Hey guys new here with a recently purchased 2003 Audi a4 1.8t Quattro. So im having a huge problem not getting any spark, the car will not start cranks just fine but will not spark. I recently replaced crankcase vent valve. Last week the radio did the backlight thing so I tried disconnecting the battery, now the car wont start radio wont turn on (I was having rough starts before I disconnected battery). I light checkd all fuses including the ones next to the ecu. I need help please it is my only means of transportation!

 

god dam have you learned what ( , . ? ; ) are? itl do wonders if you learn that first.

ok after deciphering the paragraph, first did you reconnect battery? you said you disconnected it so check that. then check the 'break' fuse on the positive terminal connector to the battery.

and what you talking about radio did the backlight thing?

 

sorry I typed this in a hurry. and yes the battery is connected firmly. and it was doing the thing where it will always stay on but will not fully turn on, or come up in safe mode. search it and it will come up I guess its a common problem said to disconnect battery did not work for me.

 

I also did not find a fuse on my battery terminal

 

have u made sure the bat is fully charged??

 

look for this

no I have not tried checking for a full charge but wouldn't the car not crank if not fully charged? and the fuse is good.. it cranks and acts like it is going to start just wont spark man im lost idk what too do

 

check and replace spark plugs, coil packs, and try unplug the maf sensor and try to start.

do you have a check engine light?

 

No check engine light and I've checked coil packs and spark plugs ill try replacing this weekend anyother suggestions? Thanks for the help btw

 

so u are cranking right? Have u checked the presure at the fuel rail?
