I have a 2002. changed the timing chain tensioner n guide. now it cranks but no spark. checked all fuses n relays. getting power to injectors, crank n cam sensors. no codes. no security light.. when key is on before cranking loud whining or buzz coming from drivers side in the back.

please help

 

Are you certain there's no spark? That sounds like it might have a bad fuel pump.

 

fuel pump is working

 

wow guys. everyone else has multiple replys on their questions. but not mine. why wont anyone help me? really would appreciate some help.

thanks

 

Check your fuses and the ENG CONT1 fuse (in Fusible Link and Fuse Box, by the battery) in particular.
Next, verify camshaft and crankshaft sensors are ok.
