Just installed 360, won\'t start in \'86 GWagon.....

I just finished installing a 360 in my buddy's '86 Gwagoneer. It cranks, but won't start.

1. I set the timing at 12degrees
2. There is spark on the #1 plug
3. Fuel enters the carb when you pump the pedal
4. This engine has good compression.

I am stumped. This thing should crank right up. I had some difficulty remebering the solenoid wires. If someone has a diagram that would be helpful. I have the starter motor on one terminal. The alternator, battery and some harness wires are all on the other terminal.

Suggestions?????

Thanks,

1. Dist.180* out?
2. Have you used starter fluid or poured gas down the throat to see if it'll pop off?
3. Not that would do much good...
4. My guess is that timing's off.

Re: Just installed 360, won\'t start in \'86 GWagon.....

I thought it was the timing also.

Originally, I set the timing statically. I put the mark on the balancer at the 12 degree location(compression stroke). Then I lined up the #1 terminal with the rotor on the distributor. After some cranking, I got out the timing light and connected it. I was getting the proper strobe at 12 degrees. Is it possible for the timing to 180'd and still get the light on the mark? I have also pulled the #1 plug to verify spark. There is spark while cranking, and if I manually turn the distributor.

Thanks,
Tom

[/ QUOTE ]Good! Just verify that this is the compression stroke!

[/ QUOTE ] From the description... this leaves only a fuel related problem or it's actually still out of time. It should pop off.

What do the plugs look like? Are they wet or dry?

Try setting the timing statically at about 6* BTDC.

Re: Just installed 360, won\'t start in \'86 GWagon.....

I do believe it is possible to be off 180* and still get the light on the mark. The TDC mark comes around on every stroke, whether it's compression or exhaust, so the spark timing would still show as 12* btdc, but it would be on the exhaust stroke and not the compression stroke. I personally prefer the 'pop the cork' method to be sure of the compression stroke.

Plugs are dry.

Fuel is definitely getting inside the carb.

I will try 180ing the distributor tomorrow.

Thanks for the tips. It has got to be the timing.

2. Then gas ain't getting into the cylinders.
3. You may be looking at two problems.
4. That's what always happens to me!

Re: Just installed 360, won\'t start in \'86 GWagon.....

What would keep fuel from getting to the cylinders?? I can definitely see fuel going to the carb(clear inline filter). I can also see fuel being squirted into the throttle plates as the pedal is depressed. I didn't leave any rags or obstructions in the intake, so what would keep the fuel from reaching the cylinders??

Everything went to gether really well. I should have expected some problems. Oh well, it is a Jeep.

Later,
Tom

I had the same problem on my CJ... my timing was 180 out... but it seems really weird the plugs are dry? do they smell like gas? I bet once the timing is right its going to fire right up. [img]images/graemlins/smirk.gif[/img]

Re: Just installed 360, won\'t start in \'86 GWagon.

Could be that the float is stuck and it's not getting enough gas to fire up??? If you mash the pedal to the floor is it squirting alot of gas? Maybe cloged up jets. A easy way to check if the carb is working is pour some gas into the the carb from a bottle and see if starts off that. If that works then you know it is not your timing. Just something else to help you narrow down the problem (you might have already tried this).....
