Ran fine before I turned it off. It shows the amp and temperature on the gauges.

Hi,

It could be a few things. If the crankshaft position sensor failed, it will cause a no spark condition. Take a look at pic 1. It shows the sensor I mentioned. However, before we jump the gun and start replacing parts, we need to do a couple things.

First, I need you to pull diagnostic trouble codes. You can do it without a scanner. All that is needed is a short jumper wire or even a paper clip. Here is a link that explains how it is done:

If a code shows it could be the sensor, pic two shows the resistance you should find when checking it.

Now, this vehicle also has an ignition module, AKA (DIC) digit ignition control. This is what the coils are mounted on. I may need to have you remove it and have it checked at a parts store if needed. I will explain that at a later point if needed.

Here are a few links you may find helpful when checking the sensor (if needed):

Also, here are a couple links you may find of interest dealing with the crankshaft position sensor:

Start with trying to retrieve codes. Let me know what you find or if you have questions.

Take care,
Joe
