Was driving down the road and it just went dead. It's getting gas and fire but will not crank.

Does the check engine light go out as you crank the engine? If not, if it stays on, the computer isn't getting a good crankshaft position sensor signal. Replace the sensor or fix the wiring harness. Bad sensor is fairly common

Sounds like a crank sensor issue.

tune it up n check the timing belt

you need to check and make sure its getting fuel, sounds to me like the fuel pump went out on you. could also be a firing problem, Check your distributor cap and rotor button. Be sure they aren't burnt. and lastly this is the worst case scenario, Timing belt/chain broke/jumped time in that case it is a very time consuming job and should be checked/repaired by a professional.

sounds like the timing is off. check the firing order to be sure your plug wires are on the correct positions on the coil packs. if that checks out, possibly a timing chain may need replaced. i hope this helps

You'll have to figureout if it is a fuel or ignition problem.Is the check enginelight on ?

Does it have spark & fuel pressure ? Do you know how to check for these ?

From your description it seems the dynamo has shorted. Get that checked first.

What is the fuel pressure?

try checking the timing belt.
