My car's engine shut off last weekend while driving and wouldn’t start back up. Since then, it’ll start sometimes, and other times won’t. All electrical systems still work, and the engine will turn with the key in the ignition but won’t start back up. Any tips? Right now, I think it may be a fuel pump.

Hi,

What you described can be caused by a couple of different things. First, when it won't start, see if it will using starting fluid. If it does and then stalls, we will know it if fuel related. If there is no change, then it is likely ignition related. In that case, I need you to check for spark to the plugs. Here is a link that shows how it's done:

If there is no spark, my first suspect is the crank angle sensor in the distributor. See pic below for location.

Let me know if you are comfortable doing this and the results.

Take care,

Joe

Joe,

I tried your suggestion with the starter fluid and had no luck. After checking to see if the plugs were sparking at the distributor. I think you re right about the issue being with the distributor, as the spark plugs are only 3ish months old. You re a legend, now I can start to get her road worthy again. Thanks a lot mate!

You are very welcome. Let me know what you find or if there is anything I can do to help.

Take care,

Joe

PS: Great car. I once had a 240Z. I hung 6-weber side draft carbs on it. I had a lot of fun in that car. Glad I'm still alive. LOL
