Car Problems

What a week, I am going to list everything I have done so far to our 1998 Mazda MPV to see if I can get any help out there.  I am sure, together, we can find the answer:

Here is a time line of what has happened and the results:

Prior to beginning I had a check engine light on with the following 4 codes: 1x catalytic converter code, 3x misfire codes (cylinder #4)

So, Friday: I changed:

1. air filter
2. oil
3. oil filter
4. rotated tires
5. cleaned brakes

Car still ran smooth. Then I did the following almost at the same time:

1. added sea foam (fuel injector cleaner)
2. changed the spark plugs 

After this the car ran very bad. We drove it for hours to use up all the gas and work out the "gunk" that may have been "cleaned" by the sea foam.  To no avail, finally Saturday night

1. Replaced the fuel filter

Ran very smooth, test drove vehicle approx 5 miles, smooth driving, plenty of power, shifts just fine, idles fine.

Sunday morning: would not start. So, I checked:

1. spark plugs, they were dry (no fuel there)
2. spark plugs did have spark
3. fuel line after fuel filter before injectors, lots of fuel coming through when cranking engine
4. fuel line return, after injectors, fuel flowing back to tank when cranking engine

Finally during troubleshooting the engine started.  BUT it wasn't anything we did while troubleshooting.

Monday: Next morning, won't start (cranks fine, seems like no fuel), by noon, it started

I checked the EGI relay, switched A/C compressor relay and EGI, no change, when I put them back, the A/C relay didn't work, purchased another A/C relay, A/C compressor works just fine now.  I feel like I need to find out why the A/C relay stopped working, any suggestions?

A friend, Mark (Thanks Mark), stopped by.  by this time the vehicle was running.  He:

•  suggested I clean the battery terminals 
• checked the wires going to the injectors (no apparent damage)
• "listened" to each injector, sounded fine

Tuesday: Won't start (cranks fine, seems like no fuel), by 10 am it started just fine (didn't do anything to vehicle, just tried to start it and it started.)

Tuesday evening:

1. cleaned battery terminals
2. drove to AutoZone, had battery checked for charge, 100%
3. rechecked check engine light, now only 2 codes: P0304 (I believe) misfire cylinder 4 and the second code was the coolant temp sensor - (not surprising, as i found the red wire had broken off during an inspection of the engine)
4. Look toward the center of the picture, here is the zoomed in view
   
   

Now Wednesday morning:  Won't start, cranks fine.

I am posting this blog to see if I can get any advice out there.

Has anyone heard of a problem like this?  Please post

Won't start in the morning, does start in the afternoon.  Not doing anything to the vehicle.

Any advice/suggestions will be greatly appreciated.

Thanks in advance for your assistance,

Clint
