Getting a situation of intermittent hot start problems. These are no-start conditions. I have not experienced any problems once the engine is running.

Note: fuel pump relay was replaced 6 months ago to fix a complete no-start problem. I am assuming (always dangerous) that my issue is ignition related but haven't had time to check with spark tester or timing light.

Here is what has happened
1. Noticed trouble with hot start after sitting say 5 minutes--takes 2-3 tries or a wait of 5 minutes for a succesful start. No start consists of crank with either no result, or slight "chuffing" with no run at the end. Not experienced after sitting for several hours.

Consulted FAQ ordered CPS and ignition module--installed new ignition module

2. OK for a couple of days now I can get the no-start after sitting for 8 hours while at work but starts first time after overnight. After short errands I can either get the no-start or an OK start.

Question for the experts--what should be the next step?

New Radio suppression relay?
Install the new crank position sensor?
Change engine coolant sensor?
Try another fuel pump relay?

I have two 240s sitting around that I can swap parts with if needed.
