I am getting code P0230 Fuel Pump Primary Circuit Malfunction. My fuel pump is brand new and my gas gauge will not work now I am guessing because of this code. Another issue that I am having is I replaced the switch box under my dash and now my car won't even turn over. Any advice with the culprit would be greatly appreciated.

Did you replace the pump and hat assembly or just the pump? Is there any chance you may have crossed some wires if you only replaced the pump?

Can you reinstall the old switch box (I assume you're talking about the fuse box) to see if the car turns over again?

Replaced the hat and pump. Not talking about fuse box talking about the box under steering column that controls the starting of car with key switch.

Po230.

Ccrm. Ford pin point test X150.

Have you checked all your fuses?

Has po231 or 232 shown along with po230? This is for continuous code po230,,

Points more to wiggle test on circuit


Ford service manual.

Powertrain/emissions diagnostic section is what has all the codes and repair for them.

Chilton library hosts this book.

The advantage with manual.

It will tell you what the pcm seen to trigger code.

Than tell what circuit to check.

How to check the circuit,what machine to use and what settings

Each test has an intro,,

Here it gives wiring diagram to show pins your testing

Codes are mostly electrical issues,,the item is rare to be bad ,,most people just throw parts at it.

No,,I enjoy code chasing,,

Having the book makes it easier,,but book is written for someone who went to ford's class,,

Class is also in Chilton library free.
I changed the switch module box and not it won't turn over however everything in car comes on and I can jump starter this is a manual transmission also. When it starts after jumping starter it cuts off like there's a fuel issue.

More history may help.

You said ccrm had been changed,, sounds like you have had some type of issues before working on it,,

Is everything connected at throttle body,,I know mine won't run if air tube is off that has maf in it

Yes it's been changed by me. Everything is connected it just won't turn over someone said my neutral safety switch could be messed up.
