1995 Won't Start
Topic Started: Aug 9 2012, 07:20 PM (752 Views)
crankcase


Hi all,

Got a 95 that had a 3cyl 5-speed that just got a motor from a 92 also 3 cyl 5-speed. I can't get it to start after the transplant :shit :smackface :shake :rtfm .


Facts: ^o)
The donar motor was running fine up to the time of the transplant.
I have spark after transplant.
Original 95 motor ran fine in the car (1995), that motor was removed and now is in my 93.
Intake is original to the first 95 motor and remained hooked up (so was not changed out in the motor swap).
No crank sensor plug on the 95 harness that I know of; besides, I have fire anyway.
Problem seems fuel related, but do hear fuel pump relay click at "key on".
Will not fire up, even with a small, medium, or large glug of gas into intake.
:ermm:


The throttle body has been sitting for a couple of years, but even if there was a problem there or in the fuel system,
souldn't it fire for a second or two with a glug of gas to the intake :news
:dunno ?


Thanks

possible the timing is off?

Did you connect the grounds to the back of the intake? Did you swap distributors and put the 95 distributor in the 92 engine?

You need to be using the distributor from the 95 car. Did you swap it like the intake?

Edit: BR types faster than me. :D

I agree. The intake and distributor stay with the car and just swap block/head assembly.

Thanks guys,

Timing should not have been adjusted as far as I can tell. The motor was running fine before the swap, but I will double check.

Intake grounds were never removed as the intake stayed with it's car, but I did doubled check that they are connected. The 92 distributor stayed with it's 1992 engine.

I can't remember what I did withe the 95 distributor. It may be in my 1993. I'll have to check, maybe it is laying around some place. Is there a way to tell it from an older distributor (possibly a 1992, 1993, or 1994)?

Theres a number on the distributor. I can tell you if that number is the same as a 95 or not.

Ok, thanks I will go look.

I am surprised that this could be the problem given that the 92 plugs into the 95 harness, and, there are no extra plugs on the harness I can see. Plus, I am getting fire. However, I get surprised all too often, so it's no surprise I sould get surprised.

To tell you the truth, I am not sure either why it would not work as long as it does not have vaccum advance built into it. I dont know what the differance would be. I just know I have heard differant ones had to swap their original distributors into differant year engines after engine swaps.

The 1995s i beleive is when they started putting 2 pins on the # 1 position in the dist, vs the pre 1995s where they only had one. This is just a crap shot, but maybe??

I figured it was because newer cars use a crank. shaft position sensor to produce a signal to run the low voltage coil. On the older cars, I thought the sensor under the distributor - turned by the cam shaft - produced the low voltage signal. Additional electronics are involved in refining the signal before supplying it to the low side of the coil. As I recall, the low side of the coil has a constant 8 to 10 DC volts on it. The signal coming from the sensor is used to ground the 8 to 10 volts, killing it. When the field collapses by being grounded, it induces a high voltage discharge from the secondary.

Remember the old school prank where you ask someone to hold the output of an induction coil while you turn it on? Everybody says "heck no"! You prove nothing happens by holding the leads while you turn it on. At that point it's easy to persuade someone to hold it while you turn it off, but that is when the big shock happens.

Regardless, it is a good time to try and learn the finer points of Metro distributors, and it's always good to learn something new.

95 does not have a crank sensor. That came in 96.

Got it to start and run reasonably well. It has a little trouble staying on when it tries to switches to low idle, but it is also safe to say it needs a tune up badly.

It is running with the 92 distributor, so I am assuming that at least the 92 to 95 distributors are interchangeable, perhaps even older. It seems there are at least 3 different variants of distributor: The vacuum advance type on older cars (late 80's/early 90's), the pick-up coil type (sensor behind the rotor, years about 92 to 95), and the type that uses a crank sensor (starting with the 96), but this is only a guess.

I started getting a little fire by putting gas in the intake yesterday, but it would never really run. I got nothing the first day (gas put in intake), signs of life the second (gas put in intake), and motor running on the third day (added more gas for a total of about 3 gallons, some gas put in intake to prime ).

Maybe I had flooded it or something, or the intake had been sitting for too long to work right away, I don’t have a good guess what was wrong. Also, I think the tank was bone dry and needed more than a couple of gallons to get fuel delivery (especially on jack stands), or the fuel pump needed to soak in gas a few days to come to life. I had initially put $5 with no signs of fuel delivery after two days. On the third day I put in another gallon and a half in, and it started running within a few tries.

It's all back together now, but one of my wheels is locked up. I will have to take it apart tomorrow to see why it is stuck.

Many thanks to everyone for the replys and ideas.

One more tidbit about my 92 transplant into a 95 body. The 95 thermostate housing (along with it's sensor) had to be put on the 92 engine. The 95 wireing harness requires it.
