My 1991 Volvo 740 will start sometimes and then at times it wont. I have replaced the in tank pump. Fuel is getting to the rail still no start.


You really need to get a code, if possible. If not, you can try to check if your getting spark. It could be the spark plugs/coils, wires, distributor, cap, or rotor. You might not be getting enough spark all the time. Best bet, if your check engine light is on, take it to Autozone and get a code. They do it for free. They can tell you what you need hopefully. If you need anything, feel free to contact me. I am here to help.

Adaptive idle control - 1991 volvo 740 -B230 engine


I suggest you check your fuel pressure and your Mass Air Flow Sensor (MAF). The fuel pumps and the MAF often fail causing these symptoms, but there may be other issues too. I suggest you take it to a qualified mechanic to avoid replacing unnecessary parts, since there are several possible problems.

On the 92, the belt closest to the engine goes around the power steering pump, water pump, and crankshaft pulley.

The second belt goes around the alternator and the crankshaft pulley.

The third belt goes around the a/c and crankshaft pulley.
