My 94 850 turbo wagon has been just up and dying while driving on city streets. Not good while I was teaching my daughter how to dirve!! Oh well she got a quick lesson on what to do when you loose power.... I replaced the fuel pump and filter and it was fine for a few days but now it's back to it's tricks.... I'm going to replace the relay and see if it fixes it... It usually starts right back up though once I did have to tap by the relay box...I'll report back after I do the relay but any other ideas??

Relay should fix it. [&:]

 

Hi Tim,

Check the codes at ECU. You can manually access the ECU on '94 models. MAF sensor has been giving people engine dying problem lately. Check this out too:

Let us know if you find any code so we can narrow down the problem.

I checked and there were no codes. Looking at the history of this car it has had the MAF changed out in 2004 and 2006.. How do you test that part??? Thanks for all the advice.
BTW,, I fixed my seat back cable with the methods found on this forum. THANKS!!!
Tim

 

Hmmm.... two MAF changes so close together is kind of odd. Might start looking there as JPN suggested.

Just remember. when you lose power, you either lost fuel, spark, or air intake as they are what is needed to support combustion. Check for each one individually and you should find the cause of your problem

Good luck,

Glenn

 

You need to figure out what you loose when it dies.
Spark
fuel
injection pulse

 

I replaced the MAF and the relay. All seems well in fact it runs better than ever...Thanks, Tim
