52
52

22
29
33

Running test codes:

What the H*** is wrong with my truck?

Distributor
moduale on side of distributor
plugs
wires
cap
rotor
coil
sea foamed it

please help!

 

I would clear out the codes and start from scratch, and also check the fuel pressure.

 

Thanks sean for helpin out.

How exactly do you clear the codes?
My engine light (the red one) is always on in my truck.
also check fuel pressure on the rail on top of engine?

thanks man! hope to hear back soon from you!

 

The "engine" light is an idiot light that will come on for low oil pressure, high water temperature, or a charging fault. Yes there's a port on the fuel rail to check pressure. Easiest way to clear codes is to disconnect the battery for a few minutes.

 

Okay that makes sense. My truck has mechanical gauges for water temp, oil pressure and voltage gauge. So that takes care of that light. As far as my check engine light goes, it has never been on since i've owned the truck. My truck runs perfect other then it won't rev past 3500 rpms. I'm going to go check what my fuel pressure is right now.

What should the pressure be around?


Thanks, Colby
