Evan G Posted November 22, 2011 Report Share Posted November 22, 2011 Too much or too little pressure? Have you got a manual gauge on it? Quote Link to comment Share on other sites More sharing options...
styler Posted November 22, 2011 Report Share Posted November 22, 2011 The pump has an inbuilt bypass when pressure gets too high, can get jammed if pump is old. Quote Link to comment Share on other sites More sharing options...

ke70dave Posted November 23, 2011 Report Share Posted November 23, 2011 is the guage shorting out? if a sensor/guage throws up odd readings, first step....look into sensor/failures. Quote Link to comment Share on other sites More sharing options...

JDM KE70 Posted November 23, 2011 Author Report Share Posted November 23, 2011 is the oil pump valve getting stuck the normal fault. has this happened to you? Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted November 23, 2011 Report Share Posted November 23, 2011 If the gauge gets shorted out I believe it goes to max reading, so it could also be in the wiring anywhere from the gauge to the sender. Hopefully a new sender unit sorted it out. I can't see the pump delivering more than 60 or 70psi a the most, and that is when cold. Quote Link to comment Share on other sites More sharing options...
