New Intake, Carb, Dist Wont Start

[jperry1290]

So I installed a new intake and carb last week. The engine fired right up and ran great, but the oil pump shaft fell in the pan so I turned it off after a few secs. Just installed a new shaft replaced the pan gasket and now it wont fire up at all. The engine cranks till the batt dies. Carb seems to be getting fuel all electrical hook up are where they should be. When I pulled the dizzy I marked the shaft and rotor and both went back in on their marks. Could the dizzy be slightly off?

Did you take off the plug wires? If so double check that you got them back on right about the only thing I can think of it you marked the distributor and dropped it back in on the marks.

Did you put the rotor back in?

Don't ask...

 

[jperry1290]

everything is back in. the first time all the wires were removed. when i changed the oil pump shaft i left the wire connected to the cap and set it aside. i made sure the cap was on the right way.

Probably just out of time. You need to recheck to ensure the engine is back at TDC and the rotor is pointed to the #1 position on the firing order. You may even have it 180 off.

 

[fmcpeters]

Did you use the right firing order on the cap? Two different firing orders depending on what 302 you have.

If you rotated the engine at all, then do what broncnaz said and re-check for #1 TDC.
It's way too easy to be 180 off, unless the engine was not touched at all while the distributor was out.

In case that's not it, have you verified that you're getting a super hot white snappy spark at the plugs?

X3. It happens to the best of us it's probably 180* off. No bid deal.

you should copywrite this, and sell it to Petronix, no really, I chuckled when I read it.

 

[jperry1290]

Engine was not touched at all. Marks on the dizzy and rotor lined up. I will check spark this weekend

Thanks! That would be the private labeled version that Wild Horses sells.
The "marketing department" appreciates your feedback. ;D

Hmm, then I would say that, yes, according to your first question, you could be just far enough off that it won't start.
Usually though, if you've got a decent ignition system, even 10 or 15 degrees off it will still try to fire up. It might not run, but you'll hear it try to catch every once in awhile.
Was it acting like this, or were you getting no indication at all that it wanted to fire up?

I have been 1 tooth off , but still getting the marks to line up, and it wouldn't start, or barley start... I just ended up finding tdc again, and re timing it.

Speaking of getting your timing off....Is the 302 in interference motor?

 

[DirtDonk]

Good question. I don't think so. But it would depend on the cam. Stock, I'd say no though.

Different type of "timing" though. Just messing with the distributor doesn't change the relationship between the piston crowns and the valves.

Is that what you were asking?

You can still be off a bit have you ensured the rotor is algined with the #1 plug wire postion on the cap when the engine is at TDC?

yes, thank you sir!
Thanks. I was wondering if you would ding all your valves if the timing got off....but I see what you mean now.
