94 LS 400
Driving my 94 LS 400 on fwy just start bogging out and dead. Before that
no problems , so i pulled over years ago my friend told me to disconnect
battery cable and reconnected. it started and ran for mile and car turned
off. did it one more time and work again for about mile and stop running.
tried to do the battery thing again. but never ran again.It cranks over but
wont start. Need suggestion to find problems asap. Thank u
Check the fuel pump ecu in the trunk. It likes to become disconnected. You can actually force the fuel pump on through the diagnostic box. Then try from there.
by passed the fuel pump relay with hot wire from battery to diagnostic FP and Bt. car starts fine. when i release foot off gas it dies. i change fuel pump relay and main EFI under hood. car starts run on its own. i press on gas to biuld up rpm and its starts booging out. please help thank u
