Where did you get these codes from ?

visit local wrecker and get need parts

Check HDLP hi beam relay in under hood relay / fuse box !

First thing is to check compression of engine and timing of the valves.

remove the plastic panel underneath the passenger side dashboard area. This panel contains built-in retaining clips and simply pops off by hand. remove three 8mm holding the blower motors assembly into the dashboard HVAC unit, use a 1/4-inch ratchet and an 8 mm socket. Remove the blower motor's electrical connector and discard the old blower motor. Install the new blower motor in the HVAC cavity and replace the 8 mm mounting nuts. Reconnect the blower motor's electrical connector and replace the plastic panel. Turn on the ignition and test the blower motor on all of the fan speed settings

Wow...that's a new one on me.

Sounds like a timing issue created a backfire of biblical proportion and blew the manifold apart.

While tearing down to replace the manifold, go ahead and take a look at timing belt.

Good luck (and I truly mean it) with this one!

Heater hose fitting? You mean the nipple that comes out of the heater core, that the hose fits onto? You have to replace the whole heater core.

That is a story or statement Do you have a question with details,test results or something to work with? Have to do testing for a no start & let us know how that is going

In the fuel tank

outside under the fuse block

po300=multiple cylinder misfire,,is that the only on code,

Rear corner area..normally squeeze it in a little and it will fall out

Could be two issues. First could be the cruise control. I would try disconnecting the link to the throttle from the cruise and retest. If there is still an issue then your problem can be a throttle position sensor or the onboard computer. This is a hard one to diagnose without seeing the vehicle itself.

-Possibly broken plug wire. Check it with ohm meter. Good luck Mai

What are the stated reasons for the codes? That many codes smell like something's messing with you computer

In your owners manual

My guess is the fuel tank sender unit has come adrift inside the tank somehow. Run the car to a very low tank level, locate the tank sender unit release it to access it and see if that gives you any clues. Please remember you are dealing with gasoline and all precautions should be taken. If you are not sure how to do it get a knowledgeable neighbour or good DIY tech to help. I'm pretty sure if you fix the sender problem it will stop the erratic message.
