Gas release in ford tempo 1986


There isn't one. You have to pull the fuel pump fuse or relay. Start the car and let it run out of gas to relieve the pressure. All I do is loosen the nut at the fuel rail or fuel filter with a cloth/rag around it to keep it from spraying on me.

1986 nissan truck starts fine runs a min. then stops.Driving it you have to keep pumping gas for it to keep running


Hook up a fuel pressure tester start and let run until dies and check pressure if plenty of pre.ssure If this is a carberated engine tune your air and fuel mixture jets located in front bottom of the carb.., hook up vacuum and set to your hightest reading and then set your idle screw to prefered idle which is around 8 RPM If this is a injected system hook up a fuel pressure guage and start engine and let it run until it stops keep an eye on pressure to see if the pressure drops or stops if so replace fuel ****

1986 Ford LTD 5.0 engine; Failed HC emissions. Did tune up, new air filter,oil change. 2 bottles of HEAT and 1 bottle of Guarantee to pass. HC came back 2.90 passing is 2.50. What could it be.


Heat is pretty much methanol...it will counteract the effects of the other additive you used. Run that stuff out of there and try using 3oz of acetone per 10 gals of fuel and possibly adding a couple of degrees more advance to the timing. If you know anyone with a gas analyzer, perhaps they can help you get it set up.
