1994 Chrysler Lebaron turns over but won't start.

RE: 1994 Chrysler Lebaron turns over but won't start.
Tried the starter fluid again, did nothing. Took out all the spark plugs, cleaned them, cranked it with the plugs out to clear the cylinders, also shot air through them. Put all the plugs back in and tried starting it again and got a good pop but nothing more. Problem still persists... thinking about having someone come take a look at it because I am stumped here.

It sounds to me like you are 180* out on your distributor. That means that the plugs are firing on the exhaust stroke instead of the power stroke.

Thanks for picking up my slack there pal. I was going to mention that as part of the "if it still doesn't work then you have over looked something" sermon.Big Grin

The dist. rotor is lined up with the #1 terminal when the notch on the crank pully is in right spot, I believe at the 12° mark. I also felt the #1 piston to make sure it was all the way up so I know its TDC when all this lines up. There are however two notches on the pully... maybe I have been using the wrong one?

Turn the crank shaft so that the distributor rotor is pointing to #1. Now, turn the crank one complete revolution and come back to the same exact spot that you are at now, then look at the distributor. The piston will still be up on TDC, but the distributor will be 180* out. The crank will land in that position twice in it's 4 stroke cycle. One time it will be on the power stroke & the next time it will be on the exhaust stroke. If the plugs are firing on the exhaust stroke there is no fuel in the cylinder to fire. This is a very common mistake and very easy to make. Pull the distributor out enough to turn the rotor to #1 and give it a try.

Please let us know what you find.

RE: 1994 Chrysler Lebaron turns over but won't start.
So I turned the distributor 180°, but it made no difference. I have noticed when cranking, that there's a very strong smell of fuel coming out of the valve cover blow-by (I dont have it currently all connected to the air filter). Is this normal? I believe timing has to be the problem here. I have everything lined up, except for one cam seems not to be (rear). When I tried turning it so the notch lined up, it just snaps to the next position, which was even more off the mark. But the crank pully, front cam, and distributor all line up with their designated marks when at TDC. Also, if anyone knows, I've noticed there are three notches on the crankshaft pully. Why is this?

No, you should not smell fuel!

The rear cam must also be lined up properly.

Yes, there are several marks on the outside damper pulley because they use that engine in several vehicles. The mark you are looking for is on the cam / crank pulley and it lines up with a mark on the oil pump. (wish I has a picture to post) What you probably need to do to avoid a tear down is to pull #1 plug and figure out which timing mark is closest to TDC and go from there. Get BOTH cams lined up (may require a helper to hold things with a wrench) and get the belt back on. At this point line up the dist to #1 position.

If I recall correctly, on some years you can see the cam through the oil cap and verify where the cam lobes are pointing. They should both be one side or the other of the "up" position. (10 & 2 clock position?)

RE: 1994 Chrysler Lebaron turns over but won't start.
The problem definitely seems to be timing. I am having trouble with aligning the rear cam sprocket to it's alignment mark on the alternator bracket. Both cams turn in 90° intervals. The front cam lines up with its respective mark on one of the intervals, but the rear cam won't line up on any 90° interval. At this point I have the crankshaft sprocket, front cam sprocket, and distributor lined up up correctly. I basically have the rear cam shaft sitting between two of its intervals, but it doesn't feel right. The repair guide I have says to turn the crankshaft 2 revolutions for belt adjustment, but resistance is stopping me from making even one revolution. The book states this is because the piston is coming in contact with one of the valves. This doesnt make sense because my marks are lined up. I'm wondering if anyone knows what I am doing wrong, or is it a possibilty that the rear cam sprocket had been installed improperly by a previous owner. It was like this before when I assembled it, and it never made any tapping when turning it over by key. I just cannot turn it over a certain point manually due to resistance. Also, after TDC at #1, should the number one exhaust valve open?

Yes, the exhaust valve should be ready to open because right after firing that is the next part of the cycle. (get rid of the waste)

In order to move the cams a full turn you may need to move the crank a partial turn to lower the pistons. Secure the cams and then return the crank to the proper TDC location and install the belt. When it's all together that's when you turn the crank 2 turns again, which allows the slack in the belt to be removed and allows it to center itself on the gears. At this point you snug the nuts on the belt tensioner and double check to see if all the marke line up one more time before installing the covers.

BTW, only turn things in the normal direction of rotation!
