1G wont start after new timing belt install

[dszx13]

installed new timing belt and balance shaft belt an it wont crank. made sure the #1 piston was at tdc, all timing is lined up right. gettin fuel an spark in all wires. wandering if anyone can help me out. first attempt to do this

 

[turbotalon31]

did u set it at tdc on compression or intake stroke ? did u try to turn it by hand ?

 

[dszx13]

when i set tdc i felt air blow out. so im guessing compression stroke. the manual said to turn it 2 full rotations by hand an i did

 

[djordan97]

are you sure you lined it up on the correct timing marks?

 

[turbotalon31]

its 6 times for all the marks to line back up if i remember. and what cylinder did u use for #1 the one closest to the timing belt?

 

[dszx13]

number 1 piston being closest to the timing belt. not sure if its right. tried it again today an it still wont crank. when i checked the timing all was good but the oil sprocket it was off so i redone the belt. pulled the valve cover an everything looked good i jus dont kno why it wont run.

There is a good chance that you bent valves, do a compression test. The job is very precise that you get it right, dead on.

 

[dszx13]

it didnt look bent. everything did what it should

 

[92AWDHX40]

Well go backwards what was wrong if anything before the timing belt, job. I had nicked my valves everything was dead on, but nicked them just enough so i had no compression. This time everything is redone, and it runs. If all was good before the tb job then something went wrong. Compression test will resolve your problem, for starters.

the belt broke doin 20 mph. ill do the compression check next time i go to the shop. but all the springs were doin there job so i dont think the valves are bent

 

[92AWDHX40]

Let us know.

 

[dszx13]

wandering if it might be a vaccum leak or something

 

[Squirrel8811]

If it broke while driving you probably have bent valves.

I would say you most likley bent your valves. Doing 20 or 100 your motor doesn't care. 2 things can't be in the same place at the same time at any speed.
Compression test.

 

[timsturbotalon]

if car was runnning you have bent valves. mine done same thing about 20 mph bent 12 of the 16valves.

 

[turbotalon31]

what book did u use ? u do know that 90 91 have different timing marks than a 92 94 sure u dident use the wrong diagram ?

 

[dszx13]

i used the chiltons book. i got the marks right. 100 percent positive. put the belt on/off 8 times. jus hoping i was wrong. when i try to crank it..it sounds like it wants to but it aint. if i can i'll get a video

Did you replace the head once the belt broke? If you didn't, your valves are bent and you MUST get the head rebuilt!

 

[turbotalon31]

definatly bent valves the first 1 ever did i bent valves just cranking it. second time it happened when i was backing out the garage basically coasting bent the valves also. just save urself the hassle of trying to figure it out and pull the head almost positive ull find bent valves

can u spin it over by hand without alot of resistance?

 

[belize1334]

How fast you were going is not relevant. If the engine was spinning and the belt broke then you have bent valves. As for the not cranking issue, if you can turn it by hand the starter should also be able to turn it regardless of whether your bent valves allow it to actually run. If it won't crank then I'd suspect the starter as either bad or not being triggered. Did you pull or disconnect the starter for any reason? Try shorting the battery straight to the starter and see if it cranks.

You would not be able to tell if you have bent valve by taking off the valve pan cover. You have to do a compression test or pull the head. If the belt broke it is almost a 100 percent guarantee that you have valve damage.

When trying to start the car does it seem to crank faster than it used to?
With compression loss the engine will crank faster because there is little to no compression building on the compression stroke.

Edit: I missed where OP said not cranking I thought he was meaning it would turn over but not start.

 

[dszx13]

i didnt unhook the starter. jus the battery. ill do a compression check this weekend. what numbers should i be looking for?

 

[92AWDHX40]

Good 164, mi 121 psi.

 

[FLASH1970]

You should look for about 150psi on each cylinder if i remember right. But the Chilton's manual will tell you...

 

[dszx13]

ok. thanks for y'alls input. when i do the test i'll post the results an figure what to do then. i appreciate it!
