    Eric,

    I guess your check engine light comes on then goes out.Did you know that the check engine light comes on when it is time for an oil change? After an oil change, press the resset button on the dash and it shouldn't come back on until it is time for another oil change. BEFORE you resset it, pull the rubber thingy over the button off and if the check light doesn't come on after you start the car, then that's all it was. I hope.

    Let me know.

    Cheers,

    Ken

I'm having trouble locating the starter on my 1990 volvo 740 gl. where is it located and how do i replace it?


As you are facing the car, it is on your right hand side - low on the engine - toward the rear of the car. To remove, 1) remove the positive battery cable 2) jack the drivers side front of the car up 3) from above or below, remove all electrical connectors

1990 volvo 740 wagon shuts off while driving


sounds like you have a computer glitch. i would take it to any auto shop and pay 50 bucks so they can take a look at your e.c.u. (engine control unit) we had a similar problem a few years ago with our 1990 volvo 740 gle 2.3l station wagon. it was a glitch with the computer. got a mixed signal with the mass air flow sensor.

Volvo 740(1990) i replaced my coil and change the battery, it started, then went 50 yards the it died and now it just turns over, but won`t start, is there anything else it could be? thanks


Many things can cause this on your 740. Fuel pump, fuel pump relay, rpm sensor, MAF sensor, radio suppression relay. I've never seen the coil fail on these era Volvo's, ever. And I've diagnosed at least 50 of these with stalling problems. Check the codes, and when it wont start, check for spark and fuel pressure, you're likely missing one of them.

Fault test shows no knock enrichment signal from ignition system


Is that the only code? Make sure you check terminal #2 and #6 when checking codes. I don't think the code for knock enrichment should cause the light to come on.
