Car won't start, cranks but no start.
I drive a 1996 subaru legacy l with about 160k miles on it. I drove it to school perfectly fine one day and then after school it it just would not start. We tried replacing the starter and the battery on the spot. Still wont change. So we uhaul towed it back. I tried spray starting fluid into the air intake and the car started up for like 5 seconds then sputtered out. We towed it home and took the alternator to orielys, they tested it bad but said it still worked. I then replaced the fuel pump as well but still wont start up and stay on. It ONLY turns over when started fluid is applied. I tried switching relays but im not quite sure if it was done right. The engine is not getting fuel because i un did the fuel filter fuel lines and no gas came out during the crank. I also DO NOT hear a primming noise from the new and previous fuel pump. Any ideas?

good call- like I said, I'm not even sure if the subies have it, they may be a little more advanced than a pickup truck

did you try blowing through your fuel filter? sounds like its clogged. or possibly bad ground or lack of power to the fuel pump. If its starting when you add starter fluid, it pretty much eliminates anything spark wise, IE. coil pack, plugs, etc. We dont have a distributor.

that's what I wasn't sure of. my truck would rank and rub for a few seconds, turned out it was the coil. but if the fuel pump won't even prime sounds like there's no power to it. check the wiring to it, see if it's broken or shorted. if not it may be time to replace it

Try replacing the crankshaft sensor. 4 moths ago I bought a 1995 legacy L that had the same problem wouldn't start. Turned out just to be a faulty sensor. I think it was like $40 at the auto parts store and they are usually fairly simple to install. The sensor is located under the alternator.

I know! Lets throw parts at hoping for a fix!
Start with the basics. Disconnect fuel hose from filter inlet, turn key. A small amount of fuel should spray out then stop. If no fuel check for power / ground at the pump. No power/ground, follow the harness up to each junction and recheck until you find the power /ground. Got fuel? Check for spark. Pull an ignition wire and see if it sparks against metal during cranking. No spark? Check for power and ground to coil (see above) Have fuel and spark? Check timing. Have fuel, spark and timing? Now you can make an educated shotgun diagnosis and swap the MAF sensor (there is a diag procedure for it, but it is easy to swap and readily found at a wrecking yard for $15) |

Test for power at the fuel pump plug, then work your way back from there to the fuse, relay ect...
If it starts with starting fluid, its not the coil. |

Go here - that's the '96 Service Manual. Download the Troubleshooting Section PDF (11.7MB file) and go to page 115. That's the start of the "Diagnosis for Engine Starting Failure" section. The first few parts (the starter motor, ECM, and ignition system) can be skipped (since we already know the engine will turn over, and the ignition system works because the engine tries to run with starting fluid applied), so then you get to the fuel system stuff on page 131. Start from there. |

The problem was solved it turned out that when i bought a fuel pump, the pump itself WAS ALSO FAULTY. Just my luck right? Firestone diagnosed all the groundings and wires were clear and worked fine. I got the car back and it runs fine now, thanks for all the help! . Also wondering if anyone knows why my doors no longer lock automatically, i press the driver door lock and all the doors lock as well, but now when i press it the doors dont respond?

imma go with faulty switch. it may have just given up the ghost. does the lock work when you use the key fob? (just assuming you have one)

No key fob, I usually just had to put the key in the driver side lock and all of them would unlock as soon as I manually unlocked the drivers door, now it only unlocks the drivers door and I must reach across to unlock all my passenger doors. I suppose you're supposed to hear a click under the dash as you unlock the doors but i dont hear anything anymore? I also accidently broke the door lock timer as in seperated the plastic casing from under the dash.

Then it appears you're on a SmartPhone, not a computer of some sort. Your spelling and grammar really sucks (dad with a 22yo and 20yo). Many years on forums. Does it crank? If it cranks, thus "cranks no start"? Who did the block swap/install? My first comment (based on above and your post), you're WAY over your head, check regional forum and have the car taken there. For that money, a good shop can do an engine pull, swap SB with gaskets, and reinstall. Then THEY have the warranty. Just saying. |
