Well i just got my new dizzy in and the car still wont start.It doesnt crank over all it does is click.The clicking sound is coming straight from the main fuel relay area.could this be why my car wont start.ive already spent lots of $$ trying to get my car to start but i havent succeded.Do u guys think its my main realy.Also i do hear the fuel pump come on.

"it doesnt crank over at all?"

is your starter turning the motor?

the main relay is suppose to click/tick, but NOT continuously.
you gotta take it one step at a time, is your starter turning the motor? yes, then are you getting spark?

are you sure the fuel is flowing through the lines (simply by hearing the fuel pump do its job doesnt necessarily mean fuel is being fed into the rail)?

are you getting a code from the ecu?

are your injectors actually doing there job and delivering the fuel into the chambers?

wiring, everything wired up correctly and grounded properly?

check the ground on the thermostat to make sur its tight
