Ill start by saying a couple months ago the car had the similar issue with a no start condition it just kept cranking over I did the basic air fuel spark checks. I found out the fuel pump was shot. I replaced it with a OEM Bosch fuel pump and i went ahead an changed the fuel filter too (why not).

This project then evolved into Gates timing belt kit with water pump, spark plugs, plug wires , knock sensor , cam pos sensor and crank pos sensor only because i figured i wouldn't have to do any other maintenance for awhile.

After doing all the work the car started up no issues idled fine, until i popped into Drive and there was a severe delay in the pedal finally after hammering down on the pedal fine accelerated and off i went. No CEL I drove it for a couple weeks like this mostly highway miles and it was fine if I just kept going when i stopped again i would feather the gas and off i went

Now when going to the gas station to fill up i would fill the tank up get in the car and have to feather the gas in order to get the car going while crank it over. I would have to rev the engine for a few minutes to 3 rpm in the hopes it would level out and finally did and off i went

So finally this weekend I jumped in the car and now the car is just cranking over and not starting, i triend feathering the pedal nothing this time :/

I am getting massive amounts of fuel from the main line into the filter and out( did not measure the pressure yet), the ignition coil is firing and all four plugs are wet so I am assuming the fuel injectors are working

presuming that is a OEM coil that says "subaru" on it.

how old is the battery / battery wires. (such would give hard starts and odd running / odd auto trans shifting).

what does it have for a alternator.? (factory original probably says "Mitsubishi USA" on it).

hope you put NGK plugs and wires on.

check the hose from the IACV to under the intake tubing ?

Put back old spark plugs and plug wires?

 

[Juju01]

They are not NGK wires or plugs

Looks like its not original coil pack doesnt say Subaru on it

Alternator looks newer but doesnt say mitsubishi

Battery cables look good

I dont have the old plugs and wires tossed them prematurely

The IAC tubings are fine

Ended up being the IACV i replaced it and the car is working great! Thanks for the help

maybe you can clean the old one to keep as a spare?

kinda wonder if cleaning/replacing the PCV valve would be a good idea too?

 

[Juju01]

Update: Filling the car up at the gas station still gives me a no start condition until i feather the accelerator pedal, still bizarre but now there is no hesitation or lag once it gets going

I have kept the old one just in case and I marked it with an X with the date on it just in case i forget. I will look into the PCV valve as well.

I was thinking of do a seafoam clean out as well

you might review this important thread before you get stranded:

maybe inspect the throttle cables on top of the engine.

I don't know how much seafoam will help. ...the can to use is the aerosol can,...although it might cost $13 to buy.

I would think it would do the same as dumping a whole regular $7 can onto the gas in your tank....but they way things are going you might not get through that load before you can't run anymore.

on a old ford I had IACV problems, and it the car could conk out in the road. ..very dangerous.

are you getting check engine lights.? or any other dash lights.?

 

[Juju01]

I replaced the fuel pump a few months a go with a new OEM bosch because the old fuel pump had the bad o-ring issue common with these vehicles no check engine lights and for giggles i threw the obii reader on there to see and it comes up with nothing
