03 Durango hard start acts like the battery is weak but will start after a few seconds and run fine.
I cleaned the dust out of my intake system was careful not to hit any sensors and since then
when i turn it over it acts as if it has a dead battery before it fires up. The battry is good and no
codes are being shown so im at a loss since it drives perfect after start up.
Check fuel pressue at the fuel rail read how many PSI and clean the MAF (mass air flow) sensor reads grams of air in entering the intact system... Then Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. write them down.
