Hello Customer (name blocked for privacy) and welcome to Just answer.com, Super mechanic here. About your Lumina van.

Yes, I would susspect that the ignition module went bad, but you want to make sure that the distributor is turning when the engine is cranked. If it is, I would replace the module. You can pick one up for about $26 at Autozone.

That would be the timing chain. That is what turns the camshaft which in turn turns the distributor.

Here are the instructions for that. You might want to jack the engine up to give you more room, thanks

This procedure requires the use of a crankshaft sprocket removal tool, and a sprocket installation tool.

  1. Bring the engine to TDC on #1 cylinder

  2. Disconnect the negative battery cable.

  3. Drain and recycle the engine coolant.

  4. Remove the right front tire and wheel.

  5. Remove the engine front cover, as outlined in this section.

Align the timing marks on the cam and crank sprockets. Use the alignment marks on the damper stamping or the cast alignment marks on the cylinder and case for reference.

  1. Place the #1 piston at top dead center with the marks on the camshaft and crankshaft sprockets aligned.

  2. Unfasten the camshaft sprocket bolt, then remove the camshaft sprocket and chain.

Lock the crankshaft to prevent it from turning, by freezing it with a prybar at the flywheel before attempting to remove the crank sprocket.

  1. Remove the crankshaft sprocket using a suitable sprocket removal tool.

To install:

  1. Install the crankshaft sprocket with a suitable tool. Lubricate the sprocket thrust surface.

  2. Hold the camshaft sprocket with the chain hanging down and around the crank sprocket.

  3. Align the dowel in the camshaft with the dowel hole in the camshaft sprocket.

  4. Draw the camshaft sprocket onto the camshaft using the mounting bolts. Tighten to the specifications shown in the accompanying figure. Install the crank bolt.

  5. Lubricate the timing chain with engine oil.

  6. Unlock the flywheel and using a socket and breaker bar, rotate the engine (crankshaft) twice. Make sure the timing marks line up again at TDC.

  7. Install the engine front cover, using the directions given earlier in this section, and complete the installation procedure.

  8. Connect the negative battery cable.

I would say that a fair price at an independent shop would be around $450 or less. That would be for the gears and chain and gaskets. You might run into some other items like, coolant and oil change and maybe a belt or tesioner.
