Heys guys I have been chasing this problem for a couple of days and here are some of the details.
I have a 1991 volvo 240 NA with LH2.4 and I am having the occasional no start condition.
When I start out on a typical trip the engine is cold and fires right up within a second or so.
However when the engine is warm say after 30 minutes of highway driving and I park the car for a 5 to 10 minutes the following can happen;
Fires right up as if it was cold.
Takes few seconds of cranking but eventually fires up.
And finally will not start at all.
I have encountered the no start condition twice.
The first time I waiting about an hour or so and it fired right up.
the second time I was trying to induce the no start condition and I finally was able to reproduce the no start condition in my garage.
After the first no start condition I installed a new CPS on the car after the first no start incident.
These are some of the things I checked.
1) I have a good solid spark
2) I hear my fuel pumps key on as well as I have confirmed a fuel rail pressure of about 40 psi.
3) After the no start condition occurs it appears the plugs are clean and dry.
4) The injectors do not appear to be pulsing.
Eventually enough time had passed where the car did fire up but I wasn't because of anything I had down while troubleshooting.
When I was trouble shooting I was able to swap out the ICM and ECM with non matching PN components. (didn't make a difference however when I was able to get the car to run it would run with either)
Not really sure what else to check but I am open to suggestions.
Thanks in Advance
