Hi, I am in desperate need of advise. The other day as I was driving I noticed I was starting to lose power, I pulled into a parking lot, and killed the car. About 10 minutes later I got back in to see if it was still losing power, and after driving about a mile it completly died out. The car will crank, but will not start up. Fuel pump is good, just changed camshaft sensors, but it did not help. Im at a loss here. Any help would be greatly appreciated.

"Will turn over but will not crank" does not make any sense

Bcmill4

My bad, it cranks, but the car won't start. Sorry.

What year and how many miles on your z?

Bcmill4

It is an 03 with 130,000 miles on it.

Is your CEL on?

Bcmill4

At first, no. But when i changed out the cam sensors it came on. But i did read up on ignition coils, and it kind of fits whats going on. Thats going to be my next step.

What DTC are you getting?

[QUOTE=813_350Z;10794922]What DTC

Going to get the codes read this afternoon, and I will post them asap. Couldnt get a reader until today.

Ok, keep us updated. If it is your coil pack, I'd say you are looking at roughly 150 give or take for replacement, depending where you purchase from.

Bcmill4

Yeah, thats about the prices i am finding. I will keep updating. Thanks!

Do what you can to confirm the basics, spark and fuel and go from there. You have 6 coilpacks, it's possible that 1 or more aren't working correctly, but I'm @ 102k and have no problems with my original 06 coilpacks.

A couple other ideas to consider, the plugs are scheduled to be changed at 110k. With your symptoms I would def make sure they've been changed. While not that high mileage your cats could be partially blocked. (The symptom of power loss). Good luck.

Car won't die with just one or even two coil packs blown. Don't throw money at it until you get the codes, you probably just wasted money on the sensors, as they won't make the car die either, and both probably won't fail at the same time.

Fuel filter?

Tried reading codes, seems like the reader will not connect. All im getting is "General Error #21000".

What do you mean by losing power? Like the engine is bogging down or the volt meter is losing power? Hook up a jump box and try starting it... Even if its cranking it might be losing too much power to run the starter and the computer... If it bogged down and lost power check for clogged air filter or collapsed catalytic converters like John suggested.

Spray a little carb and throttle body cleaner into your throttle body and see if it starts...

I agree with jhc...


First thing I was ever taught.


Fuel, spark and air. If your motor isn't running. Its not getting one of those things. Your job is to find out which one and why.


If you can do that you can fix almost any car troubles.


My first things I always check, is battery, spark plugs and spark system, then fuel delivery.


If its not any of those, grab some beers, get to digging and find some codes.

As i was driving rpms just dropped and wouldnt pick up. Killed the car, it started back up, and after about 5 minutes of driving just bogged out. Ill give that a shot as soon as the weather clears up down here in la. Thank yall.
