Vacuum leak, oxygen sensor or possible bad air mass sensor. Disconnect the mass air flow sensor and it will go to a default but stay running. If not try disconnecting the oxygen sensor and see if it stays running.

Can I change the fuel pump and relay on my 1988 Volvo wagon 740 myself or do I have to have a mechanic do it?


dropping fuel tank is not that hard, drive up on ramps for clearance and unbolt straps, be careful not to break fuel line when lowering tank, good luck

1989 volvo 740 gl. Put new starter in, now it


i cannot remember but i think there is a starter relay, its located in the engine bay the wire color is the same as its is on the starter motor, and feeds back to the relay, in the relay box in engine bay if this model dont have the relay as some models did not have it fitted and it was a straight from the ignition it can cross over on the ignition switch, and that would need to be replaced, or changed to button press, were by cutting the wire on the starter wire on the ignition and feeding it to a switch button.

Not starting after replacing fuel filter and tune-up


I had the same problem with a 1989 Volvo 740 GLE station wagon. I did the same thing you did. But this time I talked to the local Independent Volvo service shop, not the dealer. The problem turn out to a bad fuel pump in the gas tank. You can replace it from inside the back of the station wagon. Just remove the floor panel to access the top of the fuel tank. But before you do; note that there are two fuel pumps, one inline underneath the car on the drivers side, and the one inside the gas tank. Before, you replace any of the fuel pumps check the fuel pump relay behind the astray on the left side. It could also be a bad relay.

1988 Volvo 740 cold condition, started short, cannot start again


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?
