Engine Grounds

Where all are there engine grounds on a 86 Turbo 1 car? I took the engine out and had it out for a couple months and put it back in and tried to fire it up and I can't get a spark! I know by the thermostat there's a ground but is there one on the intake manifold to the chassie or anyother place that would cause no spark?

never mind, I found the original ground strap from the intake manifold to the fire wall and put it one and the sunofabitch fired right up. 6 months and $3400 later I have a running engine.
