starting cranking problem
I finished my motor build last weekend. b20/vtec turbo, but after test drive I had problems starting the car, I can start the car by push starting it, or with continuous attemps , car is getting sparks, fuel and air. problem seems to be power cut to the starting cycle.
things I've tried so far:
new distributor
new starter
new obd1 to obd2b ecu harness
new map loaded to the computer
turn on the ignition and wait for cel to go off, fuel pump primed etc.
symtoms are motor cranks churrr -churrr -churrr chop-- churrr -churrr churrr -churrr chop... it will do that until it starts or backfire from being flooded. during this cylce when the starter stops the volt meter will show low or zero volt for a second then crank again.
I've tried running a wire directly from the starter solenoid to the battery, with the ignition on it will behave the same, with the ignition off it will crank continuously, or wth power remove from the injectors it will crank continuously.
may I add the car runs great, drives great, and fast as hell, but there is a fault in the starting system.
I've done all th obvious so please don't tell me to jump the battery, check for fuel, timing, or sparks.
can someone help me

Re: starting cranking problem
Had a similar issue w/ a B18C n/a. It started having a starting issue. Found the timing was off and readjusted the belt. Started and quit running again after 15 mins and didn't want to restart. Then it would start when we push start but wouldn't w/ the starter. Ran fine and felt strong once started. After many testing we went back to the timing belt and installed a new one. Now it's fine. The old belt was just stretched out enought to cause a problem.

Re: starting cranking problem
I've checked cam timing, and everything is at TDC, using a new greddy timing belt. I've read multiple threads of LS/VTEC---B20/VTEC cam timing issues, never seen a article on how to fix it. for my motor the cam gears lined up at TDC while the crank is at TDC also, can the timing still be off?

Re: starting cranking problem
the problem is not with the ignition switch, today while cranking it came up with a TDC sensor in the S300 error code section, after it started I reset the code and it did not come back on.
on the weekened I will tripple check the cam timing. maybe the distributor is going bad also.

Re: starting cranking problem
How did you rule out the ignition switch? The ability to push start points to the ignition switch.
Ignore CEL codes that don't repeat.
If the cam timing were off, the engine would run poorly or not all.

Re: starting cranking problem
(I know for this guy is not a timing belt issue as he mentioned. But, just sometimes in a blue moon the obvious may not be the answer.)

Re: starting cranking problem
Check whether the G3 ground wire from the engine to transmission is clean and tight. If this ground wire is bad, the starter won't crank the engine.
Do the same for the critical G101 ground wire on the thermostat housing.

Re: starting cranking problem
checked the grounds, upgrade the grounds, add extra grounds.
still same issue, I am getting tired of it, order a new used dizzy since the tdc sensor code came on one more time, I still haven't rechecked the cam timing yet

Re: starting cranking problem
problem fixed, turned to be the distributor or something in it, I was using a ebay obd conversion harness when I discovered a pin came loose apparently the harness short something in the distributor, I swap to another and it seems to short that one also before I discovered the harness was bad. I put a harness in from xenocron and it was good but the distributors are both now bad.
which brings me to now I werend convinced that it was my ignition key, or grounds after I checked them so I bought a GSR one for $60 installed it today and problem fixed.
