I finally wrapped it up last night and tried to fire it. Brand new bearings, rings, basically a brand new motor. This damn thing won't start, I had my battery charger on jump start and was outside for like 20 minutes hitting the starter and pumping the pedal and it tries to start and I hear it sputter like 3 cylinders fire and it just won't fire up. I did lube the cylinder walls when I assembled it, a buddy of mine told me it won't start easy until all the lube in there is gone. Im seriously getting frustrated. The opti is on correct, plugs are in the correct order, correct plugs, gapped @ .45, fuel pressure is good, datamaster is not showing any DTC codes, all sensors are functioning correctly. I have fuel, I have spark and all vacuum lines have been triple checked. Any tips on firing a new engine? I am so close to just calling some buddies and have them help me push start it.

May try bleeding the fuel rails. If it was me I would check the usual...fuel and ignition but it sounds like you already have. Maybe double check the plug wires for proper routing/firing order.

Done, done and done.....=/

Not that it would make a diff, but shouldn't your plugs get gapped at .050.

And I don't believe you should be pumping the gas.

Are to smelling any fuel (like flooding out)?

Is your TB hooked up right and nothing binding?

If you not firing on all 8, I'd check each wire and plug to make sure the are on and not cracked and also make sure all your ignitions are grounded correctly.

Good luck.

Defaintley smells like its getting flooded. I didn't mean to say only 3 would fire, but thats the most I could get to fire and it almost started. Everything as far as the distributor and wires are 100% correct. Its also a brand spanking new opti. I did however put #42 lb injectors on the other day that I bought. I tried starting it at the stock injector rate of 25.9 and wouldn't fire with the same result, I then set the injector constant to 32.5#'s. I got a good friend who is saying I should set the injector rate int he PCM to 42# since this is what their designed to do and I should get even spray this way. Thoughts?

I don't know if it would have any adverse affect, but those are pretty big injectors. Maybe they're too big for the PCM to compensate without tuning.

I'm certain I don't know what I am talking about, but still, I wonder why such large injectors. JMHO

I have a cc306 and plan on going with ported heads, not only that but I got these for a really good price. when I said I set the injector constant to 32.5, thats me tuning it . Im not running them at #42. Thanks.

Think I may know what it is, I believe my valves might be too tight and the fuel is dumping into the cylinder walls and the valves are not opening enough to allow it to escape. Basically the only thing I havn't double checked, i'll give that a shot when I get home, thanks everyone.

I just did a cc306 swap and that is exactly what happened to me. I have heard you should pre pump up the lifters before installing them back in the car. This prevents having to readjust the valves over and over. Do a search on adjusting your valves and one way I have seen to do it is don't tighten them past zero lash at first so that they are loose. I think my problem was the lifters kept pumping themselves up making the valves really tight. Try this. No expert here but its worth a shot.

first thing to do is take the plugs back out, and clean them with a torch. use compressed air (if available to dry out the cyl.s of any fuel that may be in there). DEFINATLY DO NOT PUSH START IT! its not goin to help. the eng. should fire right up if everything is ok. doesnt matter how oily you had the cyl. walls. it should still start unless you had the cyl.s filled with oil. that would be good. and, you should NOT be pumpin the gas pedal. thats causein extra fuel to enter. dont hit the gas pedal at all until it starts. thats the beuty of fuel inj. it already adds enough air to start it.
and, the 42 lb inj.s are WAY too big for you. they shouldnt prevent the eng. from starting. and, Im not a tuner, but seems to me if you tell the pcm you have smaller inj.s (you mentioned 32.5) that it would spray too much fuel. picture the inj. as a hose. a 30 lb inj. is a standard garden hose, and a fire hose is your 42's. if you cycle the two the same amount of time, the 42 will spray way more fuel. so the pcm thinks its spraying a determined amount of fuel, but by having bigger injs. in there then it thinks, its act. delivering more fuel then it needs. poss. flooding the eng. and preventing it from starting. I would start it with the 42 in the programed in.
and remember, an eng. is just a machine. if everything is correct, it will start right up. if its not starting, somethings wrong. do you have a stock tune and stock inj.s to throw back in there to try to start it? Id do that. stock inj.s would be fine on a cam only engine. 30 lb injs. is all you'll need once you port the heads.
chris

very good point. its very poss. you dont have any compresion due to the lifters being adj. improperly. didnt you preprime the eng. before you put the intake on? if not, thats a good poss..
chris

Yes, lifters we pre-primed. I also unhooked the pcm and used the starter for a good 10 sec to prime the oil pump. I have confirmed by pulling the plugs that is it flooding the engine. I also loosened the valves a little bit and confirmed this isn't the problem. I did unplug the injectors and hit the starter for a good 10 sec to try to burn off some fuel. Put them back on and tried to start it and almost got a complete firing order. It wants to start. The problem definatley is too much fuel. I'll try setting the pcm to run at 42# injectors and I also bought some starting fluid to help get her fired up. Wish me luck and thank you all for your help.

Check the lifters. I have done this. Just go readjust the rockers to be sure. But the PCM needs to know what size injector that it's firing. Do those two things and it should fire up for you.

I set my injector constant to 42 lbs/hr. It runs good with that setting, even a tad rich. I suggest you change the injector constant to 42 or switch to the stock injectors.

the only way to clean out the cyl.s is to take the plugs out and clean them with a torch, then maybe floor the fuel pedal and crank the eng. over to clear out the cyl.s with the air (holding the pedal to the floor while cranking will enter the pcm into clear flood mode, and the inj's will not fire while cranking). then reinstall the plugs. dont forget to unplug the coil while crankin so there arent any sparks when the fuel is being blown out the sp. hole's.
