Engine won't start

Help. I have just rebuilt a SBC and put into a Nova for a friend of mine. The engine will not fire at all. I have checked the wiring, timing setup, coil resistance, voltage to coil off and during cranking. I have spark at the plugs but the engine does not even try to fire. In many years of doing this I have never had this problem. The only thing I can find out of ordinary is that the guy has a Crane XR-i module in the distributor. This was in there before and the engine ran fine. However, in tracing the wiring I discovered that he did not have a resistor in the wiring as the crane instructions say. The coil is not a coil with internal resistance as it only has 1.3 ohms. Could this have caused the module to be damaged?

Any help is appreciated. Thank you

If you got spark it should fire. Pull a plug and see if you smell fuel on it. if you don`t, give it more gas, pump the carb at least 5 times and be assured the acc. pump is giving it a good pump shot.

Yeah if you have spark at the plugs you should get something..

Might sound stupid but make sure you have good fresh gas. Also a shot of starting fluid should get you fire.. If it don't then you can rule out spark and fuel.

If spark is good and you have fuel at the plugs, run a quick compression test on one or two cylinders. Over tight valves will give you fits as will an improperly set up timing chain/gears.

Is the dist firing at number one? Have you cold timed it to verify fire at #1? Just tossing out the basics when things don't made sense.

Thanks for the replies. Yes, I do have fuel at the plugs and have even dried them off because they were flooded. I have verified the timing by checking the timing mark on the balancer and the closing of the valves on #1 cylinder. I did a compression check and all cylinders showed within a pound or two of the same compression, 95psi. This is on a cold engine with no running yet. Still no attempt to even fire. I put new gas in the cell, but there was probably still some gas in there that was 3 or 4 months old.

Thanks again.

With only 95 pounds of compression, i'd be wondering what went wrong. It would be hard to fire with that low of a reading.

Does it seem like the timing is right? No unusual stuff going on like blowing back out the carb? Not 180* out? Valve adjustments all good? Im guessing it must be electrical or a timing issue. Could be a distributor issue as well.

If you happen to have spares you might try a different distributor cap and/or rotor. Go over the little stuff with a fine tooth come before you dig deeper. Chances are something will make it fire.

Put your timing light on 1 , turn it by hand , when lit, see where your timing mark is and check you valves to make sure they are closed. I think you will find your prob.

hope im not being rude by jumping in your thread here but i was just searching through posts to find out why my 350 spits gas out of the carb and does not fire up. i have already adjusted valves (2x) and double checked my firing order (countless times) i have been sticking an allen wrench in #1 till it wiggles the least amount and my mark is about where it should be then drop my hei in pointing at #1. this usually works for me and the car was running fine before. timing chain? i also heard a clunk the first time i tried to start it and now it wants to act like the batt is dead when i try to start even though i have 12 volts. can it jump timing? (roller chain 1 month old). motor is mostly stock 1979 350 in a chevy caprice
