you know I cleaned my battery connections a few days ago and the engine has idled proper ever since. It would idle errattic sometimes and that stopped after the cleaning but those two cables off the batt to the starter are 99 original ill check them and the batts thanks

starts cold every time wont start after reaching normal operating temp.

engine still wont start after replacing position and timing sensors, ground relay, starter, fuel return check valve. Im stumped anybody got a suggestion

where is ground relay located? replaced starter, it was bad. I have not checked g relay but nextran told me to check starter for amp draw, that was a problem but did not check relay. I appreciate responce helps me a bunch, thanks just don't know where g relay is.

i pulled ecm off engine cleaned pins they were corroded pretty bad put it back engine runs smooth but still wont start, supply pump seems ok it has good resistance after a couple of pushes on pump, you just have to shoot a short quick shot of either to fire it off thanks for responding ill check sensor connections, if you think of anything else i would appreciate hearing it thanks again

i have strong resistance immediately when pumping

i have a 99 ch 613 e tech 460, my engine wont start 8 out of 10 times without starting fluid it takes just a littie shot and it will fire off no white smoke or any for that matter, turns over but wont start. also codes 1 3, 2 1, and 2 3 come up contiously during operation. can anyone help thanks.
