Rough start then dies
Hey guys. I have a 97 grand Cherokee loredo V6 that starts pretty good, then at times it struggles to start and when it does it dies about 15 seconds later. The car will take a few times to start but after it warms up its good. It cranks good but nothing.
I replaced the spark plugs, spark plug wires, distributor cap, rotor and the crank shaft sensor but still nothing. Any ideas?

Hola Raul, bienvenido al foro, i will write to you in english because of respect for those who don´t speak spanish. Check your ECU harnesses for rust or sulfate and clean it with some dielectric cleaner, also the ECU has 2 little torx bolts, replace both with shorter ones, because long bolts cause short circuits inside the ECU, good luck and don´t forget telling us how did you fix your problem, saludos!!
