Syclone will not start

Little background:
Bought the truck in April of this year with a bad smoking problem. Basically a cloud of blow-by when I accelerated.

In june I had the motor rebuilt with all new parts, pistons, block cleaned up, heads cleaned, new valve springs, seals, the whole nine.

In august the motor was back in the truck and I was waiting on the current shop to finish Trans cooler install and re-assemble the front metal.

Now I know its late in the year, BUT, the shop has finally tried to get the truck rolling again.

They put a fresh battery, and some gas into her but she turns over to start but does not pop, start, rumble nothing. They said they could turn the key all day but it does nothing.

Done so far:
new gas, new starter, new plugs, new battery, new fluids with no leaks,
checked all connections
checked fuel pump, its working fine and delivers 40psi. (we turned it down from 60psi)
checked fuel injectors they are "pulsing" fine and deliver fuel
Checked spark and it is weaker than i remember but it is there.
Checked Distributor to make sure its correct and working, its fine.
Checked plug wires and they are fine

My only concern is the vehicle does have an older Ostrich emulator in the glove box. It was working great before the truck was taken apart but we do not have a computer with the necessary software to actually use the Ostrich now.

Would it have reset itself after some time with no power to the unit? Would that prevent the truck from starting?

Any other things I could check or any other ideas on why it does not start?

A well known and very informed shop and myself are stuck on what it could be.:rant:

Check for vacuum leaks? If not i would swap out the computer for a stock one and see if it help. Is the Tan wire connected or disconnected? Maybe your distributor is off.

My bets are in the computer, maybe the shorted it out with out realizing. Try another stock one with stock chip.

Make sure to replace the batteries in the ostrich and reload the bin. I had the same thing happen to me.:oops:

Re: Syclone will not start

First things I would try -

Flip the dist around 180 degrees.

Check that valvetrain events are happening when they should.

Check that somebody hasn't over-tightened the rockers such that there's no compression.

If you have spark, and fuel in the cylinders, the only thing left is timing or compression.

Checked compression. 60 psi in the cyl the shop checked. They said it might be because the motor has not been fired yet and rings have not had chance to seal.

Truck sounds like it wants to start but it acts like something is holding it from turning. Dist is fine we triple checked that.


What else?:(

I doubt that it would run on 60psi.... that's basically a dead cylinder. Like Dig said, I'd pull the valve covers off and check valvetrain events.... ask the shop how they adjusted the valves - that may provide some insight. Take a compression reading on another cylinder.

60 psi. Thats no good. new engine or not. Valve adjustment must be wrong. check there again.

i agree100% 60psi is a dead cilinder in my book./ should be 150 and i think 90 even has a hard time firing.
good luck with your progres

Re: Syclone will not start

I was thinking the exact thing - i spent a week trying to get mine to run and turned out I had 0 psi on all 6 - never gonna start. Did the rocker adjustmenmt and BAM, fired up - then I had all the other problems!

Do your valves - real easy.

Sounds like a good build and a small mistake - easy fix = fun truck.

Good luck.

I agree. The shop I am using did the adjustments, I will bring this up because i was thinking the same thing. Everything is brand new it should have 150 psi and it does not.

How long does it take to adjust the rockers?

Re: Syclone will not start

20 min to do the rockers - brand new engine mine had 165 - 175 on it. Pro rings, JE pistons, 4.030

Rockers.
