installed westach fuel pressure guage on the shrader valve this evening and am only seeing 3 psi at idle and 0 at full throttle. what do i need?

 

1. Add a fuel pressure gauge, this will eliminate bummer surprises like this one.

2. An aftermarket fuel kit, FASS etc.

3. If you want to go less $, contact Eric at Vulcan Performance about one of his lift pump relocation kits.

4. Have you checked your engine codes yet? Turn key on-off-on-off-on and look at your odometer.

Is the truck still running fine? As good as before the fuel press gauge? Your saying that there is something going on with the gauge and not with you truck/fuel pump right?

 

yea its running fine, so hopefully its the guage, i did the key trick and got p 1693 & p 0236

 

Doesn't sound like the gauge is bad - you've got a bad code that confirms that the gauge is working.

0236 is a mistiming event in the injection pump. It can be set at low pressures as you've described - it may mean that your VP-44 isn't getting enough fuel and is nearing failure. Or it may mean that your VP-44 isn't getting enough fuel and has already failed. Check your lift pump, clear up the fuel delivery issue (over 12 psi idle, at least), reset the codes, drive the vehicle, check for codes again. If you get 0236 again - your injection pump needs replacement. It's not cheap.
