Engine turns over fine, but won't start at all. Had this problem yesterday it seems as if the engine isn't getting any fuel. My gas gauge said there was a quarter of a tank left. But adding fuel solved the problem. Today I went to start the car and it's having a similar problem but theres half a tank of gas. It reached below freezing temps last night if that helps any. I used a match to check if there was gas in the gas tank and there def. was. Many thanks in advance!

I don't hear the fuel pump, bad pump? | | | 04-08-2009, 07:37 PM | #5 | Junior Member Join Date: Mar 2005 Location: North Carolina Posts: 15 | So it's def. the fuel pump. I'll have to order a new one, I didn't see a write up already posted on how to do it? Should I write one as a go? It seems pretty straight forward tho. | | | 04-08-2009, 08:37 PM | #6 | Member Join Date: Apr 2008 Location: Pittsburgh, PA Posts: 90 | | | | 04-08-2009, 08:40 PM | #7 | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 | Quick test to see if you're getting fuel is to pull a sparkplug and sniff. To check fuel pressure, disconnect the fuel filter (it WILL spray everywhere; wear eye protection and have a place for it to go). Or just have someone start the car while you sit in the back, ear to the seat. You can normally hear it start humming. __________________ I scream, you scream, we all scream for ZOMBIES. | | | 04-08-2009, 09:19 PM | #8 | Senior Member Join Date: Apr 2006 Location: Oxford, Ohio Posts: 868 | Check out my post (#8) in this thread: http://www.318ti.org/forum/showthread.php?t=22695 This way you can check the wiring and operation of the fuel pump before buying a new one. | | | 04-09-2009, 02:23 AM | #9 | Junior Member Join Date: Mar 2005 Location: North Carolina Posts: 15 | Thanks everyone for the help. We've been working on it all day. We checked all the electrical at the front end it was good. The pump wasn't working at all we worked from the fuel filter and started to disconnect hoses working our way to the rear to see if there was a hose that was bad once we got all the way to the fuel pump and still no fuel was coming out. so we pulled the pump and tried it then. of course fuel sprayed all over the place! go figure. so we reinstalled everything. it appears to be running fine now? i'm not sure if the problem is intermittent or what? we have a new pump on the way but i'm not sure if we need it now? i was thinking of replacing it because this is the second time we've had this problem. opinions? Thanks the help! Justin | | | 09-15-2009, 10:40 PM | #10 | Senior Member Join Date: May 2006 Location: Memphis, Tn Posts: 1,299 | What was the final result?

You can use a big rag and a tire pressure gauge to check pressure. I suggest while its off and not running. Fuel pump is in tank. Remove back seat bottom and a cover is screwed down on passenger side. | | | 10-07-2009, 03:14 AM | #12 | Senior Member Join Date: Apr 2009 Location: TampaBay, Florida Posts: 104 | Fuel filter can get clogged up. Good time to change that. Fuel pumps when they get crud in there, they can run intermittatly. Suggest you change the fuel filter. I have removed the pump itself from the assembly and put a 2' clear line on it, mix a cup of TOLUOL & 3 cups gas, place in large bowl and then jumper the pump on and circulate that mix thru the pump several minutes and am Surprised at all the rust & crud in the mix bowl. The pumps I have done still are working today! If you jumper after reassembly and in tank, you can attech that clear line to the return line and watch the flow back into tank. A little risky, but if it is flowing fast, the fuel pressure regulator could be faulty. Hope your pumps run smoothly & consistant again! | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
