November 8, 2011 OK, so what happens when the motor stops rotating? Are you able to rotate it again from the same spot or do you have to turn it backwards? If you rotate it backwards does it stop in the same spot? This all started with an ignition problem so pull the cap and make sure the rotor is turning. From there you have to inspect the valve train, make sure you didn't loose a valve spring or have a bent valve. My background is V-8's somebody who really knows these engines may be able to come up another idea Quote Link to comment Share on other sites More sharing options...

This whole problem arose while the car was sitting waiting for me to replace the steering rack, then the coil pack went bad and now this issue.

NewZed Posted November 8, 2011 Share Posted November 8, 2011 Exactly the same spot? If the timing mark was at zero, it would turn over once and the timing mark would again be at zero? How do you get it past that "same spot"? You don't back it up and start over, do you? How does it "crank over" if you're turning it by hand? You probably have a good description in your head, it's just not making it in to your thread. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted November 14, 2011 Share Posted November 14, 2011 Pull the spark plug of the cylinder where the distributor rotor is pointing and look inside. Quote Link to comment Share on other sites More sharing options...
Mike kZ Posted November 15, 2011 Share Posted November 15, 2011 Pull all the plugs out, and then turn it over with the starter with no compression. If it still stops you have a major problem Quote Link to comment Share on other sites More sharing options...
