Welcome. Be A little more specific. What do you want to know? What are you working on and trying to accomplish.

Does Wait to start light come on every time you turn the key to start? Make sure the lift pump is getting power from the ECM before condemning it. If getting power when you bump the starter, what is lift pump pressure at the VP or filter. If not, or very low pressure it could have taken out the VP.
Pull codes with a scan tool, not the key?

 

[bigfish95971]

You must pull codes pull codes wiht a scan tool. many parts stoes and otherswill d it for free, or you can buy cheap one for 30-100 dollars. CEL definitely should have thrown codes.

 

[bigfish95971]

You have to get or use a code reader. 1693 only says there is other codes, not what any mean.Check engine light will stay on with WTS light as long as the grid heaters ae drawing down the system voltage, and shut off. Itmay also stay or come on if the ECM is bad. No or late WTS light means bad ECM. Most parts stores will pull codes for you or let you use a reader in the parking lot. You can buy one for as low as 30 bucks. Do it.

When I put in the in tank conversion about 400k miles ago I have had no problems. First 350k was 2 of stock pump.

 

[bigfish95971]

If dodge still has he complete kit I think it was about $450. Google lists a few options in aftermarket complete conversion kits for about $950. Ebay has a bunch of cheap crap of just canisters and pumps, but I have no idea if any are good and most are not the full kits needed

 

[bigfish95971]

Nobody is asking you to change. OP ask for options. He is right on block pumps often last only 70K, Fass and Airdog a bit more vut still fail. I can not remember omre than one or two in tank pumps failing on ours.

Key trick or speedo button do not chow ECM/PCM codes. There is a cluster check that can be done, I forget how.

Open and read. pay attention to Afterburn about grounds. Check all harness plug sand grounds on fender, firewall and negative on battery. Check all hanress plug pins on ECM VP PCM and others for corrosion on any individual pin or socket hole.

380 and 382 are due to the deleted grid heaters.

 

[bigfish95971]

I still do not see what we are working on, Year, Model, 4x4, trani, miles, options, mods.etc.

 

[bigfish95971]

The key trick will work on some 01 sometimes, do not depend on it, uses scan tool. Yours is early one so I do not know.

Repost symptons, anything new or forgot, Details when where and how?

 

[bigfish95971]

12.3v? Are your batteries dead? If not you may have bad or corroded connecctins or wires somewhere. If battery voltage it should be a bout 12.6v.

 

[bigfish95971]

What is/was battery voltage at each battery disconnected. Should be 12.6 and not go down just sitting, regardless of temps.
