Still problems

Fixed the fuel leak, replaced part of the fuel line with one that had the teflon washer (the one Shifty told me about .. thanks btw).

Doublechecked that all wires were plugged in correctly o nthe distributor cap.

Made sure rotor pointing towards no.1

Made sure no.1 piston's at TDC.



Problem is ... damn thing still won't start ...

I guess question would be ... how much can the rotor be off to cause no start at all ? I mean it is possible that while fastening the dizzy cap it may get turned a bit .. *shrugs*



This is EXACTLY like I had with my Fiat Spider a few years ago... but then I simply had the plugwires backwards .. facing from the wrong side of the car


Camaro cranks cranks cranks.. spits some gas .. now and then a burned smell when of course one gets a spark but not at the correct time


AAAAAAARRRRGGGGHHHHHHHHHHHHHHH !!!!!!!!!!!!

When you put the motor at TDC did you rotate just a bit more so that the 0° mark lined up with the balancer mark? Even if you are slightly off it should still start. Have you varified that you are getting enough fuel by checking your feed line pressure. I would also triple check your plug wires to make sure they are in the right spot. They are easy to get goofed.

Aha

Nope, I didn't rotate it a bit more to line up ... that could be the problem.

Fuel was running low so I added some (couldn't siphon it from the van though ... grrrr... long long fuel neck)


Plugwires are connected correctly ... I double checked .. marked each one of them.. 1 through 8 .. followed them from the plug to the dizzy.. marked each location o nthe dizzy too


I'll check on the lining up tomorrow, thanks

Might be 180* out on the distributor. You need to be TDC on #1 compression stroke. When it is 180* out 1 will still be TDC but #6 will be on its compression stroke. Try pulling the distributor and flipping it.

You could be 180 out, but I always make it a habbit to leave the distributor just loose enough to twist by hand and just try moving it around a bit till it starts. Some times your a tooth off and don't realize it. Once you get it up and running you can set the timing.

Dude I just did the same thing yesterday. I replaced my distributor and ended up being 180 out. Basically the best way to tell if it is 180 out is if you getting pop, pop, pop and then maybe some fire then you are probably 180 out. I pretty much do it like every 2 out of 3 times. I always **** it up. LOL!!
