You may want to check the noise suppression relay under the bonnet. A black relay with 4 wires either in front of the coolant tank or by driver side strut.

The fuel pump only runs for exactly 1 second when the key is turned to the run position, then the computer shuts it off unless the engine is being cranked over with the starter or it is running of course. If you wish to prime the system repeatedly turn the key to run and then off again until engine starts while holding the accelerator pedal to the floor to help purge air from the injectors.

My volvo 740 non turbo car has resently failed to start i need some ideas on what to do, When i try to start the car it will crank but will not turn over and start, this is my first car so i have no idea...


the engine is either not getting fuel, or is not getting spark. with the ignition key in the "run" position, listen under the rear of the car (near the fuel tank) for the sound of the fuel pump. or, after cranking on the starter for a while, remove a spark plug and smell it. smells like gas? if so, the problem lies in the electrical area. if not, fuel is not getting to the engine.

Engine swap, car will not start


It sounds like you don't have the correct flex plate and it is throwing the timing off not letting it fire at the correct time.
