Default 2004 STI no crank no start every now and then. Please help :(

TLDR: purchased car and it needed some work. It has a freshly (2k miles ago) built motor/transmission refreshed(? //fixed)/fuel rails,pump,injectors/replaced the starter/battery. I turn the key and I hear the starter click but no start. I made a clutch jumper wire, so I donít need to depress the clutch to start the car(I thought the clutch wasnít grounding out )




Also I get a misfire in cylinder 3 almost every time I get gas(91 @ chevron/shell/76 only. per shop who built my car request) not sure if this is related at all.

Iím at a loss on what to do now. I plan on calling the shop tomorrow but also want the internets thoughts on this as well.

You replaced the starter with a new one? OEM or something aftermarket?

A click from the starter itself (not a relay or something inside interior) could mean a solenoid/plunger contact issues. It may unstick after a few key turns or if you can get someone to tap it with a hammer + extension to dislodge while you have the key turned to START.

Make sure the connections are good and tight on the positive terminal and spade (no corrosion) and ground bolt eyelet (top bolt) on starter unit, same with the battery terminals and ground.

If you still have the old one, swap it at worst case.

I replaced it with a duralast remanufactured starter. I donít have the old one, I sent it in for the code charge.
I have replaced the spade connector on the starter Solenoid and the ground and power cable looked good but Iíll check it again this weekend.

Remanufactured starters / alternators / etc. are not very good and don't last very long. Typically these are rebuilt cheaply. Bad rebuilds are a constant issue.

Now, could be something else but very well could be the starter. That's why I purchased a Denso when I replaced my OEM starter.

As for the Cyl #3 misfire, could be a lot of things but I'd start with checking the plug, igniter and igniter connector. Something could be bad or loose.

You can swap the plug w/another cylinder and see if the issue stays with Cyl #3 or moves to the swapped Cyl. If that happens, it is a bad plug.

If it doesn't move, then swap the igniter. If it moves, bad igniter.

It's a slow process but in the end can save you a lot of headache & cash from buying replacements you don't actually ned.

I've had the generic autoparts starters/alternators go bad immediately before, especially most recently. I don't know if they are just putting in bad parts when they rebuild them or something.

This starter has less than 200 miles on it, do they go bad that quickly? Is there a way I can test this starter before I buy another?

You can test by taking it out of the car and supplying power directly via battery, with something like jumper cables (it'll be sparky). Negative to the casing/flange of starter body, positive to the terminal. Additional positive (or try to contact both to the positive clamp) to the spade and you should see it starter pop the gear forward and spin. If it doesn't do it, then your starter is no bueno.

Also, some auto parts places or shops can test it for you if you're uncomfortable with the procedure.

They can be dead out of the box or after a few miles. I replaced an alternator 3x times in less than a month from NAPA before I gave up and bought an OEM.

I used to not have an issue with them, but within the last 2 years, store-brand reman units have been problematic. Starting/charging units to need to be reliable or it'll leave you hanging.

Your Duralast should have a warranty, you can also just keep swapping starters until you get a good one if you want.

Iíd start with the following:

With a Volt meter - Check battery power, disconnected, then when cranking and when sitting while connected.
Check connection to the starter, when idle and when cranking

Have you tried a bump start? This to me sounds like an electrical gremlin of maybe a ground strap or low voltage that isnít super consistent.

I will try this as well this weekend.
And usually the bump start method is the only way I know how to fix it at this point, itís annoying especially if Iím alone.

Iím finding out this car has multiple gremlins living in it. Do you know the locations of all the main grounds on Subarus?
