Car Forum / Subaru Cars / September 2008Does the fuel pump have to work to engage the starter?
Hi all, I have a 2000 outback, 2.5L. For the past month or so its had a problem getting steadily worse - first thing in the morning when I turn the key it only makes a "click" - the starter doesn't turn at all. After about 10 key turns the starter finally engages, it starts fine, and is usually fine the rest of the day. The battery voltage is good. Its in the shop now, and the guy is telling me he thinks it is the fuel pump. Is that possible? Would a lack of fuel pressure disengage the starter? My experience with cars is with older volkswagens where the starter and fuel pump circuits are independent - a bad fuel pump would still let the starter turn. Thanks for any help. cheers, Jeff I would focus on the starter solenoid. - Message posted using http://www.talkaboutautos.com/group/alt.autos.subaru More information at http://www.talkaboutautos.com/faq.htm > Hi all, > I have a 2000 outback, 2.5L.

There is enough contact for a small amount of current to flow but when the higher drain of a starter is just too much. Cleaning the terminals and re-tightening the cables solved the problem. If it happens somewhere inconvenient just attempting to gently twist the cables on the terminal post is usually enough to get you home. YMMV >> Hi all, >> I have a 2000 outback, 2.5L.

YMMV Hi, Years ago, a co-worker had a second "night job" driving a tow truck. He always carried a six pack of Coca Cola in the cab. Purpose: it was the best "field cleaner" anybody knew of for corroded connections. He said it's gotta be Coca Cola--apparently that brand has more of the "good stuff" than others--and gotta be the "real" stuff, not the diet or any other variants. Yeah, you're gonna have a sticky mess to clean up when you get home, but if it gets you there, that's a small price to pay, no? Rick The starter will work regardless of the condition of the fuel pump. The fuel pump will stop working a few seconds after the ignition key is turned to the on position if the starter does not turn the engine (crank position sensor) As stated by others, check your battery connections, engine grounds and your starter motor solenoid. Did you measure the battery voltage when trying to start the engine? It should be higher than 9V. Good luck! > Hi all, > I have a 2000 outback, 2.5L.

From the other posts, it should be obvious to you that you need to get your car out of that shop right now and go somewhere else. You have a boob working on your car. > Hi all, > I have a 2000 outback, 2.5L.

Thanks everyone. Yep, boobs working on the car - they eventually wanted to replace the starter - FOR $410!! With some help from the list archives, I replaced the contacts in the starter solenoid - One was nearly worn through and they were both corroded. Cost $10 and took about a half hour. Worked like a charm. Thanks again, Jeff > Hi all, > I have a 2000 outback, 2.5L. For the past month or so its had a [quoted text clipped - 14 lines] > cheers, > Jeff |
