I just bought 94 ranger 4.0 ..guy said he drove it turned it off got out out got back in wouldn't crank..Sat for year.. I put fuel pump,filter...it will crank as long as I spray it with gas..what can I check

 

[rusty ol ranger]

Its starting if you spray gas in intake?

Probably the relay or inertia switch

Can you hear the fuel pump run when you turn the key on?

 

[Hammyclause69]

Not inertia switchh...or relay....fuel pump is running

Is fuel getting to the fuel rails?

 

[Uncle Gump]

Check your fuel pressure...

 

[Hammyclause69]

Fuel to the rails

 

[Hammyclause69]

Not sure about fuel pressure

 

[sheep herder]

Fuel to the rails

Could be: injectors not firing or injectors plugged.
Pull a spark plug and see if it's wet after cranking. I'm betting no on that one.

 

[Hammyclause69]

I've pulsed injectors a few times with jumper wires

 

[Dirtman]

Have you tried yelling at it?

 

[Hammyclause69]

Yes I have

 

[JMF661]

Bad spark box?

 

[rusty ol ranger]

If the fuel pump is running, and it will fire with fuel dumped in the intake, then you have an injector issues/ecm issues.

Seeing as how its all 6 at once id lean toward ECM, but check the grounds on the injectors, not sure where they are on a 4.0

I would check for injector pulse with a noid light. These injectors are supplied constant power and ground side switched.

Also before you do much of anything else... you NEED to check fuel pressure. Just because the pump is new and runs... doesn't mean you're getting the correct pressure.

Pulled injectors cleaned them,took probe wires and pulsed them they are not clogged....on way now to get something to check fuel pressure.....
