Won't Start

45 PSI is what I recorderd...... but id doesn't seem to even want to catch..... not even a studder!!!!

and you're sure you're getting spark????

Good question, how did you test to varify spark, and is it enough to fire the plugs. You could be flooded by now and may need to clean and dry or replace the plugs to het it started.

If you do in fact have spark, it could be

Broken timing chain
Slipped timing
Wiped the lobes off the cam
Entire rocker arm shaft came loose or broke
You got a hole(s) in your piston(s)


What I would do is, pull the distributor cap off and turn over the engine. Make sure the rotor turns.

If it does, pop odd a valve cover. Turn the motor over and make sure the rocker arms move up and down.

If they do, do a compression test.

If you have fuel, spark and compression, you should have a running truck.

If his engine turns over evenily, you can rull out the rocker arm idea,hole in a pistonand a broken timing chain all of which will cause an irratic starting peed of the engine. I don't think it is a lobe issue cause that is something that will come on gradually and should only cause a compression on a specific piston. I still like the slip timing idea caused by a tired timing chain.
Well this one will be an interesting one.

I will get to it on thursday!!!! The weird part was it just quit.......Was running fine and had no problems...then died....... when I saw the fuel pressure at 45 psi and then i checked for spark and had it I was a little confused myself..... I will keep yuguys updated on what I figure out!!!

I was reading and came across an article on the security system allowing the car to turn over, have fuel pressure, but not start. I'm not sure how you reset it, but someone might know. Just a thought.....

I tried the "reset" under the hood...still no luck!!

I reread what you said and had another thought. You could have spark, fuel line pressure, and compression and it wouldn't start if in fact your fuel isn't fuel. Is your tank really low and maybe water in it? Just another thought..

[Discodude19]

My tank was very, very low and at first i thought i just ran out of gas. Later i added about 2 gallons. And as far as water none of that except the fact that it rained the night before.

[Discodude19]

Also normally when i unscrew the gas cap it lets out pressure, when i added the gas and took the cap off there was no pressure that realeased.

Broken Timing Chain? That what happened to me - i was getting spark, fuel but chain was broken -it would turn over but wouldnt start - as mentioned above

[Funrover]

Well...there is spark...fuel.......compression...and the rotor turns when cranked....any morre thoughts?

[Hank]

Is fuel making it into the cylinders? If you pull a plug, does fuel spit out when you turn the engine over?

[Funrover]

Yup...fuel is makeing it in!!!! I also set it at TDC and looked at the position of the rotor...all is where is needs to be..I am lost!!
