Question about 1986 Ford Bronco

1988 Ford Ranger 2.9 V-6

My old truck won't start . It's has 40 lbs of pressure at fuel rail and 36 psi when it does start . I can get it to run for about 30 seconds until it shuts off . I've already replaced both ignition switches along with the MAP sensor . It is a very basic fuel injection system but I can't figure it out . Any ideas would be great help .

Check injector pulse width first, might have a defective injector.
could also be the EEC-IV, this is the computer that controls the delivery side of the fuel system.

but first like slappy said try the relay just because of simplicity and access.

I have a 1988 ford ranger 2.3l 2wd. How many lbs pressure on radiator cap should i have?


1988 ford ranger -years 1983-2011 ( sub catagory not stated so custom was selected )---12-16 psi
research shows that most fords run a cap operating at 16 psi with a minimum of 14 psi to a max of 18psi
go google and type in radiator pressure for ford ranger 1988 model and there are pages and catalogues for caps relating to ford
There is a slightly higher cap requirement for a diesel engine
go to your local radiator shop and they will have the correct cap for your radiator --prices $10.00 -$20.00 us depending on manufacturer

Some models have a fuel pressure service port on the injection fuel rail. Test pressure running should be around 36 psi shut engine off if drops to zero then pressure regulator is leaking into the return line.

Starts then dies & won't restart


check fuel pressure, should be 40 psi.
try 2 things

spray starting fluid in air intake to see if it will stay running. It's fue then.

Try turning key to on nd wait 5 seconds for system to build pressure and pump to shut off. Turn key off, wait for relay clcik noise or 10 seconds. then turn key to ON again and wait 5 seconds to build pressure again. Then start engine. If it starts better, you have a bad check valve in the fuel pump or a bad pressure regulator on the fuel rail (unlikely).

What is the ideal operating fuel pressure for an 89 Corvette w/ LT-1 TPI


The 5.0L injector is sized to deliver approximately 4.05 milligrams of fuel with a 2.5 millisecond pulse or 18.13 lbs per hr at approximately 36 PSI. The 5.7L injector is sized to deliver approximately 4.83 milligrams of fuel with a 2.5 millisecond pulse or 23.92 lbs per hr at approximately 43.5 PSI. This information is typical for all manufacturers and flow rates will vary slightly even between identicle injectors.
Good luck and hope this helps.

1988 ranger will shutdown after 30 to 40 minutes of driving and wont start for about 30 minutes


It sounds like your ignition module is failing after reaching a temperature threshold, this occurs when the component's sealed silicone housing dries out and tends to ground out or leak voltage. The component is located on the back side of the distributor housing if memory serves me on the V-6 engines they are a pain in the neck to reach and I am pretty sure the bolts that hold the ignition module to the side of the distributor are torx head machine bolts. If this doesn't fix the problem check the fuel pressure at the fuel rail it should read 30 - 40 psi or pressure if not replace the fuel pump.

1988 mustang 5.0 efi flooding engine will not start fuel pump constantly running, fuel reg. replaced will actually fill and with fuel and only fire if pedal is to the floor?


Step one
Click the key forward BUT don't start the car listen for fuel pump to pressurize and shut off. But if the pump keeps running change the fuel pump relay switch under drivers seat. If its pressurizing and shuts off then its not your fuel pump. Fuel pressure at rail when idling is 30 psi.
Let me know what happens cause I know alot about Stangs had 2 5.0

Fuel Problem


fuel pressure regulator? This diverts excess pressure from the rail back to the tank. When they wear out they usually stay stuck open thus diverting all pressure back to the tank. Pressure tests do not reveal this as pressure is checked before the rail not in it. I do believe you have a bad fuel regulator. They are 75US ouch.
