No spark. 2004 cavalier. New head gasket new timing chain


Spark is generally generated by an impulse from the crank position sensor. Check that it is connected correctly and that the pick-up plate that it reads wasn't damaged or turned the wrong way around during the cam chain replacement.

In some cases, if the cam timing is out, the comparison between cam and crank sensors can cause no spark so double check that too just to be safe.

Turns over but no spark, after new head askets


are you asking this 3 times removed? really>????
is this the 4 cam v6 or 2?
the 4 cam has 2 gears for 2cams and belt drive. 6ve1
the 2 cam v6 has no gears.
6ve1 engine, they have real names and all run different EFI controls
all do.

ok no spark (tested the wrong way !!!)
fuses good. or not, we test them not guess, on (looks ok)
you need to run compression on any engine with new head (or pulled) or leakdown 10x more safe.
that be first. you can bend valves on the 4 cam engine
(not on 2valve engines,one per bank)
forget the 2 CMP sensors on rear of both heads.?
spark dead on all 6 spark plugs
ckp dead.
CMP 1 or 2 dead
fuse blown.
has 6 ignition coils right, (usa) called C.O.P.'S.

i bet you didnt scan it cranking did you
if the pcm on the 6ve1 engine, sees cams turn wrong
it cuts spark to keep from bending over the head valves
the cams must be timed correctly and not in a cavalier manor
what's your engine vin code 8th digit
that tells the helper what engine is there, as you seem not to know.
there are 3 different V6 used here.

i see you really didnt check spark, just assumed it.
why? extend one cop, use fresh grounded test spark plug
omg got spark omg on all 6 in fact
omg compression is dead. x6 bent valves.

i never ever ever, crank any DOHC engine (messed with like this)
until the leak down test passes, by hand with shop air.
this act,saves further damage

VIN = Y or W
eight digit of vin is engine code. !!!
are 4 camsl

its flooding
so, compression is gone
sparks gone
or it over injecting for some reasons
if compression is ok, 150psi +
and parks good
secret wide open throttle will clear floods, (cut fuel mode )
but all this is risky on any 4 cam interference engine.

when i put the belt back (assuming cams not removed)
I check cam timing 2 time or 3 times, or risk bending valves.
6ve1
then do the leak down test now, just like you are there.
hand turned crank. (at each of the 6 TDC points(skills)
opps its got 0psi on many cylinder
that means valves are bent.

here is the SM quote step 4 belt install
WARNING If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.
one can just throw an engine like that back together.
they also told you to set cam timing first, before pulling heads
or damage can happen,
but that depends on the event
belt snapped, jump cogs or just leaking head gasket.

Simple head gasket


No, you don't have to remove the spark plugs. That will allow it to turn easier because it cant compress in the cylinder, but not a must. As far as the rest of the removal, yes that's how it needs to be done. If you don't want to do all that work, you can ad SeaFoam. It does have good reviews, but its not the proper way to fix. Whenever you add any kind of additive, you risk causing more damage. Save yourself the future head ache and replace the head gasket. If you are confident you can just remove what you see needs to be removed, go with it. All instructions are base on a mechanics standpoint, and lets face it the more work performed the higher the payout. Just use your eyes and good judgment, You will see exactly what needs to be removed..... Good luck.

MY 1998 DODGE NEON WONT START. I WAS TOLD TO REPLACE THE CAM SENSOR AND DID SO. THE COIL WAS CHECKED AND ITS GOOD. WHAT IS THE PROBLEM


I bought one with the same problem, the mechanic chaged: camshaft sensor (it was ok), the coil pack (was ok too), the pcmodule( ok too) the arness (ok) and did not start. I checked timing belt and was ok. but wen I did the compresion test , every cilynder was too low ( 10 30 an 0), my firsth idea was head gasket replecement,and wen was remooving the camshaft sprocket Bingo: the small pin was broken (that means that the camshaft sprocket was not align in time) Had to chage the head an the camshaft both in terrible shape. bad lobes and cam bearings worn out. wen I crancked it start at the first time. PD. the head wasnt craked, the head gasket was good too and the valves ok .

I have a suzuki escudo(sidekick) 1993 and have no spark


If its not the igniter, maybe you forgot to time the engine (timing marks will align at #4 firing poition, not at #1) when you remove the cam shaft.If the engine is not properly timed during assembly, it will not surely fire.

What would cause my1999 Saturn sl1 not to start after a new head gasket was put on? Ok so today we replaced the head gasket on my 1999 Saturn Sl1 single cam. We made sure the timing chain was put back on...


Check the cam/crank sensors. Also, if the car happens to have a distributor, make sure it is not 180 degrees off. If this does not help, then do a compression check. Remember, and engine only needs three things to run. Fuel, Spark, and Compression. (in order of course.) The firing order for your engine is 1,4,3,2.
