hi guys
i dont know what happened but i recently installed a switch on the fusebox for a cutout switch,(where theré's 3 available place),and swapped my battery for a old one cause mine was dead..
i enter the car in the garage...did some little rev at neutral,and car suddenly shut off..
after that,not able to restart the anymore..
car cranks but just wont start..
i got fuel pressure,the fuel pump prime,car crank but just dont start..i checked ignition fuse and fuse under dash...
my keys recognized the car,and im on aem ems v2..
if someone could help me..dont know where to look..
pretty sure car is doing fire,just dont start..
was working fine before and did nothing..also removed the switch wire i installed and didnt change anything

 

Pull the spark plugs and see if they are wet with gas. You may not be getting spark.

 

ok thanks wind,im gonna take a look... does it could do this if the battery is ground(bad)? the battey look strong when i crank..
in case no spark,where do i look for after? is there a coil fuse or something like that that i didnt see?

 

Dry plugs ---> fuel delivery issues.

Wet plugs ---> electrical-ignition issues.

See what plugs looks like, first.

 

Rule out fuel to the cylinder issue. Spray some starting fluid into IM, see if starts for a second.

Rule out spark. See if plug has any spark when you crank motor. Remove a plug. Reconnect coil pack, such that plug rests against block, coil pack is plugged in and connected to plug. Crank motor. See a fat spark at plug?
