Have power but the car want crank
When I boost jump the car it will crank, could it be something wrong with the ECU

Other than a redesigned interior, automatic climate control, and 6 disc cd player, Suzuki switched up the trim levels for 2003. Instead of Standard and Plus, the XL-7 now comes in 2WD and 4WD versions of the Touring and Limited SUV's. All 4 trims have a 2.7 L, 183 hp V6 engine. Touring trims have standard 5 speed manual and optional 4 speed automatic transmission while Limited trims have 4 speed automatic transmission.
Gas mileage comes out to 17 mpg in the city and 20 on the highway. All 4 trims have 4 doors, seat 7, and tow up to 3000 lbs. If you need more standard and optional features, go with a Limited trim. Finally, for those who need to carry a lot, the XL-7 delivers up to 75 cubic feet of cargo space with the second and third row folded down.
Overall, drivers will tell you that the XL-7 gives you decent handling and good seating capacity at a low price. However, passenger space in the back rows gets a bit tight and V6 powertrain could use a little extra juice. If you're looking for a solid first SUV with limited funds, look into an XL-7.
