I've got no power! :(
Here's my situation. I was driving one day in my 1986.5 non-turbo, and i did a 180 turn. Smart me, i didn't put the clutch in all the way. So clutch was already going and i killed it. So i replaced the clutch, and put in an oil pump while i was in there (fyi I lifted the engine several inches to get the pan out). I also cleared out the Cat. So I get it all back together and im excited but then i had hardly any power (less then my 4 cylinder cherokee:nuts:)! Here's what ive tested.
I replaced the distributor cap and rotor. I checked the timing, it was right. Ran diagnosis but it said everything is ok. Checked vacuum lines, everything seems fine. It has new wires and hoses. So it seems like it has to be fuel pressure, bad spark plug, compression, or something else im not thinking about. But none of these really make since to me because it had all the power before i killed the clutch. So im wondering what happened in between killing the clutch and putting in oil pump and new clutch. Please Help! :x: |
See if you have any codes first. When you pulled the motor up did you disconnect any sensors like the knock sensor. It could be something pretty simple. Also with a new clutch make sure you do a break in, it might possibly be the clutch with the loss of power feeling.

You said you checked your timing... Are you talking about your valve timing or ignition timing or both?

I had something similar... when I could get the car to start, she'd idle at 400~500 rpm before jolting soo hard I shut her off, or she died out fairly quickly on her own.. didn't matter how much gas I gave either, the rpm's stayed pretty constant. Mine is an auto, so I doubt I'd even have gotten her to turn over if I were driving clutch. At any rate it was the distributor shaft itself... mechanics didn't find it till they took the cam covers and timing case off to do the timing.. I thought it was fuel pump issue, but pressure was good, they thought it could have been exhaust system clog as well... so since you seem to be looking down that road, I'd suggest getting in there and doing the full timing job and ensure all the shafts and gears are all on the up and up.

And thanks krem, i guess it could be the distributor itself, i sure hope not though. It isnt an exhaust clog cuz i have no Cat, so mabe mechanically the distributor is failing. Ill replace the fuel filter with one i have in the next day or two and see if that helps. |

Check here for more info, found this in the MKIII FAQ. |

Thanks! |
Never adjust timing by RPM or sound... this isn't 1920. :frown:

Okay, just making sure... not the kind of technique you really want spreading around as acceptable. Just don't stomp on it until you get it set properly.
I rather enjoyed the pun, actually. :rofl: |
Ok, so I fixed the timing, and guess what, it was running great! But... it was short lived. I went to start it up today after lunch and the engine cranked and cranked but didn't go. :( So...
I checked spark, it was good. Checked connections and hoses, all good. Even tried to jump it. The engine just wouldnt run by itself. So i thought fuel pressure... I shorted out the two terminals for the fuel pump, and the pump relay started buzzing and the wire got really hot. I checked the continuity in the relay and the resistor, and it said good. I did NOT check it in the relay with power hooked up to it. And when i turned the ignition to ON, the relay did not click. So does this mean bad relay? I also tried feelig the fuel line, and it didnt feel like there was pressure... So please, should i buy a new $50 relay or look for something else? Please :help: Side note: i did replace the fuel filter two days ago, but i looked at it and it seems fine. And yes, i do have fuel in my tank :) |
So i checked the power at the fuel pump connection and it was getting power. So if there was power to it but it wasnt working i figured the pump was bad. So i got it out, and ill be double checking tomorow and mabe try to fix it.
There was a lot of rust and gunk on it and the sock, and there was some that i could see in the old filter. So is there an easy way to de-rust-ify my tank? |
Mine does the same thing, and I also changed the fuel filter.. right after changing it it started doing it... They're saying bad compression in the valves, and for me to get the cams aligned, and the valves re-shimmed, but gah... any other suggestions?
