We are driving home to Idaho from Texas in our 1986 ford ranger v6. It started acting like it was vapor locked, we fueled and added fuel injector cleaner, it ran fine for the next 300 miles then started it again. We pulled in and have changed the fuel filter and fuel pump also a vaccum line. We primed it with starter fluid and it started ran for a minute, sputtered and died. It won't stay running, like it is not getting fuel. 'what now? would really like to be able to make it home for easter. am currently stuck in new mexico.

It could be a vapor lock but not likely. Since the introduction of fuel injection vapor lock has been eliminated. You need to figure out if you are loosing fuel pressure or spark when it will not start back up. Could be a fuel pump relay or ignition module among other things. Even a problem with the vent for the gas tank.
Fuel caps have breather holes in them - once clogged the fuel tank is sucked vacuum and the engine stalls. Check the fuel tank cap for clogged breather holes.
Yes there are two (2) fuel pumps on these pickups, one low pressure one in the tank that gets the fuel to the high pressure pump which is in the inside of the drivers frame rail beneath the cab towards the front of the cab.
U need to verify the fuel pressure during this time that is acts up.if the fuel pressure drops below 30 psi then u may have a faulty fuel pump.you can get a fuel pressure tester from advance auto,Install the tester on the test valve on the fuel rail.Your truck has two fuel pumps but the main supply pump is mounted on the frame rail underneath the drivers side floor pan.
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.

your having a weak spark issue you will need to remove your distributor to replace the pickup or the coil is breaking down sometimes this can be the egr but be careful removing this as not to break the intake hope this helps
p.s i had one with 2.9 and cured this problem on mine pick up in dist was weak but this could be emission also have any codes? good luck
if your obd2 scanner fits the connection you have obd2, obd1 connector is way differnt.
your code p1443 Control System Canister Purge Valve (Mechanical) Malfunction Monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM. l Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister) l Damaged EVAP canister l Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister) l Damaged EVAP canister purge valve Check for audible vacuum noise in the engine compartment or significant fuel odor in the engine compartment or near the EVAP canister.
This link has all the codes you need. http://rockledge.home.comcast.net/~rockledge/RangerPictureGallery/DTCs.pdf
yes it is fuel injected.
I changed the fuel pump and the filter.
