Car was running fine a few weeks ago now she turn over but will not start. Its not backfiring or flooding the plugs.
Few things I have check:
1. Engine have fire at plugs
2. Fuel getting into carb
3. Valves have been check over and over again
4. Timing is dead-on
5. Engine has compression
6. fuel pressure 5.5
She just turn over the starter but will not fire. I am confused!
I would definitely try starting fluid.
Best to have one person cranking and another person squirting.
If your carb is not tuned/choked perfect it will still start with starting fluid.
Also make sure your choke is not fully closed.
Look down the carb and make shure throttle plates not hanging up on manifold or carb gasket ; also make shure your shooters are getting fuel into the carb.
The butterfly is moving freely and fuel is squitring out into the carb, rotor is fine, I have taken that cap off to reseat it several times. I have spark at the spark plugs. I also double check to make sure it was not 180* out or off a tooth. I moved the plugs on the distributor counter-clockwise one and clockwise one, still nothing. I have watch the spark plug #1 fire while looking at the balancer which came on at about 18*. I am just lost to see why this car will not start.
So since it was running and you have not moved the distributor, the timing should be close enough to run, it ran there before.
The spark at the plugs, is it a nice bright blue or is it yellow.
It may help to try a little fuel in the carb to see if it fires. Maybe something is wrong with the gas you have or maybe someone watered your tank.
I would stay away from ether based starting fluid as it can sometimes fire without spark and can hinder the troubleshooting.
I have also seen bad msd boxes that will give a nice spark but at the wrong time. You may want to see if you can validate the timing with a timing light while cranking.
I may have found the problem. I took of my distributor cap to check my pickup OHMs rating which was 559 and look for any cracks. Everything look good with the naked eye but I can shake the cap while holding the 2 cap screws and something is rattling inside, so I call MSD tech line and they guy said It may be firing at the plugs but not a strong spark to start the engine. I just ordered a cap, rotor, pickup from Summit Racing. Stay Tune...
The distributor cap is not the problem; with the timing light hooked to the number one plug its firing at 21*. I am totally baffled on where the problem lies. Maybe I need to drain the fuel tank to make sure I did not get any bad gas. Everything else seem to be dead on with fuel pressure, compression, and spark.
I agree with t bucket, a little fuel down the carb.
If your running a HEI distributor check for a pin hole burnt through the rotor. It will cause an eractic spark and over looked by many people.
(note) have to remove the rotor to check it. look for a small burnt spot on the under side of the rotor.
I bought a can of Starting Fluid from Advance Auto came home sprayed it in the carb for 3 seconds then hit the ignition switch she fire right up.
I guess the gas I bought from Shell was bad or maybe condensation from sitting in the garage. We have been getting plenty of rain down south but my car never left the garage.
hows the gas does it have water in it? pump some into a glass jar i had this problem and the gas was the last thing i checked. my fuel cell had a bad gasket around the neck ring had 1/2 tank of water
Pump some gas into a glass bottle. If there is water in it it will be obvious. Starting fluid is not a good test, I have seen cars with no spark fire on starting fluid. Try a putting a little know good gasoline in the carb to see if it fires. You dont want to drin the tank for nothing.
