replaced fuel pump 3 months ago. One month ago would not start. Exchanged the ALL and DEFROSTER main relays and ran fine.
last week stopped running, towed in. Checked all mechanical, compression, spark etc. No fuel again. Checked relay and no voltage on output.
New relay arrived and installed, ran fine, test drove fine. Three miles later no fuel again. Not sure how to re-test the relay as there are 2 wires giving 12V but I beieve it should be 3 wires. Towed in again. Test shows that there are two proper grounds at the pump connection…can not prove intermittent.
Can anyone give me the test instructions fo the relay to assure it is functioning, also if it died does anyone know what would have caused a new relay to fail in 3 miles?
If this is a ground problem, where would the bad ground be found?
The anti start switch in the shift column is particular about its position as start up. However I dont think the fuel pump relay should be a problem from that.
there are no trouble codes.
I have a 1990 Mazda mpv v6 3.0L RWD with 220,000 miles on it, whenever I start the car it makes a loud screeching sound, it sounds like its metal on metal. It only will make the sound in park and neutral though. When I shift into gear everything sounds normal. Does anyone have any suggestions as to what this could be? Oh and the transmission has about 150,000 miles on it.
But, no fuel is getting to the fuel injectors. Fuel injectors test ok, as well. Computer checks good Distributer has been changed, New coil, new ignition wires, New ignition switch.
