Filled gas tank and was driving home stalled 3 times checked with scanner code P0607 showing ecm failure. Sent ecm to be rebuilt now car will not start. Cranks but that’s all

 

Who fixed your ECM? And are any codes stored?

 

The company is G7 in a town south of Rochester NY. They sent me a note that the problem might not be ecm. I filled my gas tank and car stalled out 3 times coming home. Hooked up Innova 3120 and the code was P0607 indicating ecm. I am wondering if it’s fuel pump or ? Replaced plugs and coils prior to this. I don’t want to go to the dealer again. Thanks

 

When googled (is that a word?) I find a G7 company that does "fix" automotive stuff. If you think it's an ECM problem and want someone that has the most experience - you could try xemodex.com.

Or that generic code may not tell you much - https://forums.swedespeed.com/showth...426-Code-P0607

But - I'm sure it's possible - however in 19 years of fixing 1999+ canbus Volvos, I never had to replace a bad Engine control unit.

 

This is crazy. Had a 89 240 wagon and same thing full tank and wouldn’t start the next day. Also a dodge pickup same thing that needed fuel pump. I know I probably won’t be able to figure this out alone and appreciate the help. These cars are so engineered it makes it tougher. What do you suggest?

 

A reasonable diagnostic process - I always used VIDA that would give concrete suggestions, and live data could be monitored. For a 2002 a fuel pressure gauge would be helpful also, fuel pressure is not in VIDA for that year - The canbus cars can be very hard even for a professional to diagnose properly - the first time.

"Hooked up Innova 3120" - the $150 one? Vida is free, you just need your own win 7pro cpu and a ~$80 dice unit. Or a guy sells Vida on a bootable USB stick for $100 (plus a Dice unit)

 

Bought Innova OBDI/2 with attachments for a94 pickup years ago. Yes I have seen the one you mentioned sounds like the answer. Thanks

 

my problem is related to this thread, but, i am not answering the initial problem, drove a couple of miles to grocery store, came out 5 mins later, car cranked, almost caught, than failed to start, tried again, crank, no start. *#Y%. well, tried cranking enough times to run the battery down. later in day, picked-up battery, charged for 4 hrs, put back in, fired right up. i've already read through enough 'reasons' the car wouldn't start, but, did not believe that was my problem. could removing the battery for a few hours and installing back in, fully charged, cleared any conditions that may have prevented the car from starting ? thanks
