Me and my buddy put in a new Raptor 700R4 in his 86 IROC. We pulled the distributor out to get to the top bellhousing bolts. Put everything back together and set the timing. Try to start car and it just cranks slowly. I have a car starter on the battery so the battery wont die. Pulled out #1 plug to make sure I was TDC incase the harmonic balancer timing mark was off for some reason. Well I pulled the plug and gas poured out. I pulled the rest of them and they all had gas. I manually cranked the car to get all the gas out of the cylinder chambers. Let it sit for 20 minutes to see if they will fill on their own. They didnt so i put the plugs back in and tried cranking. Still nothing. Just cranks slowly and sounds wierd. I dont know what to do. Anyone that can help it will be greatly appreciated. Thanks in advance.

 

Sounds like your battery is dead. Try trickle charging it overnight and see what happens. If you are lucky, you didn't hydrolock it

 

Battery's not dead I have a car starter on the battery so it doesnt use the battery juice. Hydrolock with gas? What would u do to check for that or fix it?

 

I posted this on third gen but I will do it here too...check your grounds...

 

Yea I saw it.....thanks....gonna check now.

 

Did you put the starter shims back in? That will make it turn slowly, and eventually kill the starter / ring gear....

 

We didnt remove the starter. Left the starter and flex plate all intact. All we removed was the distributor just to get the top bolts. I know the distributor is put in right and it should be jsut about dead on timing. Maybe a bit off but should still start. Im starting to think maybe the starter is going bad? My buddy said it used to sound like that before we put the tranny in. Said it had hard starts. I even took Aklims advice and put the battery on the charger over night. Nothing.

 

Try retarding the timing a bit at the distributor.....sometimes that will help a stubborn motor start. Also make sure it isn't 180* out (firing on the exhaust stroke,) that's a very common mistake.


If there was THAT much gas in the cylinders, you probably "washed" the cylinder walls which causes reduced compression. You can fix that by pulling the plugs and squirting oil in all the cylinders and letting it sit that way overnight. It'll smoke like a freight train when you crank it up but it'll help lube the rings and thusly help compression.


Good luck with it.
