Ok folks, its down to the bare wire itself. this is the ONLY thing keeping Envy from being on the road. EVERYTHING is complete other than this issue.

I have spark
I have fuel
I have compression as far as I know (doing a check tomorrow)
Battery is good
Starter is good
Fuses are all good
Scan Tool is showing NO codes
Scan Tool also says it has RPM while turning w/ the starter.


The car is NOT wanting to start. Its turning over freely with the starter, but its not firing up. It makes a pop sound every few attempts at starting it. What in the hell could be causing this?

All wires and harnesses are plugged in, plugs and wires are all good and connected properly.

Im beginning to wonder if possibly the cam sensor or crank sensor could be bad.


Please help, this has been a long time comming and this is stopping me from at last getting Envy back!

 

daily bump

 

it could be your crank sensor. i had a 95 eclipse that i let a shop do a timeing belt and water pump on and the lowered the motor for more room and pulled one of the crank sensor wires out and they dident know it. the car stood at the shop for a month and they replaced the pcm and all the other sensors till they seen the wire was just pulled out. the car would turn over but not crank. hope this help's

 

ok so a vote for the crank sensor.

Also a quickie for everyone: What is the avg compression for an LS1 so I'll know how #1 looks this afternoon?

 

If it is sparking then you probably don't have a cam / crank
sensor problem, at least not bad enough to prevent firing.
Crank position is only a fine-tuning.

I don't know what you've done to the motor but if it has
anything to do with big cam, you may need to give it some
pedal and not count on it catching normally as before. The
cranking mixture can end up way off.

 

its the 228R, vie tried adding gas while cranking and its not doing any good. It wont even fire really, it fires maybe once or twice on random clylinders and thats it

 

You sure you're getting spark at each coil, or just the one(s) you tested? How are you testing getting spark? Are you sure ALL grounds are connected (even the 3 on the back of the head)?

 

we let the plug wires arc off a screw driver. Im about 99% sure ALL grounds are hooked up. I am gonna double check everything though

 

Im going to vote for crank sensor. Mine would fire every.. 12 rotations I would say with a bad/incorrectly working sensor.

 

ok another vote for crank sensor. The crank sensor was sitting in a dirty box full of bolts and does have 93k on it, so maybe its jsut time for it to go bad.

 

Haha, wow. That would have been good to know in advance If you're sure all grounds are accounted for, I'm not sure what else it could be other than cam/crank sensor... unless your reluctor wheel was sitting in the same box as your crank sensor... anything more you care to share with us?

 

lol as a matter of fact yes.


Last week when my dad was helping me out some, he tripped voer the rack and sprained his ankle and busted his ***...and I got it on vid

 

Your Dad Brokeded Your Car!

 

lol possibly, so crank sensor seems to be the popular vote here. Have any idea how much they cost or a way to tell if its bad?

 

Yea, easy way to tell if it's bad..... your car won't start

$38.68 from GMPartsDirect. Part #12560228.

 

pfft

Smart-***. I don't wanna throw money at it if it may not be my problem, I was looknig for a way to guarentee its my problem and not something else

 

volt meter and figure out what it is supposed to read then while you're cranking...

 

He shared enough in his posts during the assembly of that poor engine that his problem(s) come as no surprise.

Tossed the crank sensor in a box and let it bang around w/ the other hardware, nice!

 

question: Would getting a video of it help any or is my description good enough? I can get one tomorrow if need be.

Also the intake is PUSHING air OUT isntead of pulling it in, dunno if that helps much.

 

A video of your car not starting? haha! Is your intake on backwards?
