Hello and thank you for your question,

As Im sure you know , in order for the engine to start and run you need good spark at the spark plugs, injector pulse, proper fuel pressure and good compression. I you are sure you have proper fuel pressure can you check the other things I have mentioned and see which one you are lacking and post back with the results and we can work from there to determine the cause.

I'll check those things but my car only has 35 K original miles on it. A tuneup shouldn't necessary until around 100 K.

I would agree and In not saying you need a tune up, we just need to check and see which signal you loosing so we can determine the cause.

It was running great and I turned it off and it would not start again.
Expert:  Ron replied 6 months ago.

I do not suspect its a compression problem with such low miles but if you can check spark, injector pulse and fuel pressure we should be able to determine what has failed.

Ok. I'll try these things and get back with you (or someone). Thanks for the information.

Post back when your ready and we can work from there.
