P0230- Stuttering while driving

6312 Views 9 Replies 5 Participants Last post by  Junkman
Well my truck started running weird this evening, I still had 17psi on my edge but when I parked the truck it dropped to nothing. I've had issues with poor grounds at the battery in the past so I'm going to check that first, but I have also read about issues with airdog/raptor relays. My raptor has been on for years, I honestly can't remember how long, maybe 5 years? Never had any issues with it.
Really I'm just curious if I check it all out in the morning and it turns out ot be a bad relay, are the raptor relays just a universal relay or do I need to order one specifically for it from pureflow? If so that would be a huge pain in my .
This just sucks because it just got real cold up here and my dad is borrowing my '05 while he's waiting for his '06 to get delivered, so this is my only vehicle right now.

Double check the fuel pressure with a mechanical gauge to rule out the electric sender is possibly having trouble on the Edge monitor.

Then as for the P0230 that error code basically states the current flow for the lift pump circuit is too high (lift pump rotor locked) or too low (lift pump circuit open / disconnected). Kind of mixed bag on that code some people get them from aftermarket fuel systems and others don't.

You might double check and see if you can fit a normal 30A aux relay in the socket.

Well a little bit of an update on it.
Seems to me it may be a clogged filter, or maybe clogged suction screen on the raptor itself. I had a 1/4 of a tank yesterday evening so I stopped at a gas station I usually don't stop at and put an extra $20 worth in. About 10 minutes later is when this started happening.
This morning I checked and rechecked all the connections that I could. My negative terminal clamps are pretty nasty so I'm going to replace those today.

What seems strange to me though is the fact that after I redid all the obvious grounds and connections for the lift pump it ran fine with a steady 18psi on the Edge (sorry I just don't have access to a mechanical gauge right now). Yet when I pulled out of the driveway to head to work and gave it some throttle my psi dropped steadily to 0 and the truck started stuttering. I shut it off for 5 seconds and restarted it, the pressure was back up to 17/18 which is what it usually runs at and was fine with light throttle.
I verified that the pump is running when I got back to my house (I just turned around instead of limping it to work), and sure enough if I bump start the engine the pump runs for its usual however many seconds.
The second time I took off to head to work I gave the truck very light throttle the whole way, it's only 1.1 miles down the road, and as soon as I turned into the driveway at work (which is slightly up hill) the pressure dropped as soon as I got on the throttle a little more.

So I guess my question is: If the filter is plugged and the pump is working harder to push fuel past the clogged filter would it throw this code? It makes sense it would in my mind because of the fact that the fuel flow is increasing to the filter yet flow out of the filter is still the same so it would take a higher draw at the pump hence the code.
I can clear the code on the edge before starting the truck and when I turn it on the code does not come back on as it is idling yet if I give it too much throttle and lose pressure the code comes back.

Any ideas? I am stumped. I'm going to change out the filter today and probably buy new grounds and clean the terminals. I am also going to try to look for a relay just in case that is the issue.

Just really frustrating, I've been really happy with how this truck runs now, in fact literally 5 minutes before this happened I was thinking to myself how much more I like this truck than my '05. Then this happened and I remembered why I bought my '05...

If it's a simole 30 amp relay, try to get a Bosch. Even Cole Hersey relays are Chinese & prone to failure.

This is one of the few reasons I didn't do the Raptor.

I would highly suggest you get a remote mount filter bas and a spin on pre-filter/water separator and hook it up before the Raptor. Loss of pressure is a sign of fuel restriction. So its time to get busy and drop the fuel tank and see what your pickup tube looks like and/or check the screen on the Raptor (if one is installed?).
Well I was fortunate enough to be able to pull the truck into the shop at work. I changed the fuel filter, swapped out my grounds on the batteries and covered them with spray on connection protector and also blew out the fuel lines with an air hose. I've seen algae clots get clumped up in there.
The filter still looked fine and I didn't see anything too nasty come out of there. Drove home fine without any hitch, I guess we'll just have to see how this works out.
I did get another relay just in case.

Well I guess I will have to end up dropping the tank, must have sucked something up into the drawstraw or that connection after it. I blew out the other lines and ended up replacing the relay and am still having issues with it. Not as frequent as before but I am still having problems with it.
I need to double check the wiring for the raptor since this thing has been on there for so long.

And the extra filter is something I have been thinking about but honestly I think this is something in the tank or the actual pump going bad, I pulled both lines off the raptor and nothing was lodged in there and after blowing out both lines I don't seem to have anything stuck before or immediately after.

How much of a job is it to pull the pump itself apart and what actually goes bad in there? If I can just pull that bottom cover off and see what makes it tick I can be certain nothing is stuck in there.

I was really hoping this P0230 code would be more specific and lead me right to a problem rather than being such an all encompassing issue.

Well I pulled everything apart, cleaned and checked it twice. Replaced the relay for the OEM fuel system and the relay for the raptor.
Started stuttering more frequently this afternoon and on the way home I lost all pressure and can't hear the pump turn like it usually does when I turn the key.
Guess it was just the raptor taking a dump, so looks like I'm due for a new fuel pump.
I'll have to dig out my receipts and see if I can get it warrantied, if not is it really worth it to spend the extra dough on a FASS? I was really trying to save some money up for an exhaust brake on my '05.. :S:

i really havent heard good stuff about raptor pumps, i would go with the fass

If pressure consistently drops going up hill or stopping or turning, you have a pick up that is near the top of the fuel level. Since this is new, you may have developed a leak OE crack in the pick up.

Clogging filters by stuff growing can be solved by Startron. The have a diesel formula that works wonderfully - better than anything else I've seen.

Some have made battery cables from welding cable. There is no good reason to drive with questionable cables or connections.
