vp44 shutoff solinoid?

So the truck cranks and cranks but dosent fire. lift pump runs like it should a couple of seconds with the key on and tenty something after bumping the starter. got fuel to the injector pump. Key trick gave me a p1693 and nothing else. Plugged it the scanner and found a lift pump code. p0230 ? while looking at live data the fuel shutoff solinoid is not turning on. Once in a while it goes on for a second and back to off. Checked wiring and connections and found nothing abnormal. Is the shutoff a sevicable part or is the pump junk or am I looking in the wrong spot? As always any help is greatly appreciated! Thanks, Kyle

No fuel shut off solenoid on the VP$$, the VP$$ has a relay (called Fuel Pump) in the power center under the hood. I believe that the power to closed that relay coms from the ECM, just like the power for the Lift Pump. There are several with the same part number and are interchangeable.

Questions:

What happen just prior to this problem starting? For example, was any maintenance or were any modifications done, etc.?

What is the fuel pressure at the VP44 fuel inlet when you bump the starter to activate the lift pump?

Have you verified the 14ga red/light green wire at the VP44 connector has 12v power when the ignition key is turned on?

Regards,

Haven't done anything to the truck for awhile other than oil, filter, and fuel filters. haven't had the edge hooked up in over a year. Will try to check power and fuel psi this week. Thanks, Kyle

Finally got some days off and gonna see ifI can get it runnin'. Took the edge off cause it needed to have a smog check done. I was the first of anyone I knew to have it done and wanted to pass. I had heard that the truck would fail with a programer. Loved it when it was on there and will hook back up.

Im having a similer issue and could use some help. had ECM replaced almost a year ago, no problems.....till now. every once and a while the truck will crank and not fire, even after multiple times cycling the key. i can hear the humm of the lift pump and i wait for the Wait to Start lamp to go off before cranking. it never fails that AFTER i put a call into AAA, it'll fire right up and run fine (smoothe, no smoke, no extra noisem, etc.). Then it'll start fine for a few weeks, then do it again. Any suggestions? I wanna have an idea when i take it to the shop.

Lift pump directly controlled by the ECM. (No relays)



As for the VP44 its power is controlled by the ECM and Fuel Pump relay in the PDC.

if it's a simple relay, i may just cough up the 10$, replace it and if i never have the problem then great.
