Please help 2003 H@ wont start

[350zguy]

First off thank you for any help I can get. I have a 2003 h2 that was runing fine and when I went out to start it a couple of hours later it wont start. H2 cranks and every few cranks is starts but very very rough and if I step on the gas there is no acceleration. I have no replaced the crank sensor and the throttle body, also swapped a computer and still no luck. fuel pressure is good. fuel filter switched out. I am running out of ideas. any help would be great

First thing is to get it checked for codes before you start "swaping" out parts with a hit or miss approach. Once checked for codes you will know (most of the time) what needs looked at.

Good luck, ed

How many miles? Plugs, wires, coils, too many to list. Need to scan it. Could be a plugged converter, water in the fuel, plugged injectors the list goes on...
