I have been studying what to do about my '96 Taurus 3.0 OHV concerning it not starting. I have taken it to a 'not so hot' mechanic here and they were total idiots about what is wrong. The engine was replaced with a brand new one in 2001. Not the wiring. It now has approx. 35,000 miles on it. It quit running, at 65mph, like it was running out of gas (full tank). I have checked for gasoline pressure at the injector bank, LOTS of pressure. Didn't check injectors themselves but when I pulled every sp. plug to check for spark (all had spark), they were wet and smelled of gasoline. So I assume (?) they were getting gas. The plugs (Rapid Fire) all looked very normal with no extraordinary buildup with only normal wear etc. 8000 miles on this set. The mechanic did a compression check without and then with oil in the cyls. Same readings 230, 245, 160 and 175. He did nothing else except put new spark plugs in. He said the engine was shot!! Frankly, I just don't believe this as there could be too many other things that could give low compressions. This engine has run and started perfectly (excepting a bad VSS which I replaced) since I got it in 2002. I would like to do more tests on it when I get it home, One being a Leakdown test. Only problem is I have never done one. Can anyone explain how this is done and can I do it or do I have to take it to another shop? Should I rule out a bad or jumped timing chain? What other tests should I do concerning this low compression? Since it won't start, all the tests so far have had to be done only while cranking the engine with the starter. Unfortunately the OBDII does not work so I have to check things the old fashioned way. If you can, please HELP! Thanks |

| I have a low compression in my no.1 cylinder along with a misfire. To repair the engine isn't worth the cost. Can I unplug that fuel injector so that the unfired fuel won't ruin the cat converter? If I do unplug it will the engine then send more fuel to the other injectors to make up for it sensing the no. 1 cylinder not getting anything? | |

Replying to: acadiarush (Nov 23, 2005 3:47 pm) Also, the rear driver door won't go down? Does anyone know if this is an electrical problem with a fuse, and which fuse to change? Are these issue related? Man it's getting cold here in Idaho, and I would rather fix this myself than drop $$$. Thank you, Halen 262 |
