i did tune up on my suburban the other day and now it wont start. its an 85 with the hei and all that jazz. i replaced the cap, rotor, plugs and wires. it ran before the tune up and now after it wont even kick over. i removed all the plugs and they were washed with gas. when i removed the number 7 plug alot of fuel came out. we dried the plugs off and re-installed and still nothing. its getting fuel and spark but its just not starting. its really odd. im almost gunna give up on this thing. any ideas that i can use to possibly get this thing to start. im going to take the plugs back and exchange them for new ones. the firing order is correct. i just cant for the life of me think about what it is. and i know its prolly something stupid.
 
the coil was replaced last time i did a tune up. when checking for spark i seen that the spark was a blueish color. its an accel coil from auto zone. it has spark and fuel but just wont fire for some reason.
 
you say its getting a lot of fuel and it was dumping out of the spark plug hole when you took one out eh? thats not good..

Try holding the gas pedal to the floor while you crank it... :D
 
havent checked timing yet. thats what i think it might be. the distibuter was a little loose and i didnt find out till after i accidently moved it. i had my boss crank it over while i slowly turned the distributer and nothing happend. the cam is turning, we took the cap off to check if the rotor was turning and it was. we also tried holding the gas pedal to the floor. what would cause just one cylender to fill up with gas like that. it was only #7 and as soon as i pulled the plug from the hole it pour out. it had a slight miss to it which is why i did the tune up.

big pappa b- the motor is turning just not firing.
 
If you had that much gas come out you may want to check your oil. If there is enough gas that got by the rings into the oil pan it could make for a nice BOOM!!:eek:
 
are you sure you didn't get any wires crossed? might wanna double check.
 
ill deffinatly check the oil. didnt really think about it yesterday.

g mo- this is the wierd part. i put the wires on the same way i took them off. didnt start. then i printed the firing order of the computer at work and it was different. so i put the wires how the print off showed. still nothing.

its really angering me. im about to give up on it.
 
Good suggestions on timing and definately oil for fuel presence.

Most SBC's finring order is 1,8,4,3,6,5,7,2

doubtful yours is any different. I did have a motor that #1 on the cap wasn't where #1 is typically at and was told it had something to do with having the motor redone? Caused problems similar to what you are talking about until I confirmed #1's location. I am sure somebody else on here can explain how to do that better than I can. I remember turning the motor with #1 plug out until piston got to top of stroke and then seeing where the rotor was pointed.

Good luck.
 
Pull #1 Plug. Put You Finger Over The Hole. Have Someone Bump It Over Until It Blows Your Finger Off The Hole. Should Be At Tdc At That Point. Point Rotor At #1 Cyl. Remove Dist., Use A Long Flat Blade Scewdriver To Turn The Oil Pump Shaft. That Will Change The Location That The Rotor Points To.
 
Make sure you're "numbering" your cylinders correctly too.

that looks like it came from all data. good program. we used that for a while till the boss went cheap and got some mitchel program that sucks. ill tow it to work tomorow and well set the timing from square one.
 
if your vehicle didnt start and you over flooded it ,even though you pulled the plugs to dry out , they might now be fouled. try new plugs
