I have a 2002 Dakota with a 4.7. It has 235000 miles and the other day I shut it off and 5 minutes later when I went to start it, and ran bad. I am now getting the following codes. P0300,P3001,P0302,P0351,P0354, P0355,P0356,P0358. Any ideas. I was looking for a list of what the codes mean but could not fingd one.

Bad ignition module heating up and failing.

Remove the black connector to pcm . Check for corrosion pins . Then inspect the plug end for corrosion. I found moisture seep by the weather pack seal and wire on older vehicles.

you should chek ur fuel pressure and pump if pump is drsggimg its going topop switch lack of powerits because not enought pressure and gas mileage pretty bad fuel injectors will openlonger to compensate low pressure

remove dog house locate test port and install guage should be 45-60 psi

You have two pumps,I guess you know that ,if you already did one. Did you check fuel pressure at the rail and check out the electronic pressure regulator? What codes are coming up and do they stay set?

Bad switch #2

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.
