Help! Car won't start after Coilpack/spark plug change

you can only do so much on pump gas and with that being of questionable quality why push it?

 

True.

 

heart dropped when I read this.

Let me know if you need anything besides truck/trailer.

 

it should. Last time we compression tested Dana cars my compression tool broke off in the plug hole, King had to get it out. However, King couldn't get it out till the next day, so Dana drove the car home w/ zero compression in one cylinder.

It should still start. The fact that there's compression means there will be something in the power stroke, enough to hold over the inertia till a stronger cylinder fires.

 

That was only one cylinder, the theory is if 2 are low.

Edit: still have you compression tester lol

 

big diff in just one low and two being low. Just like you can run car off 3 coils but 2 it'll struggle if run at all.

---Sparta beat me to it

 

It should still start. I had the coil pack connectors backwards on two cylinders and my car still started.

 

low compression is still compression.

I'm not saying it'll run like a champ, but it should still fire up. I've seen single cylinder 4-strokes run before - that's one power to compensate for four total strokes.

 

This Sam's car?

 

Yes

 

Man that sucks. That girl has had nothing but bad luck on her cars lately.

 

Yea she's devastated. Looking to drop in her spare longblock and sell the car.

What's sad is she doesn't abuse them, she drives like a granny

 

Why not return car to stock and reliable? It's sad as you see this happen more often than not

 

Need an intervention for the next car then. I can't imagine the feeling after all the problems and then returning it to stock, I don't know if that's realistic to expect anyone to do that. You can put a front mount on with the stock turbo, and fancy blow off valve, and suspension without changing turbo/injectors/fuel pump/high hp tune. She needs to keep it simple for the next car.

I put 50k miles on my car already, very light tune and you know how I drive on the weekends. It has yet to even wince once.

 

In your case the FMIC is a waste until get get bigger than a 20g. Shoot Doug ran a GT35R on the 08+ TMIC....it's a great IC stock for the 08+ years.

 

I know, hell my favorite thing to tell people when I was into DSM's, was Buschur Racing running 10's in the 1/4 with the stock side mount IC. However, if you want a front mount for the sake of having a front mount, it is your money. You won't see me with one trust me I like efficient mods, least modifying to get me where I want to be.

 

I will have a front mount heat exchanger

 

There is 100% no way that low compression on two cylinders is keeping that car from starting.

 

That's what I figured which is why AllPro's gonna drop in her longblock. I'd hate to do it at the house and run into the same problems.

 

I would have them check that ecu first, you are doing a compression test on a cold engine that hasn't been run in a while. A compression test on a hot engine can yield vastly different results.

 

something is up with the battery and terminal change, have you checked the fuses and relays?

 

Yep pulled every single fuse and inspected each one.

 

It wasn't starting before messing with the terminal which is why I changed it to rule out the diagnoses of it being a bad connection.

 

yeah, i think the consensus is an ECU. borrow a known good one from someone to test before doing an engine swap

 

^ this, if battery had power while changing coils. it's a long shot but if something finds a ground and fries a circuit, that's it.
