Damn ...... felt for sure I was feeling a 4BT conversion comming ......... missed that one ....... swing and a miss. Is there a way to measure line pressure simple enough - test port ?

Yeah - funny when you spend hours or days on easy stuff ......... good learning though as now I know how the FSS works and where it can break which suprisngly is a few sources thx guys

Think means its a metal line that connects to rubber line to return to fuel tank. Normal leak is at the fitting or more often as he mentioned in the line itself.

mwaaaaa

Also worked out how this all started. The FSS is hardwired into the terminals on the 140A circuit ......... those two connectors above the 140A fuse. So taking that out disables the FSS. Guessing thats a ppump thing Rest was bad connections.

NM. Fixed think it was a loose connection on 3 way prong going to FSS.

Dumb question - the wire that comes out of the starter on side ............ should it be 12v on crank ???

Well tested everyting out ....... all seems to work as it should ........ so not sure Only thing I can see is that if I supply 12V to the PULL wire it pulls the lever/solenoid. However at crank that wire only sees 10.5 ........ But batteries are ok and so is relay ....

NOOOOOOoooooo ::-) So its not the relay ...... it has continuity and I can hear it engage when testing. So makes me wonder --- when I pulled the 140A fuse out for alternator .... is that section of circuit protected by another fuse or something ? As the FSS draws power from the two lugs directly next to the 140A fuse .......

Did you voltage test the batteries if something has a draw on them ?

There's the fuel return line ........back of block ..... guess with air leak it could be draining back or letting air in the system. Not sure how you would pressurize to check.

Well its definately the FSS. I had the wife jump in (she was out all day yesterday) and I watched the solenoid and no movement on crank. So I pushed it up and fuel started to flow and she started to turn. Bit that threw me was it looked like I was getting fuel at lines ...... just not as much as I thought I should have been ..... So next question - how do I go about testing the RELAY...... dont think I have another one to swap in/out as different than the PCM relays I believe.

The truck had a big oil leak from tappet cover at time I bought it. I suspect a lot of the oil came from this ..... but that area and just under the vacuum pump are the worst (small leak at VP). Now there are no leaks and I clean up as I go ..... havent liked cleaning the wiring too much for risk of introducting electrical issues by accident. I have 25psi at the pump at ingition on ..... and the truck seems to crank fine and I had the starter bench tested just a few weeks back. I have the batteries on a charge now just to eliminate that ..... Im pretty sure its not the issue ....... I literally drove the truck home last night and parked it. Got up this mornining and pulled the 140A alternator fuse and blue/green sensor for the alternator ...... and noticed it wouldnt crank. Put the 140a back in and sensor still no crank. I cant think of anything else it can be since it cranks than lack of fuel. When I crack #1 I get a small feed ......... I need to have wife try and start while I watch the Fuel Shutoff Solenoid (FSS) to make sure its moving....... and then crack more lines ...... any other ideas ?

Its a 15A fuse that goes into the harness that ties back to the relay on the right hand side. I had a spare and it made no difference so I will work on that later and see what it is. I loosened the fuel filter on the AD to try and make sure pulling fuel - not a good idea I busted the O-RING loose and fuel went everywhere very quick. I then started cracking injection pump lines ..... theres fuel there ..... not sure its as much as I was expecting. I need to have the wife try and start it whilst I watch the lever ..... but in park with no key I think its all the way up (recessed).

Well replaced the 10A fuse and no different Lever on solenoid seems all the way up ... Can't push any higher

Next to Larry b relay for FSS

Ok I have another truck wont start issue. This time it cranks but won't turn over. Cracked the airdog and the lines to get any air out no difference .... was looking at wiring for the FSS seems ok but then I found this ..... Any ideas what this fuse is for ?

We'd enjoy having you guys in the area .... Then I can come bug you for tips on my truck ha .....I'll have to check out la belle sometime. You fish ? We do a bit if that here in kayaks mainly ....

Mike/guys When taking out the 140A fuse ....... you mentioned removing the blue field wire. I assume you mean the blue and green loomed wire that goes into back of alternator as a sensor/power feed ..... Measured my AC current and its like 0.02 V as var as I can tell ... so dont think an alternator issue but I have a cheap multimeter so want to be sure ... thx

I missed part of this sorry ... I really like the homosassa/wiki area about 1 hour north of st pete/tampa. Lots of kayaking/open water and quite quiet ....... semi rural ...... Can be a little hit and miss on the quality of neighbours in parts ....... and its low lying so flood would be a deal unless you payed cash and didnt insure .....(lots of people do) ...... or bought a house built up ........

Correct. It's only a 60 hp tune but with torque management it will feel like 120. It's a somewhat dirty fueling .... timing and turbos and tuning will help clear up ...

Jag is talking about this .... http://www.kentsoil.com/dodgebug1.htm

But if hes throwing a P0234 - then he wont be able to fuel to normal fuel table correct ? Meaning he needs a boost fooler so that he can extend is MAP pressure without defueling. Then the gate ....... if it was fully closed it would result in quicker spool and higher boost ............ So I still only see 2 reasons for symptoms ..... 1) his gate was open and lag from being open feels like loss of power ..... 2) His gate was closed ..... he over boosted the MAP ... triggered a P0234 and defueled. He doesn't have boost fooling ...... so thats why he triggered the code.
