Dead VP44

[explosives87]

I think that my dad killed the pump in his truck and I am trying to figure out weither or not its KIA. I have check the codes and this is what I come up with 1680,1639,1389,0253,0236,0234. I cant find any info on the 1680 and the 1639.

P0234
Turbo Boost Limit Exceeded
P0236
MAP Sensor Too High Too Long
P0253
Fuel Injection Pump Fuel Valve Open Circuit
P1389
No Auto Shutdown (ASD) Relay Output Voltage At PCM

You sure that isn't 1693?

You sure that isn't 1693?

yes you have it right :doh:, I tried editing it but I couldnt and the other code is 1688 not a 1680.

That 253 code points me toward a bad IAT sensor inside the vp44 pump. All of the other codes make me think bad ecm.

Is he running any wire-tap electronics?

No he is not running any type of wire tap box. The truck will crank but not start, I can get fuel to the inlet of the VP but not throught the lines to the head.
