rebuilt the whole damn thing. as in, changed head gasket, and some other gaskets :P so not really rebuild, ok fine, i changed the headgasket.

so now, i have fuel, spark, and air, but the damn thing won't start.
i have the exhaust manifold off, so when i crank it, i see the damn fuel comin out white, like, no combustion.

and i checked for spark, i changed new wires and new spark plugs, and the spark is there, i see it. bosch platinums.

i crank i crank, i crank some more, like, 20 seconds, well, friend cranks, and i push the timing back and forth. not even close to firing up.

checked compression, brand new head gasket, but everything else is origional, head and pistons rings are old. 120 150 150 150

what is the ups! start damnit, help me. i heard i should check coolant and air temp sensors, but damn, it doesnt even get close to startin.

i checked grounds, didnt really know which ones, i only see one near the egr/exhaust manifold tiny little ground, and the other ground is the one near the battery tray, injectors are all grounded to the head.

help me

im so sad.

sounds like your dizzy is off by a couple teeth

There is a problem with your one cylinder that has the compression of 120. Your cam timing or even ignition timing may also be wrong.

Sounds like your distributor maybe off, just like Neme said. You have to take the oil pump, distributor off and make adjustments.

Ok, so I THINK my distributor is off, pretty sure actually.
But anyone else think it's not OK for my compression to be 120/150/150/150

aznpoopy · 11-09-2005, 07:59 PM

compression #'s l ike that ... its not healthy

it shouldn't keep the car from starting, however.

Clean your IACV, mine did the same when I changed injector o-rings, just turned over, wouldnt fire. Eventually it just cranked right up.
