I just went through this on my 98 safari. P0420 scanned catylist deficiency. I changed my fuel filter. Took about 30 mins. lost minamal fuel amounts. Part cost: $7.00. This fixed mine.Didn't need to jack it up. You can if need be. Takes 2 wrenches, 1 small socket, filter, and drip pan. All pretty much self explanitory, once you find the filter. Nothing will blow up, just be careful, and don't smoke anywhere near it. As for clearing the code...I don't know. I have a scanner that I used. As for the P452 code. Don't know anything about that. Hope this helps.

You may need a mechanic. At least a shop manual.
The catalytic converter code means the computer does not think the cat is working right based on input from the O2 sensors. That data would need to be checked out and verified along with a temp scan of the cat itself.
The other two codes are saying the signal from the pressure sensor is too high and too low. The computer measures pressure inside the gas tank to make sure it vents correctly. The pressure sensor could be faulty, or it could be something else in the venting system.
You may just need to have the code cleared. If you have a reader that will erase or reset dtc codes thats all it will take. some codes will reset just by doing a few drive cycles but other codes need to be cleared. There are a lot of places that will read or reset the codes for free if you don;t have a reader. That would also give you a chance to see if there are other problems such as brake pad sensors that are also part of the problem.
Diagnostic Test Code (DTC) C0265 is a POWER circuit code for the EBCM/Pump Motor Relay, not a ground code. This DTC sets when the voltage (B+) is too low at the EBCM when the solenoids and pump motor are commanded OFF. The voltage is supposed to be pulled low when the circuit is commanded ON. A ground problem with the EBCM is most likely to cause a failure of the EBCM to communicate with a scan tool. However, it doesn't hurt anything to check the ground. The main ground for the EBCM (G106) is located on the left rear of the engine near the knock sensor.
you need to find out if there is any code stored in the vehicle's computer. ask your mechanic to hook up the scan tool to it.
if he does not have a scan tool then he should not working on your vehicle.
you can go to ant parts store to have it check for code for free. this is the first step you should do
P0301 is a DTC code that indicates a misfire to cylinder one. It could be a bad spark plug, spark plug wire, rotor and cap, a dirty fuel injector, or the worst a bad head gasket. Cylinder 1 is the first cylinder on the drivers side, towards the front. Start with the simple and check the spark plug wire and add fuel injector cleaner to the gas tank. Good luck and hope this helps you get you van running 100% soon. If that did not help, then your going to have to do a tune up by replacing the spark plugs, wires and rotor and cap. You can get all the parts you need at Auto Zone and they can give you the step by step to get the job done with common tools in under 2 hours of your time. Keep me posted, be glad to know you got your van running 100% again soon.
DO'ES THE VAN TURN OVER ? DO'ES THE VAN HAVE THE FUEL PUMP RUN LONG ENOUGH TO BUILD FUEL PRESSURE?IF YOUR FUEL PUMP AND STARTER ARE WORKING THEN CHECK FOR FIRE TO THE PLUGS. YOU MAY NEED TO GET THE CODES READ TO FIND THE PROBLEM IF YOU HAVE FUEL AND FIRE.ONCE YOU GET THE STORED CODES,REPLACE THE SENDER THAT CAUSED THE CODE OR REPAIR THE WIREING TO IT.
My 1997 safari was doing the same. After being shut off for a short period of time it started as if it was flooded. If I put the accelerator to the floor it would fire up. As well, I had no engine codes to report. I replaced the fuel pressure regulator and everything is great. It was leaking fuel into the engine causing it to act flooded when starting. Once started, the computer system made adjustments for the leaking fuel so the engine ran fine. If you turn the van off and immediately try to start it, it should fire up. (don't give it time to leak extra fuel into the engine)
