So far I have had 2 mechanics look at my car, both said relatively the same thing, either crank sensor or it's not starting because of the airbags have been deployed. I bought my car wrecked and it hasn't started yet. I am getting fuel and air but no spark. The strange thing is when I tested it for spark a while ago there was spark, im sure. But when the mechanic came, he tested it and he got no spark. Why? Another problem is I tried to get to my airbag module and someone had taken it out before I had bought it. My question is can I buy a new one and just plug and play? Or does it have to match my vin number, etc. I am stuck! The engine cranks no problem, it won't start, sometimes it will hesitate and feel like it's about to start but dies again. I have changed the battery, checked every single fuse in the car, fuel pump seems to work, there is enough gas for it start, I cranked the engine by hand. I don't know what to do. Could it be the anti-theft system? Please help me out! Any advice is greatly appreciated!

 

Well if you saw spark and your mechanic didnt maybe time for a new mechanic. Also if it almost starts then dies then there is prolly most likely spark. Have you done a compression test to see if the engine is actually makeing any pressure?

 

I wanted to do a compression test and even got a compression tester but i didn't fit my engine. Would it be anything with the airbag system? Is it possible?

 

My 2 cents would be no it wouldnt be... I would think your engine has something else wrong with it. I would get a compression check done first then go from there. I mean it could be due to anti theft but the fact it almost starts and then dies is not a good sign..

 

Idk its weird, it only starts to start if it has sat for awhile, and then it just cranks forever

 

Right but if is massive engine failure that you cant see it will still just crank for days even if it doesnt have a hole in the block. Had a civic drop a valve and destroy itself but it would still crank forever

 

Lets hope I don't need a rebuild, engine only has 54k miles on it

 

So I found something new today, I get spark one time in the 3rd sparkplug, only once, never sparks again after each time I try to start it. All the other ones seem dead. Anyone have any ideas of what my problem could be?

 

So is the ecu throwing any codes?

 

Oops forgot to mention that I have 150 psi on all 4 cylinders. My mechanic told me to try installing an airbag module, he thinks thats the problem. I unfortunately don't have a OBD 2 scanners I can't scan for codes

 

Your mechanic or local part stores (e,g; Advanced, AutoZone, O'Rieley, PepBoys) should scan codes for you for free.

 

How are they supposed to scan it if my car doesnt drive?

 

You could buy a blue tooth code reader from ebay. (I got mine for about $10 shipped). Then download a reader app of your choice. (I used TORQUE pro from the Android app store for $5).

 

yea kinda hard for us to have much input if you dont know what codes the car is throwing. Just go buy a scanner for walmart then take it back when your done.
