Re: 1988 Volvo 740 cold condition, started short, cannot...
Check the fuel pump fuse and fuel pump relay first, before replacing the fuel pump. The fuses and relays are behind the the ash tray, The fuses are labelled. The relay is on the left side of the relay rack, closest to the big round bulb out sensor.
But before that, how about pouring some gas line anti-freeze or fuel injector cleaner into the tank?

Hello. i have owned many 740's, 240's, 122's, and 850's. I have done my fair share of transmission swaps. The transmission tag is located right above the trans-oil pan and directly below the od seloind on the drivers-side. if your volvo 740 is a non-turbo, the transmission is AW-70L, if it is a turbo-model then it is AW-71L. Good luck :)
One way that always works is to disconnect the battery for at least ten minutes. If the cause of the check engine light turning on in the first place is not fixed, then the light will come on again pretty quickly after starting the car. To reset your service light here are the steps.
1. Get in your car and shut the door. 2. Put your key in the ignition 3. Turn your ignition key to position 1 4. Push in your Odometer reset button and hold it in while holding it move the ignition key to position 2 while holding down the odometer reset button. 5. After couple of seconds of holding the button down and the key in position 2 your service light will start to blink once that happens let go of the reset button and start the car.
try pushing the 4 wires on the radio supression relay into the connector, then try starting it... does it start, run, then die? those connectors ****, i've had the same prob. have you let it huff on some ether? (starting fluid) does it come to life? that would confirm weather or not it its fuel related. my 740 i was loosing voltage to my injectors 10 volts and under, causeing them to inttermittantly not fire, caused by a bad connection at that supression relay.
