85 740 GLE Non-turbo stalls when put in gear or push on accelerator
Volvo 85 740 GLE Non-turbo starts fine, but stalls when put in gear or push down on accelerator. Fuel pumps, filter, pressure regulator are all new AND test okay. Throttle switch is rigged correctly, but do not know if is okay. Please advise.

Had same problrm with 88 240. Turned out I have bad wiring to main fuel pump. It's a simple check. Crank the engine then turn off before it stalls. Put on some goggles, put out your cigarette, and carefully crack loose the gas line fitting at the fuel rail (17mm & 14mm wrenches). Gas shouls come flying out under high pressure. It seems the tank pump provides enough pressure to idle the engine. If the gas is not flying out like mad check to make sure you have voltage to and through the main fuel pump.

This is a common problem of Volvo S40. You can try this trick to turn off the flashing arrow light.
1) Turn off Engine
2) Turn key to "On" position (Not start the engine), you will see the panel light will on
3) Step on the break paddle
4) Shift the gear from "P" to "L" 10 times
5) Turn key to " Off" position
6) Now you can start the engine.
7) If doesn't work, you can repeat the procedure.
Have you tried replacing the fuel filter? It is located under the cars center on the left side ..
You will find it alongside the main high pressure fuel pump on a metal
support plate held up with 3 bolts. Remove the 3 bolts with a 10mm
socket wrench to lower the plate. Place a catch pan below the filter to
catch any leaking fuel. Be careful not to get fuel in you eyes or
running down your arms. Remove the 2 bolts holding the banjo fuel pipe
connections to the filter. Note the direction of the filter. Loosen the
clamp holding the filter to the support plate and slide out the old
filter. Install the new filter in the same direction as the old one and
use new copper sealing washers on the banjo connections.
