So my car died unexpectedly yesterday. While leaving my parents house and pulling onto the road, my car just died. Was going maybe 5-10mph and accelerating and the car just dies. Go to restart and the car cranks but will not start.

Push the car off the road and do a quick check. Timing belt was fine (only 6 months old). Car has 64k on the clock. Battery was a little low and eventually wouldn't crank. I figured I had a bad battery so picked up a spare battery from my parents house since we were visiting them. Car cranked better now but still wouldn't fire.

I have a scangauge II attached in the car and when I went to check for codes, the think wouldn't link up to the ECU.

I got the car towed to my mechanic. He called this morning and said after checking fuses, relays, they can't find the problem. He said the ECU has power, but that the line to the Fuel pump is dead. The fuel pump isn't getting any signal from the ECU. They also couldn't get any scanner to connect to the ECU to check for codes.

So now my car is off to the dealership to get checked out. Fuh!!!!

Anyone have any ideas or had something similar happen? My car is pristine. I am up to date on all maintenance. It seems like a fluke problem?

 

Check ur fuse box for any blown fuses. Theres one under the hood near the ecu and theres one under the driver side panel (below steering wheel if that makes sense)

 

Have your mechanic check if the fuel pump relay is clicking/getting power before you spend any real money at the dealer.. Spark and fuel are two reasons why a engine won't fire if you have spark than there must not be fuel if you have fuel than you must not have spark if you have both than timing but that's not the case here since the comp adjust timing and the belt is fine. Check wires/connector at the maf.. How did he check to see if the pump was getting power? if you know...

 

ECU is getting power but the fuel pump is not getting any power.

 

I'm pretty sure te ecu doesn't send power to the pump directly but to the relay to close it

 

my guess is your fuel pump just took a dive?

 

The problem is the ecu will not connect up with any scanning devices from the port underneath the steering wheel. It is like the ecu is down and non responsive. I don't think the fuel pump could cause that.

 

when you turn the key, do all the indicator lights come on?

 

I dontthink your ecu would just die all of a sudden.. You sure he plugged it in the right port

 

there's only one spot it will go

 

All dash lights come on as normal. All signals, lights, radio, door locks work. Unfortunately it is at the dealership now to see if they can locate the problem. I will likely have the dealer diagnose the problem and then have AAA tow it back to my mechanic for the actual work.

 

Theres the other connector next to the obd2 link.. The first time I hooked up a scanner I put it on and was like wtf not reading looked and seen it wasn't the obd2 link

 

lol, fail

 

sure the battery terminals arent just corroded? might be ok for ACC, but for everything else.....

 

Battery terminals are fine and have zero corrosion.
