Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Is the engine cranking over with the starter when this occurs or is the starter not engaging?

Was the ignition module ever replaced (attached to the distributor)?

Customer: replied 1 year ago.
No
Expert:  Pete replied 1 year ago.

O.k.,the biggest issue on this model for a no start no spark issue and can be intermittent at first is the fault with the ignition control module located on the side of the distributor.

Test each wire for 0 voltage at this module with the key off.If this is o.k. turn on the key and test for around 12 volts at the red wire with light green stripe. and o volts at the red wire with light blue stripe.If these are o.k. and if your starter is engaging but you have no spark and no start the ignition module needs replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
