Process of elimination.....car cranks cranks cranks but wont turn on......

Camshaft sensor?
Crankshaft sensor?
Fuel pump?
Injectors?
Spark plugs?
Clutch pedal?
Crank relay/fuse?
Alternator/starter?

Anything else? Anyone?

 

CKP = Crank position sensor.

If it's not plugged in or messed up, the PCM will not see the engine turning and won't give spark. I had to replace mine once, they're fairly cheap and can be changed without removing anything else, i'd say give it a shot.

 

Im doing this today. Did u had to case relearn you car?

 

 

Help guys, replace crank sensor and still wont fire up...... I have a mechanic here and we tested compression and is good......he says we dont have.spark.......help

 

We could not figure out. Sometime next week im replacing cam sensor......

 

well, if the crank sensor is good......and you have no spark. Check your ground for the coils.......it is the ground wire that attaches on the front of the transmission.

also, check the INJ fuse in your fuse block....should be a 10 amp fuse.

 

The ground wire on thr transmission, do I get to it from the bottom of transmission?
Can you give me lil more info on how to locate such fuse on block?

Thanks alot man for ur help.

 

Never mind, found inj fuse on block and its good. Ill check grounding tomo.

 

I found about 4 grounds. One on driver head light, one on driver firewall, one below head light and one on transmission.......oh and the one the goes from motor to valve.cover. Still wont fire up :%

 

And I have zero codes.....I even have an extra obd2 reader....and no codes

 

So I worked on my car today and replaced the cam sensor and still wont fire up......im really pissed off now........

 

I wish I could chime in with some direction to point you in, but all I really have is hang in there man.

 

Lol. Thanks. This sat. Im doing my timing again. See what happens.

 

did you do all your basic checks.....fuel pressure? Spark? all that........

 

Yes! I check fuel pressure, fuses, grounds, replaced sensors. I just dont think im getting any spark, I check wiring and looks good.

If all the above its good and if timing is off, wouldnt car still fire up at?

 

well, you can get a spark tester cheap at the store and check to see if you have spark.

The car will start and run even if the timing is a little off......now if it is way out, then probably not.

 

u make sure the sensor on the back of the firewall is plugged in...mine was unplugged after my build and i had the same issue..plugged it in and bam

 

Can you please give me more details where it is?

 

I think he is talking about the cam sensor.

 

Still no luck.

 

all your sensors plugged in?
still on stock tb?

dang rudy this sucks... it's like your chasing a ghost

 

Don't know if this has been covered, but did you remove/loosen the fuse box at all? I've seen problems happen from the connectors coming slightly unseated. Try removing and re-installing the big connectors under the fuse box, then go over all the fuses and relays and make sure they are pushed down properly.

 

Im actually going home early today to work more on my car and im trying this today.

Do u guys think the ignition control module is.bad?

 

update. cat is ready. picking it up today
