High fuel pressure

docertabum · #1 01-11-2007, 10:26

Guys, I need your help. I tried to solve it by myself, but without result. I can't crank up the engine. I found out, there is a higher pressure of fuel then stated in manual. The sparking plugs are totaly floated with gas... Without even litte sign "ignition". I hope you understand

Do you have any suggestions, pleeeese? I have FJ20E engine. Btw. all that started when I got home and tried to park my cars. But the engine sudednly stopped. I found out my powersteering pump was jammed as well and of cource the belt was burnt in one place. Could there be any connection between those two "events"?

the bearings are probly siezed on your power steering pump, nothing to do with your other problem, which will be your fuel pressure regulator, located near the fuel rail, they are sperate on the fj20e, i have about 3 spare, if you need one let me know.

yes you can put a gauge in the fuel line.

I did it... the pressure of fuel was 2.7-2.8kPa in idle situation... normally it should be somewhere around 2kPa I think....

not sure about kpa, but it should be around 37 to 45lbs.

For the FJ engine fuel pressure check, the s12 manual states:
at idle approx 206 kPa (or 2.06 bar or 2.1 kg/cm2 or 30 psi)
the moment throttle pedal is fully depressed approx 255 kPa (or 2.55 bar or 2.6 kg/cm2 or 37 psi).
Hope that gives you enough different pressures to go for

....LOL....

Ian.

what-a-fancy regulator...

It would be coolest thing in that car.... except orange chassis with black stripes

)...

btw. guys, who have FJ20E engine... what did you tune in it?

warning - stupid question: I have to go to check CO emission. I pray everythign will be ok, however I'd like to know how could it be adjusted in S12 if needed?
