Car Forum / Volvo Cars / October 2006Car cranks but won't start
I am not very mechanically inclined by any means. But I'm trying to figure out why my Volvo won't start right now. It's a Volvo 240D 1986. It's been very wet out lately and it stalled on me the other day. I went to start it this morning and it wouldn't budge. The engine is cranking, I can hear it, but it just doesn't start. Thinking about it being low on gas I went to the store and put in a few extra gallons plus some of the dry gas to no avail. If anyone can help me out I'd appreciate it.. Otherwise I guess I'll call a tow truck! :) > I am not very mechanically inclined by any means. But I'm trying to > figure out why my Volvo won't start right now. It's a Volvo 240D 1986.

Otherwise I guess I'll call a tow truck! :) It could be moisture condensing on electrical parts. I had a Peugot with that problem. When I was at home, I could blow warm air from a hair dryer over the distributor, and start the car. On an older car, the wiring can make it hard to start in wet weather. Dirt collected on the wires lets moisture build up. >> I am not very mechanically inclined by any means. But I'm trying to >> figure out why my Volvo won't start right now. It's a Volvo 240D 1986.

Assuming the cranking sounds normal you probably have compression so the next thing to do is check to see if you have a spark, if that is present then you have a problem with the fuel system. Report back what you find out and we'll go from there. > Well you need fuel, spark, and compression for it to run.

That's the preheat tube, I usually just yank those and toss them, if the airbox thermostat fails the hot air from that tube will kill the expensive AMM and unless you live in a cold climate the preheat tube does little. > That's the preheat tube, I usually just yank those and toss them, if the > airbox thermostat fails the hot air from that tube will kill the > expensive AMM and unless you live in a cold climate the preheat tube > does little. Oh okay thanks. Well I live in Maine and we have pretty cold winters, but if it's not a huge thing I probably won't worry about it.. >... > That's the preheat tube, I usually just yank those and toss them, if the > airbox thermostat fails the hot air from that tube will kill the > expensive AMM and unless you live in a cold climate the preheat tube > does little... ...except cause you to fail the smog test if it's cracked, torn, or missing. Looks like it was the Fuel Pump Relay.. That's what my mechanic told me. Total came to about $120 Thanks for everyone's input! :) > Looks like it was the Fuel Pump Relay..

Total came to about $120 > > Thanks for everyone's input! :) For future reference: In some model years (iirc), the hazard signal relay is the same unit as the fuel pump relay. Check your manual to confirm but might save a towing bill in the future. > > Looks like it was the Fuel Pump Relay.. That's what my mechanic told > > me.

All injected models up to '77 and LH injected models up to 1984 do use "plain normal" relays that are used elsewhere, but all the rest use specific fuel pump relays. Of course I'm not sure about non North American models, but I'd assume they're the same.  SignatureMike F. Thornhill (near Toronto), Ont.

It was specifically a fuel pump relay. >> > Looks like it was the Fuel Pump Relay.. That's what my mechanic told >> > me.

First you say you don't know of any Volvo like this. Then you say some injected ones up to '84 use relays that are also used elsewhere. Sounds like you're contradicting yourself...*g* I guess what you're saying is, later models like the OP's '86 are not like this. I'd have to agree, after chasing my fuel problem, that the ones that have the relay on the left of the doghouse in the driver foot well have specific relays. Those like my '83 that have two relays behind the panel under the glove box, use a generic relay that could also be used elsewhere. What I know is, all I could say was sonoma beach when I read that there was another relay just like my fuel pump relay under the dash that I could have switched and maybe got home on my own wheels. I'll backtrack and find where I saw this tidbit. I didn't confirm it on my '83 as it requires tunneling into the dash but if the trade off were another $160.00 towing bill, I think I'd start digging. > >> > Looks like it was the Fuel Pump Relay..

The statement was the fuel pump relay is the same as the hazard relay, which it's not. It can be the same as other relays, depending on the car, but not the hazard relay. SignatureMike F.

It's not the hazard relay, it's the central lock relay... http://www.eeuroparts.com/productdetail.aspx?code=7296 >> I am not very mechanically inclined by any means.

SignatureMike Lindsay It could be a fuel pump relay, or fuel pump. |
