m father has a 1991 suzuki side kick and is having a problem with the fuel injectors
the fuel pump is pumping and has propper fuel preesure the raced the wires from the injectors to the ecm and thinks that may be the problem
do the card board test first,pull injectors out hook everything back up,turn engine over let injectors spray on cardboard to see if all are spraying equal amounts of fuel spray,if all are equal they are fine,if 1 is off more or less on spray,you found the bad injector.if all are same,they fine.that will rule ot the injectors.could still be a ecm problem or timeing is off.check spark plugs and wires.
