Skyman207 Posted April 30 Share Posted April 30 Hey everybody ! I’m having a problem with getting my XT (4wd turbo) to start, really at all, got it a while ago (was running on purchase) but had a stuck transmission and decided to pull both, put a ‘new’ trans in, and to pull and clean up a lot of seals and outside of the engine, fix some leaks, etc, didn’t mess anywhere inside the heads, or touch the distributor but redid the timing/belts IAW the FSM (car luckily came with all 6 sections) long story short, put it all back together and surprise crank no start, I've been digging through the manuals for weeks and i am hopelessly stuck, im new to Subarus, (and pre-OBDII in general) so any help anyone can give me would be greatly appreciated. we have fuel pressure, spark, air, good battery, and a stumble on starting fluid, but no power going to the injectors, all grounds per manual were cleaned and sanded, injectors were resistance checked as good, the diagnostic LED on the ECM is just on and unblinking and won’t throw a code at all and the FSM has sent me in circles and upside down looking for test plugs and modules, from what i can tell there’s no voltage going to the injectors during crank, and it might be a CAS failure in the distributor and it’s just not telling the ECM that the motors even moving hence no spray or the ECM has frozen or internally failed and I’m just not sure how to rule either of those out any insight to help get this ol girl started again? Or atleast a way to isolate the problem? Link to comment Share on other sites More sharing options...
scoobydube Posted April 30 Share Posted April 30 The distributors don't last forever. Plus, you need to take them apart and make sure that all the moving parts have grease and swing properly. I have gone through one distributor every 100,000 miles or less. The little black plastic electronic thing a ma jig in the center goes bad, then there is no spark to the plugs. As far as electricity to the injectors, that could be the black wire in the fusible links, that runs the entire engine. Another culprit could be the capacitor that wires into the coil, that will cause the engine to not start. Obviously, you have to have installed the timing belts exactly right, and you need prior experience to do that. Coils also go bad. Then there is the electrical connectors of the hot wire coming off of the alternator. That wire with the looped end connector loses it's conductivity due to overheating, so you have to cut back the lead and reinstall a new loop end to reattach to the alternator. Ground wires also lose their ability to conduct electricity at the body end of the wire. If they are stiff, they are bad. If before you took everything apart, and tried to run the electric windows at the same time the engine was running, but that caused the engine to miss or drop in rpm, then the ground wire is bad. I use two ground wires to be safe. There are two out of the six rectifiers under the dash over your left knee, that will cause the engine to not run. You can look for a burned one or replace all of them. Don't buy them from Subaru, because they will sell you the same rectifier that you can buy on the internet for$10, but for $50.
