I feel a little stupid now

it was working better then started having issues again

so this time I devise a low tech but useful test to see if the coil is getting signal

should have thought of this before , grab a known good spare coil and plug it in while the car is running and not firing on #4

WOW , yup , not a signal issue

I now believe I have a bad injector issue they will present the same way if not sending any fuel

ordering injectors , no where local can get them on less than a special order

also I do believe all the parts places get their data from one source napa , auto zone , Orielly , advanced , Amazon all broken on the look up of 2003 Suzuki Aerio injectors
found a cross reference and that the same injector was used in the Sidekick form 96-98 , the Honda Passport in 95

FOR Suzuki Aerio 2.0L 2002-2003

FOR Suzuki Esteem 1.8L 1999-2002

FOR Suzuki Sidekick 1.8L 1996-1998

FOR Honda Passport 2.6L 1995

FOR Isuzu Pickup 2.3L 1995

FOR Isuzu Rodeo 2.6L 1995

FOR Honda Passport 2.6L 1994

FOR Isuzu Amigo 2.6L 1994

FOR Isuzu Pickup 2.6L 1994

FOR Isuzu Rodeo 2.6L 1994

but any where looked up the computer will not confirm fit for a 2003 Suzuki Aerio
not just on their websites they can do no better in person at most of the autoparts places

so the new injectors should be here in a week
