How do i replace fuel pump 95 taurus 3.0 6v ohc

Run tests. Fuel pressure correct? Spark at plugs when cranking? Fuel injector pulse working? Compression test?

I would check the EEC relay, and the fuel pump relay too. But it sounds like the ignition module is loosing power, or the pump is not getting power after the engine starts.
The computer must see oil pressure or RPM to power the pump relay after the engine starts.

Do the cooling fans work ?

would need to check out all sensors with a scope when it doesnt start to locate the fault

I owned a 95 Taurus for several years and done my own maint. I never heard of an external oil pump. The pump is in the oil pan and runs off the cam shaft. To replace it you have to pull the oil pan. After that it is fairly easy. Take out the bolts and it will come out. There are no springs to worry about.If you were talking about some other pump let me know.

Hello , fuel pump relay location is in the relay box by the radiator. The fuel psi regulator is on the fuel rail itself. The regulator looks like a small disk about 1.5inchs in dia. It will have a vacuum line running to it.

on OHV engine,at rear of engine block,just ahead of transaxle
on OHC on forward side above oil filter.

yes the 3.8 uses an external oil pump.

your evaprative emissions could be purging into the engine at that point too, giving too rich a mixture.

here's what you are referring to:

ISSUE: A reduced power, hesitation, stalling at low vehicle speed, idling and/or a no start condition may occur on some vehicles in hot ambient temperatures and/or high altitudes. In addition, a no start may result while the engine is still hot and the vehicle has been parked for a short period. A stall may also occur when moving the vehicle from idle. This may be caused by a lack of vapor ports in the fuel pump, resulting in a vapor lock condition or internal high wear of the fuel pump components due to tank contaminants.
ACTION: Perform normal diagnostic routines as described in the appropriate year Powertrain Control/Emissions Diagnosis Manual (PC/ED). If the condition still exists after all diagnostics are followed, replace the fuel pump with a new turbine fuel pump. Refer to the following Part Application Chart for correct part usage. Also, replace in-line fuel filter with a new filter (E7DZ-9155-A). The new turbine fuel pump will reduce the possibility of vapor lock in high ambient temperatures. Refer to the appropriate model/year Service Manual for removal and installation procedures.

Check engine light is frequently a loose fuel cap, but the other problem could be a bad fuel pump, or a clogged fuel filter. Try the fuel filter first - its the cheapest.
