I think we have narrowed it down to the fuel module. I am going to try to get a used part first and/or a new part and install it myself. Failing that I have CAA TOWING COVERAGE to help my friend out.
Thank you for the cautionary advice.The Northerner
I exercised every connection under the hood except the ECM. I exercised the fuel pump driver module connection. I erased the codes and the mazda started. I let it warm up and took it for ride up and down some steep hills for about mile and the fault returned. I scanned for codes and OBD showed just the fuel pump driver error offline or disabled.This suggests to me that an internal contact swells once heated with use and then shorts out. Does this sound plausible?
thanks
The NorthernerMr. no_common_sense this response seems like uncommonly good sense to me. I have had success with simply exercising partially corroded electrical connections. I will do that this afternoon and post the results.
I will ask you also is it safe for the lady to drive the car to the mechanic or must it be towed in?
thanks for this.
The northenrerNo I do not have an automotive multimeter or the knowledge to use one without frying sensitive components. Your thoughts agree with the post below so I will take a look at that module.We needed a basic understanding of what is going on so the unscrupulous tech can’t rip my friend off.
In your opinion can the car be safely driven 1.5 miles to a garage or should it be towed?
thanksThe nurse who owns this vehicle purchased it at 8 years of age with about 194,861 klms on the odometer. If 20,000 to 24,000 kilometers per year is average it was driven at a rate of 24,358 kilometers per year for the first 8 years of it’s service life. That is high for just around town driving so it must have been out on the highways a lot. For the past 3 years it has averaged just 10.000 Klms. per year. That is indicative of casual use just around town.
This SUV has 224,861 kilometers.
I should have asked is it safe to drive it to a mechanic 1.5 miles away on city streets? 30 miles an hour max. Or does it have to be towed in?
I am asking on behalf of a nurse who works with mentally challenged adults.
Thanks
The Northerner.Well it could be only part of the problem. It won’t start at even ten bellow C degrees unless the block heater is plugged in to heat the oil.That’s not really very cold! A healthy ignition system will start a 2.4 Lt. at as low as 30 degrees C below zero. This is an 11 year old ignition system and we’ve had three hard winters with temps down to 45 degrees below zero. That’s got to be hard on all electronics. I think I have a weak spark at two or more of the plugs, so since they are new I’m going to start at the coils and check back to the igniter. What do you think? does this sound like a reasonable approach?
Success! Just 5 attempts at ether spray and cranking and the dry gas was up to the combustion chamber. I though it would take a lot longer than that! It snowed all day yesterday and all night giving us about ten inches of nice cold dry powder snow. I think you can guess where I’m going now. Yup out to play in the snow with the 04 CR-V!
