2.9 L starting trouble 1986 ranger

[Colepitts]

I sprayed gas down the intake it will hit

 

[Colepitts]

Then the injectors arent getting the signal to fire

Where would the control for this be? / plug or wires

 

[Colepitts]

OK, I found the plug plugged it in. It ran for probably about 30 seconds and then cut back off. It will hit if I give it a little bit of throttle but we’re not run now.

So itll run on throttle but wont idle?

 

[Colepitts]

It’ll do both if you give it starter fluid but not either with out it

Ok so its a fuel issue.

Check your pressure at the rail...if that checks out the ECM isnt grounding the injectors to fire them

 

[Colepitts]

I have good pressure at the rail. Now it is the trouble shoot for grounding

 

[Colepitts]

How and were are the grounds for the injection / ecm

Pressure is 39 psi

Pressure is 39 psi

Then its the wiring between the injectors and ecm or the ecm
