HELP me out please, new raptor...
 

So a few weeks ago my truck started dying randomly. Had a really dirty fuel filter so I changed it. While trying to prime the system to start it I almost had it started but noticed the stock pump sounded weak and then it went dead, couldn't hear it at all. Thinking the pump was bad, I ordered a raptor pump and installed it. Got it all hooked up, turn the key and bump it and nothing. The new pump isnt kicking on at all. Ive been working out of town and I need to get home with this truck. I really need help figuring this out. Please help me out guys. Thanks...mike

Anyone?

Do you have voltage going to it?
Is it the frrp setup or on the frame rail?

Its frrp set up, mounts were the old one went. I have not checked voltage. I will here soon. If no power what could it be?

Just noticed my wait to start light isn't coming on either

Check all your fuses and relays, make sure they are working. Bumping the starter, but not starting the engine, will make the pump run for about 25 seconds.

Checked the fuses and relays, don't really know how to tell if the relay is bad. Already bumped it, like I mentioned above, it does nothing. Tried swapping the fuel system relay with the ac relay and still nothing. No wait to start and lift pump not priming.

With the relays, the easiest way is to replace a questionable one with one that you know works. Honk the horn, if the horn works, replace the lift pump and horn relays. If the horn doesn't work, and the lift pump does, then you know which one is bad.

I'll try that. I've been reading up and it sounds like it could be a dirty sensor or the ECM. What sensors should I check, where are they, and is there a way to know if it's the ECM?

Switching relays doesn't tell me anything. With the horn relay out the horn still works. Did switch them anyways and it did nothing for the fuel pump.

Is there a fuse terminal I can just wire it to so it only turns on when the truck turns on? Is the power terminal to the fuel pump setup through the ECM so it can prime and then turn off? In other words if I do wire it to a fuse terminal will It prime automatically and shut off like its supposed to so I can start the truck and the. Run again once started? Or will I have to run it to a toggle switch and prime it manually?

Im thing to check and I bet you already have is make sure the fuel pump connection is good. Sometimes those seem like they are fully connected but they arent.

So I checked the plug on the truck that you plug the pump into and no power. Called Airdog and they seem to think its the ECM. So if I wire the pump to the fuse box and toggle switch to get running, will I damage any other parts, injection pump, etc? Also of the ECM is bad will I need to unplug the chip?

did you swap the relays?

Yes already swapped the relays. I am going to wire the pump to the fuse box and battery. Is my truck going run if the ECM is bad? Will I damage anything?

If the ECM has failed, it likely won't do anything but idle at the most. Other than that, you can try using the toggle switch.

Can't get this piece of :edit: started. Got everything hooked back up, have fuel coming from the lift pump into the injection pump, but it just cranks. Won't even try to start. Still no wait to start light either. Why the f@ck do we Like these trucks again, I've already dropped a grand in maintainence this year. I've about had it. If my ECM is bad is there a fuse I can check for it? Would I need to disconnect my chip to get it to run?

So haven't been able to run codes yet, but I'm beginning to think it might be my injection pump. Decided to crack an injection line to see if any fuel was coming out from there. Had the raptor pump going and was cranking and no fuel coming out of the injector at all. But doesn't explain why I have no wait to start light or why fuel pump power harness has no power. Anyone want to help?

These questions may sounds dumb, but we need to start from scratch.

You've checked all fuses, in the cab and under the hood?

Have you applied power directly from the battery to the pump?

Sorry don't mean to sound rude, I'm just frustrated at this point. So no I have not checked ALL fuses, just ones I thought might be related to my problems. Should I check them all or just the ones we'd think would be related to the problems? I have not applied power directly from the battery either, it's wired into a terminal on the fuse box and I'm using a toggle switch to turn it on and off. So the raptor pump is working. I'm getting fuel up to the injection pump. We decided to crack one of the injectors while cranking/trying to start and with the raptor pump on and I have no fuel coming out of the injector. As much as I've wanted to deny this, I think my injection pump might be gone. But can't figure out why no power on the stock lift pump harness and no wait to start light.

If you have air in the system it can be a pain in the a$$ sometimes to get out even if you crack lines 1,3 and 4 open while cranking.It does seem weird to not have those lights though.Have you checked blue chip diesels website they have a troubleshooting chart to check pump.They also tell you how to apply power and groud and see if the truck will start and idle.

I'm back home for a few weeks without my truck. Ill be doing lots of reading up to try and figure out a game plan for when I go back. Meanwhile the truck is sitting useless in BFE Wyoming.

Got back to Wyoming and plugged in the code reader. I got a p1694 code "no CCD message from PCM". Not sure what this means or what to do next.

No wait to start light and no power to lift pump sure sounds like ecm is bad since ecm controlls both of those. There is no way that we can test the ecm, only a dealer can. Try unhooking the batteries and let it sit for 30min with the key on to discharge the computers and see if that might reset the ecm. Thats the only idea I have other than trying to find an ecm at a junk yard.

Was you able to get fuel to the injectors?

Unhooked the batteries with the key on, I'll see what it does when I get home. So how hard is it to get to the PCM and take it off? Can I take it off to have the dealer test it? Also if info end uP needing a new PCM, can I take one off of any same generation truck?

---AutoMerged DoublePost---

I meant ECM not PCM

I know of one truck here locally that just the lift pump circuit went bad in his ecm. Found out later that it is not a real common problem but that it does happen from time to time. Sounds like what you have going on.

The computers are on the firewall behind the air filter. One of them is the ecm. I don't recall which one though. Pretty easy to get to when you remove the filter housing. You can use an ecm from any 2nd gen but I'm not sure if you would need to get it reflashed. I know 3rd+ gens a new comp has to be flashed to the truck.

I just talked to Dodge and they said the would need the whole truck to test the ecm.

Bad info....the one behind the air filter is the pcm and auto and stick ones are different plus 98-00 from 01-02 pcms. The ecm is on the side of the block below the injection pump. The ecm is where i think your problem is.

I stand corrected. But he can use an ecm from any 24v right?

It also has to be within the same year range like the pcm. If you put an 01 auto ecm on a 99 stick shift it will only turn 2000 rpm in first gear.
