95 Camry rebuilt 5sfe will not start - Toyota Nation Forum : Toyota Car and Truck Forums

I rebuilt my 5s-fe for the camry and it will not start. I have checked the timing several times, installed both cams correctly, and replaced the distributor. It appears to be fetting fuel and spark and is timed correctly but still nothing, I am stumped on this one. It just cranks and doesn't hit at all.

Are you sure your timings right on the cam? The cam shoudl be lined up with the v notch and not the circular dot. Its a common mistake.

yes, the v-notch in the center of the bearing cap. NOT the dot to the left of it. The int to exh timing on the cams was sketchy in the haynes book but I am fairly certian that I got it right. Also, am I on track with thinking that if it were a little out it would at least try to fire or just run real bad? This thing isn't even trying to run at all.

If its a couple degrees off itll run, just bad. It sounds to me like your timings off somewhere.

Have you checked fuel pressure?

You have to be pretty far off (like, more than a couple of teeth on the belt) for it not to try to do something.

Is the spark big and blue? I've heard of and seen a lot of aftermarket dizzys be DOA.

Are you 100% sure you've got the spark wires hooked up right? I've seen more than one reference have the wrong firing order for the 5S-FE

I think we just went through this with someone else - so . . .

back to the basics. . . Fuel, comrpession and spark are required.

Lets Verify these!
If you have a compression gauge, put it in #1 and crank it. Does it build and have compression? (I'll get back to alternate means in a sec). If yes, this is good. 140-165 ish

Timing: if you turn the balancer and align the timimg to TDC we know the piston will be up at TDC. Remove the #1 spark plug and verify this. Use a screw driver and gently rock the crank back and forth a very short distance. If at TDC, the s/d will hardly move at all. What we don't know is if this is the firing stroke. Use of the compression gauge OR a rubber plug in the #1 hole will tell you this as you reach TDC.
How? Turn it by hand. If the valve timing is correct, you'll feel the cork, rubber plug, finger, (what ever you stick in there to seal the hole with) will begin to push away from the hole. As long as its pushing away, keep turning until TDC aligns on the crank balancer.

This is #1 and all valves are closed, building compression. You just need a spark at the right time and fuel!

Now VERIFY the #1 plug wires location on the Distributor cap. Lets say its at the 3'Olclock position. Mark with a sharpie the electrode terminal from the #1 wire on the cap TO THE BASE of the distributor. Remove the Dizzi cap! The Rotor should be pointed at that spot at the BASE of the dizzy.

If it's not, you have the dizzi indexed to the wrong place. If its close, you may need to pull it out and move it a tooth.

Make corrections as needed.

With the dizzi aligned, does it run?

NO?
Pull the plugs and drop about 1/4 tsp iof gas in each of the holes. Reassemble ignition system. Does it start run and die? If yes, you have fuel issue.

If NO, and it still does nothing. You likely have no spark. Now we go down a seperate path for sparkies. . .

Tell us what you find!

Its seems unlikey that both Fuelie and Sparkie quit at once, but it happens. Use this to figure it out and let us know how it goes!

Good Luck!

As it turns out, the Hayne's book was dead wrong on the timing from intake to exhaust cams. I had a look at my Dad's Rav4 book and it set the record strait. Apparently my problem was two fold. I was using the wrong marks when I set the exh. Cam in and did not preload the spring between the halves. without the Rav4 book it would have been a nightmare to figure out. Hopefully I am not alone with this problem cause I feel like a total idiot. LOL.
