not your typical timing situation

[captainawesome]

so i got everything put back together today, and all looks well.

unfortunately it won't start. the motor cranks, but no dice.

i figure it is timing so i go to see where it is set at. i'll be damned if there isn't a mark on the pulley i have! i looked for a good hour and i am certain it doesn't exist on this one. i am sure it has to do with the fact that i am not using half of the other pulleys that came with the truck.

is there a way of finding tdc and marking it properly on the pulley, or am i shit out of luck without the proper pulley?

i also moved the crankshaft multiple rotations while the distributor was pulled, so i know it isn't even close. what to do? i looked in the manuals i have, but without the timing mark i have nothing to go off of.

if there are any tricks up someones sleeves out there, please shoot them this way!

thanks,
derrick

Pull #1 plug, stick your finger in hole, turn crank untill you stop getting pressure, should be pretty close to TDC, now it should be compression stroke as if it were exhaust it wouldnt have compression on the upstroke. There ya go! Good luck, let us know how it goes.

gonna give that a shot and hopefully it gets me close to where i need to be.

is it getting gas? After reading your thread, and I basically, no lie, did the exact same thing you did in your thread, I would check your fuel pump. Does it prime? I just got an 85 2.5 a little over a month ago with the broken timing gears. I ended up getting it running a few days ago. Mine had a problem w/ fuel pump when i went to start it. get a big hammer and hit that tank a couple times if the pump aint priming. LMK how it goes.

I wouldnt just go haulin off and hitting the Gas Tank, there are ways to verify fuel pressure, i.e. listen for pump, engage 12v to prime connector, watch injector as cranking to see if spraying. Hell for that matter shoot some starting fluid down the Throttle Body and see if she fires.

I always start with my gut instinct, if you had a notion the timing is off, check it. Then try the starting fluid test, might check and see if you have any spark at all. Let us know. Might need Cap and Rotor and Plugs?

was never a fuel issue or spark for that matter. i got it running late last night. it was definitely a timing issue. i found tdc and marked the pulley. then set the distributer where the manual told me to. started up first try. then adjusted the cap enough to get it running smoother. still got to tune it in, but it is running, and so far the only issue has been a bad seal on the valve cover...

thanks for the help.

its much easier to hit the tank with a 3 pound hammer.

Finger method isnt going to get you anywhere near close enough to TDC...

Go buy a piston stop... its pretty much a bolt with a rounded head on the end. You screw it into the #1 spark plug hole and rotate the engine by hand until it stops. Mark where the tab points on the pulley. Now rotate the motor the other way until it stops, and mark that point. TDC is exactly half way between the marks.

THEN, to set your distributor, you will need to use your finger to make sure your on the compression stroke rather than the exhaust stroke.

Then set your timing and give it a shot.

apparently it got him close enough to TDC to get the engine running,
so before you tell him something wont work
make sure he hasnt already gotten it to work

[SickSpeedMonte]

I never said it wouldnt get it running, I said it wouldnt get him close enough to TDC [i.e. to fix the problem properly]

Without knowing where TDC really is, you might as well just set it by ear, and thats just not good enough for me

Id much rather have an accurate idea of how my motor is timed, especially if you plan on discussing your tune with people on a forum... you cant just say, "Oh, #1 fires at 15* before the poof of air stops blowing on my finger."
