I've been reading up on every topic remotely close to the VP44 and fuel system for the last month. Lost my lift pump and sender unit same time which apparently blew my VP. So...100% stock 2001 6-speed...buy a new VP and decide on a FASS Titanium95. I read all the reviews but frankly the horse trailers and 5th wheels aren't a problem in these desert mountains (digression).

 

Have FSM, did install last weekend of both. Removed old filter canister and bracket (no going back, I shaved the bolts to match the others with no bracket) and removed old pump. Fuel line is just hanging. Taped and sealed each of the three connectors, then taped them together, then zip tied to the ECM harness.

 

FASS is battery and ignition fuze, so in my head, after reading all W-T and Moparman posts, I'm thinking my current lift pump has ZERO to do with the ECM. WTF? I popped a p0230 during bleeding. Ok...maybe a hold over, so I clear codes. It's late, it goes away, I shut the old lady down.

 

Start up in the morning and code comes back. Eff me. Maybe I didn't clear properly, do the drive to reset over a couple of days but...that night after work and multiple trips trying to get it to reset, CEL goes off. Sweet!

 

Nope. First start in the morning CEL stays on before Wait to Start goes off. Eff me. Start reading more from you guys about loose grounds...can't find any. Stop in to Auto zone to talk to local genius and make sure my code clear was legit, start it up for him and no CEL.

 

SERIOUSLY? Any help here would help me sleep this weekend while I'm out of town with this same truck after my code shows up again at 7am.

 

Edit: I checked the ohm tests mentioned in other posts before this fiasco with just the lift pump...but not after the repairs.

Additional info

Looks like we need an article for this now @IBMobile Gonna have to add in tags like P0230 and such and let people complain to fass till they either fix it or what not.

I understand the time and training is money. But i would think the liability for burning someone up in a wreck could dwarf that cost.

 

Wonder if AD has done this yet?

Update: I decided I had the time tonight, cold and dark as it is and that I was not going to be a wussy and wait for daylight during the weekend.

 

Funny story: Cut the harness from the pump and the connector from the ECM. Hardwired the two together. Cleared code. Ignition on, no code. Pump on half second. Bump start pump on 25 seconds. Start truck, pump is on. Ignition off, pump is off. No code. Funny right?

 

FASS is going to get some words tomorrow and reviews updated and the diesel parts powerhouses are going to get some reviews and phone calls as well.

 

I'mglad you guys exist.

 Good going getting to the bottom of this.   Did you wire the ECM to pin 86 of the rely, the relay pin that they said was turned on with the ignition switch, or straight to the fuel pump?

I put pump to ECM as if I just had an extension harness with original connector. Right now it's ghetto, but I'll redo it when I remove all of the FASS wiring and make it a little more perm.

 

EDIT: I spoke to FASS this morning. They acknowledge my issue and concerns and apologized for not doing so sooner. Too bad i didn't remember who i spoke to before. The guy i spoke to this morning says because so many of these gen dodges have ECM reference issues, my stock truck with no issues is rare (unfounded). They're actually in process of researching a resistor kit for the old connector that will fool the ECM into thinking there is a pump there. Not ideal. They also told me that the emergency breaker in the event of an accident should cut power to the ignition solving that problem. I asked them to just create the kit with the harness connector, then if ECM issues present because reference is lost, provide secondary instructions for hardwire since apparently that's been their backup solution for years.
