SOURCE: 1985 Volvo 240 no fuel no spark

well first the fuel pump relay is bad, that is easily replaced. next you have no spark. the first thing you do is take the cap off the distributerand crank the engine. if it spins that tell syou thyat at least the tang or gear on the shaft of the distributor is ok and not broken. next thing is remove the #1 plug and use a 1/4 drive extension 6" long and turn the crank by hand until the #1 cylinder is top dead center(put the extension in the hole of head where the plug was and you should feel the top of the piston also make sure you can feel the top of the piston with half the extension this way you don't drop it in the cylinder with the piston at TDC(top dead center) the rotor of the distributor should be pointed at the #1 firing position. IF it does not that means your timing is off and you need to retime it by taking off timing cover and either replacing the belt/chain or gears. now if you do not have a distributor and you have a coil pack there could be only 2 things that won't give spark. either a bad coil or your altenater is bad(the battery is responsible for starting not running the vehicle like alot of people assume. the altenator energizes the coil which inturngives spark. hope this helps you please rate this thanks

Check under the hood for a box containing your fusible links (they look like large blade fuses in most modern vehicles). The fuel pump relay only operates the fuel pump. It doesn't provide power to the rest of the fuel system. Odds are the fuse for the injection system is blown. The inside of the cover of most fusible link cases usually has a diagram which tells what each fuse is. The easiest thing to do is locate that fuse and remove it (with the vehicle off of course) and visually inspect to see if it's blown. If it is, simply replace it and see if that corrects your problem. While you're under the hood you might want to trace the wires back to their origin and check to be sure the harness is not rubbing or chafing against anything that might have caused wires to break and short. It's rare for those fusible links to blow without a reason.

If your air mass meter tests good, the I would tell you to check the HIGH PRESSURE PUMP underneath the Driver's side chassis pump holder-next to the fuel filter.

There are 2 pumps on your Volvo---the in-tank low pressure, and the chassis mounted high pressure. The car will run with the in-tank failed and the high pressure good. It will not run with the high pressure failed. Test the pump by applying voltage to the two terminals.

Another common failure, should the high pressure pump be good, is the HALL EFFECT SENSOR located in the distributor on the back of the engine. Once this sensor goes, it's no start. A rebuilt or used distributor may be the answer to your problem.

If you have 25 miles to drive with that serious missfiring going on, I would first try to find a repair shop closer to you. It need not be a Volvo shop. Failing that, I would have it towed. Since the towing distance may be greater than 5 miles, investigate joining a road hazard protection program first (like AAA or others). Once signed up, then have it towed under the new protection. I think you will find it cost effective to do that rather than just calling a tow truck.

How do i replace the turbo in my 1991 740 volvo?


You bring it to me along with the new turbo. OR you take it to another mechanic. It will require a full set of mechanics tools and careful attention to detail.

1991 volvo turbo idles and runs ok exhaust manifold gets glowing hot after highway speeds checked and repaired all vacuum leaks had replaced air mass unit before this happened. timing by the book 12...


The Garrett turbo-charger is notorious for leaking oil into the intercooler, and, into the emissions system. This happens because the bearing wears in the turbine assembly, and dumps lubricating/cooling oil into the combustion and intercooler system. It also ruins all of the rubber hoses that come in contact with the oil.

A result of this, after thousands of miles of driving: Your catalytic converter is clogged. The backpressure from the clogged exhaust increases the manifold temperature to cherry hot!

When I had my Volvo service and sales business, I lost money on only one Volvo; a turbo-charged 1988 wagon! A friend of mine who made his living salvaging Volvos had similar experiences with turbo-charged 240's and 740's. I hate to break the news to you my friend, but you will need to spend lots of money on that vehicle.

Trust me, do not try to fix it as it's a black hole---$700-900 for the rebuilt turbo ($250 for the rebuild kit), $200-300 for the catalytic converter and on and on! When I bought that vehicle from the original owner, It had a stack of repair receipts an inch thick!

The only recommendation, if you must keep and drive the car: remove the turbo-charger, intercooler, and all attendant hoses. Replace the air assembly with one from a normally aspirated B230F, and keep the airmass you just installed. Replace the catalytic converter with a good used one if you can find it.

1991 740 Wagon electrical problems


Was the car primarily in a Southern state--no winters? If yes, it could be the wiring harness that leads to the rear wiper/stop light inside the rear tail gate. They usually break at the flex point, and short to the frame.

I had a 87 740 turbo wagon, It ran a 10.9 1/4 mile man was it fun. I hate to say that your turbo is nearing the end of its life. The only thing you can do is replace it. there are speciality shops that specilize in turbos. if you can't find one close check out a Diesel truck shop, they deal in turbos too. maybe you can have it rebuilt a little cheaper, or I can tell you how make it pass a Corvette. Good luck.
