Have you checked for spark?
I would start with that… Diagnose for crank, no start…..
If getting spark, you may want to start looking at timing issues….

October 11, 2013 at 5:30 am #554308To be honest I forgot to check for spark I will do that and if it does on I will try the next step but I made sure the timing was correct when I put the belt on I think it’s flooding or something cause I took one of the spark plugs out and it has gas on it
October 11, 2013 at 6:32 am #554323Year make and model might help us a bit. But, if the timing is dead on and it seems like you are flooding, I would double check all electrical connections. If I had to guess I would say likely you might have a cam or crank sensor unplugged.

October 11, 2013 at 8:14 pm #554423According to Alldata the crank sensor is actually located on the back left of the head and runs off the camshaft.
Here is a link to autozone’s repair section http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0900c15280037f60
I would definitely start with that, if something is wrong with the crank part of the sensor, but okay with the cam part, you will get fuel pulsing, but no spark.
October 12, 2013 at 8:05 am #554551The crank sensor is built on the distributor
October 12, 2013 at 8:21 am #554558Can the distributor be installed 180 out?
October 12, 2013 at 8:52 am #554570Im not a mechanic, but with the help of the guys here I was able to rebuild my head and get my engine back together and running. From your post i was kinda confused. Is there fuel in your spark plug chamber?( where your plug wires push onto your spark plug) or Was the fuel just building up in your cylinder head and getting all over your spark plug? If so , sounds like an ignition issue. Maybe start with double checking your electrical connections at your distributor cap and at your igniters. Make sure they are completely seated and snapped in. As a side note for some of the guys here, is it possible he has his timing at TDC on the exhaust stroke instead of the compression stroke? Maybe try a compression test, the results seemed to point me in the right direction along with some advice from the guys on this site.
October 12, 2013 at 4:06 pm #554603First thing to do is check for spark. If it is getting spark, then verify ignition timing. If it has spark, fuel, and timing anywhere near right, you should get some kind of result, either it will start, or belch flames out somewhere.
October 17, 2013 at 1:05 am #555437Have you checked for spark yet? Given that you have plugs soaked with gas I would start with that. Also, you might leave them out for a while. That way the gas can evaporate from the cylinder. Too much gas in the cylinder can cause a loss of compression.
October 21, 2013 at 7:50 am #556394I’ve got it running but having timing issues what I did is adjust the distributor and it starts up it runs and shuts off a few times and when it’s running it not running correctly
October 21, 2013 at 7:58 am #556395Finally got it running by adjusting the distributor now it’s running rough almost shuts off when I push the gas pedal it my be still out of time but smoke is coming from the exhaust manfoid from all 4 cylinders when It warms up is that mean it still not timed right?
October 21, 2013 at 1:32 pm #556426The smoke is probably from trying to start it.
Put a timing light on it.October 21, 2013 at 5:40 pm #556432Is it it possible to have it on TDC on the exhaust stroke and not on compression stroke I just seen that on a post i just read.
October 21, 2013 at 11:28 pm #556473If your car runs, like College man says, check your timing with a timing light. Eric has a good video for checking timing. I also would suggest doing a compression check and compare your numbers with the compression numbers from the manufacture. Those results should point you in the right direction.
Now again im no mechanic by trade, just a DIY’er. Im going off my experience with redoing my head on my 98 Nissan Frontier 2.4L DOHC (KA24DE). After putting it all back together my truck would start, held idol with a slight shutter to the engine, and drove ok. Took it for a test drive and noticed it had a loss of power when going up hills. Would give it more gas and still loose mph. So i did another compression check and had 130 across all four cylinders. I thought good compared to originally having zero compression on cylinder #2. Which is what started the rebuild. But Wysteck and a few other guys here pointed out that those compression numbers were low and to double check my timing. I could have sworn i dialed my timing chains in correctly when i rebuilt it but guess what. My lower timing was good, upper timing was off one tooth on both the intake cam and exhaust cam. Got it re-adjusted and compression back to 179-181. No loss of power , and truck runs real good. So with some patients and the knowledge of alot of the fellas here , you’ll get it dialed in im sure. I hope this helps.
