No start 86 CUCV HELP!

[StephenCole]

I am having more than a little trouble starting my 1986 CUCV I drove it earlier a couple of days ago but when i was leaving a couple of hours later that same day it died before I could even leave the parking lot, it wont start at all and after making sure the glow plugs were working correctly(has been converted to a manual switch) I replaced the fuel pump, that was an entire bundle of joy itself, and got it to kick over for a second then died, now it wont even stay on at idle. I went ahead and replaced the fuel filter but when I went to prime it I could not get any fuel to come out of the line on the left side of the fuel filter mount. If I understood the directions I have read for priming it after some cranking fuel should come out of it.

Any advice on what would be keeping it from starting would be GREATLY appreciated, this has been my daily driver for more than a year so no worries about anything being seized up from sitting. Thank you all in advance!

• When you changed the fuel filter did you take the cap off the fuel tank, you will never get it primed if the fuel cap is on. It will suck air in to the filter and never start. The cap off will let the filter prime. Also check your pink wire on the IP is in place, good connection, Also if the fuel shut of switch the the pink wire goes to fails you will not get fuel to the pump to run the engine.

 

[StephenCole]

Are you not supposed to remove the pink wire while attempting to prime the filter?

I would not have even wasted my time putting a mech Lift pump back on. Toss that junk and put a stock LP for a 93 K3500 6.5TD. wire it to the power for the IP via Sol. You will be alot happier. If safety is a concern you can wire in an OPS via a T.

Could you repeat that please?

 

[StephenCole]

What are you guys talking about? What "he said crap" ?

 

[doghead]

I just undeleted post # 5, so you would understand.

Recently IGD had posted "what he said" to a bunch of threads.

They have been deleted.

Hey Stephen, are you near Waco?

 

[StephenCole]

btw, does anyone know the vlotage that should be going it the sending unit in the tank? I read 3.4v when keyed on, is this correct?

What PSI does the fuel pump at?

 

[acesneights1]

Here is the part I generally use to upgrade to an electric LP. Mods, if it's not ok to post this lionk please let me know but I don't "think" it competes with site vendors.
NAPA AUTO PARTS)

The other downside to Mech LP's is occasionally they like to take a dump and fill the crankcase with fuel...I don't think the mech ones last much longer and they certainly are a PIA. my .02

 

[acesneights1]

If you choose that route, the fittings on the LP are metric oring seat. You will (IIRC) M16x1.5 oring seat male to JIC then you can go whatever from there. I like Pushlok hose myself...

What PSI does the fuel pump at?

Around 7 is considered ideal for a DB2. Much more than 14 and your advance won't work correctly from what I was told by a rebuilder. I am running an Airdog on mine but that is way overkill and not needed.
